<p>Engineering confidence is our primary product. We are not testers, but rather infrastructure engineers building the sophisticated automation and CI/CD frameworks that make deploying to production a non-event. Our mission is to architect the systems, repository standards, and automated guardrails that empower every engineer in the company to ship at terminal velocity with total confidence. By building the foundational tools that guarantee production readiness, you will play a direct role in driving Sev-1 incidents toward zero and ensuring that our organization can move fast without the fear of breaking things.</p>
<p><strong>What You'll Achieve: Key Responsibilities</strong></p>
<p>As a core member of the team, you will own the execution of critical projects and contribute to the evolution of our testing ecosystem:</p>
<ul>
<li><strong>Own and Enhance Frameworks:</strong> Take ownership of our integration and E2E testing frameworks across both backend and frontend stacks. You will ensure they are fast, reliable, and easy for other teams to adopt.</li>
<li><strong>CI/CD Integration:</strong> Contribute to how we execute tests within our CI system. You will focus on optimizing feedback loops so engineers know exactly where they stand in minutes.</li>
<li><strong>Establish Standards:</strong> Help define and implement general rules for our repositories, ensuring consistency in how unit tests are written and how code quality is measured.</li>
<li><strong>Scalable Feature &amp; Coverage Contribution:</strong> Actively develop new tools that simplify complex testing scenarios while identifying and backfilling critical testing gaps at scale. You will build systems for data mocking and service isolation that ensure high-fidelity coverage across our most complex application flows.</li>
<li><strong>AI-Driven Quality Innovation:</strong> Help lead the charge in leveraging AI to accelerate our testing lifecycle. You will explore and implement AI-powered tools for automated regression detection, flaky test analysis, and intelligent test generation to decrease time-to-completion for features.</li>
<li><strong>Collaborative Problem Solving:</strong> Partner with feature teams to troubleshoot flaky tests and identify gaps in our current coverage, making proactive suggestions to improve our overall safety net.</li>
<li><strong>Operational Excellence:</strong> Monitor the health of our test suites and CI pipelines, taking pride in maintaining a stable and performant environment for the entire engineering organization.</li>
</ul>
<p>&nbsp;</p>
<h3><strong>What Makes This Role Exciting</strong></h3>
<ul>
<li><strong>Direct Impact on Stability: </strong>Your work is the primary line of defense against Sev 1 incidents. When the platform stays up and customers stay happy, it is because of the systems you help maintain.</li>
<li><strong>Full-Stack Visibility:</strong> Because you own the E2E suite, you will gain a deep understanding of how our entire ecosystem fits together, from frontend UI components to complex backend microservices.</li>
<li><strong>Autonomy and Growth:</strong> While we provide the vision, you provide the execution. You will have the space to own your work end-to-end, propose technical improvements, and see your suggestions implemented company-wide.</li>
<li><strong>High-Leverage Work:</strong> You are not just building one feature for one customer. You are building the tools that hundreds of your fellow engineers use every single day to do their jobs better.</li>
</ul>
<p><strong>Who You Are:&nbsp;</strong></p>
<p>&nbsp;</p>
<ul>
<li><strong>Analytical Problem Solver:</strong> You have 2+ years of software engineering experience with a focus on writing clean, maintainable code. You excel at debugging complex issues and performing root-cause analysis, using those learnings to implement systemic improvements that prevent future regressions.</li>
<li><strong>Quality Advocate: </strong>You find satisfaction in a well-organized test suite. You understand that testing is a fundamental part of the development lifecycle, not an afterthought.</li>
<li><strong>Technical Generalist: </strong>You are comfortable working across the stack. Whether it is debugging a React component in an E2E test or optimizing a Python integration test, you are ready to dive in.</li>
<li><strong>AI-Forward Thinker:</strong> You are excited about the intersection of AI and Software Quality. You are eager to help us leverage AI to automate test generation, identify flaky patterns, and accelerate the overall development lifecycle.</li>
<li><strong>Ownership Mindset: </strong>You do not just wait for tickets. You look for ways to make things better. You take pride in owning a project from the initial PR to its successful deployment and monitoring.</li>
<li><strong>CI/CD Familiarity: </strong>You have experience with, or a strong desire to learn, CI/CD tools and understand how automated testing fits into a modern deployment pipeline.</li>
</ul>
<p><strong>Technologies we use (not exhaustive):</strong></p>
<ul>
<li><strong>Backend:</strong> Python, Django, Go</li>
<li><strong>Frontend:</strong> React, TypeScript, JavaScript</li>
<li><strong>Testing Frameworks:</strong> Playwright, Cypress, Pytest, Jest</li>
<li><strong>Infrastructure and CI:</strong> AWS, Kubernetes, Terraform, Helm, Buildkite</li>
<li><strong>Data:</strong> MySQL, Redis, Kafka</li>
<li><strong>AI Tools:</strong> Integration with Claude, Cursor, Copilot, or internal AI enablement frameworks</li>
</ul><div class="content-pay-transparency"><div class="pay-input"><div class="description"><p><strong>Massachusetts Applicants:<br></strong>It is unlawful in Massachusetts to require or administer a lie detector test as a condition of employment or continued employment.

<p><strong>(Boston, MA onsite 5x a week)</strong></p>
<p>&nbsp;</p>
<p><strong>Why you should join the Recommendations Platform Team&nbsp;</strong></p>
<p>The Recommendations Platform Team is responsible for developing and deploying machine learning-based recommendation systems at scale, and building out the foundation for new use cases for technologies such as embedding-based similarity search to power agentic workflows. We are evolving to act as a layer of product intelligence, making sense of customer data in order to personalize messages with the right item at the right time across multiple channels. Our systems span large-scale data pipelines and querying workflows, batch training and inference, and low-latency online retrieval and ranking systems. We are also building the experimentation, tracking, and measurement capabilities needed to evaluate recommendation quality and business impact over time.</p>
<p>&nbsp;</p>
<p><strong>How you will make a difference&nbsp;</strong></p>
<ul>
<li><strong>Contribute to the architecture and evolution of backend services</strong> that power product recommendations across Klaviyo experiences (email, SMS, KAgent, onsite, etc.), meeting standards for reliability, performance, and clear APIs.</li>
<li><strong>Contribute to and maintain robust, large-scale data processing pipelines</strong> (e.g., using Apache Spark or similar frameworks) that transform raw events and catalog data into high-quality features and inputs for recommendation models, ensuring data quality and lineage.</li>
<li><strong>Collaborate closely with ML engineers and product stakeholders to productionize recommendation models</strong>—defining high-level interfaces, feature contracts, and deployment patterns for batch and/or real-time inference systems.</li>
<li><strong>Contribute to the development of the vector database</strong> that powers recommendation, semantic search, and agentic use cases.</li>
<li><strong>Ensure data and service observability</strong> (metrics, logging, tracing, dashboards) to facilitate recommendations that are correct, explainable, fast, and highly available for all customers.</li>
<li><strong>Work with Product to break down projects</strong> into clear milestones, balancing the need for rapid experimentation with technical soundness and long-term maintainability.</li>
<li><strong>Lead data-driven decision making and A/B testing efforts</strong>—ensuring recommendation systems are instrumented with the right metrics, and independently interpreting results to guide future product and engineering iterations.</li>
<li><strong>Participate in on-call and incident response for the systems you own,</strong> driving major post-incident follow-ups that substantially improve the resilience and operability of our recommendation stack.</li>
<li><strong>Integrate AI into your and the team’s development workflow from the ground up</strong>—for example, using AI to accelerate development, automate complex tests, or build smarter monitoring and debugging tools.</li>
<li><strong>Share knowledge, mentor junior engineers, and define best practices</strong> on working with large-scale data frameworks, distributed systems, and integrating ML into production systems.</li>
</ul>
<p><strong>Who you are</strong></p>
<ul>
<li><strong>2+ years of professional software engineering experience with a focus on backend and distributed systems at scale;</strong> you have a proven track record working on production services and optimizing for latency, reliability, and operability as well as business requirements.&nbsp;</li>

<li><strong>Comfortable with cloud-native architectures (AWS preferred) and container orchestration (e.g., Kubernetes);</strong> you manage infrastructure and CI/CD pipelines as a core part of your development process.</li>
<li><strong>Experience in data-driven decision making and A/B testing</strong>—you can define (or are interested in learning how to) how to instrument experiments, read and interpret results, and ensure learnings are folded back into system design.</li>
<li><strong>Comfortable designing and querying data models</strong> in relational, analytical, and NoSQL datastores (e.g., Postgres, MySQL, data warehouses, Redis, vector databases).</li>
<li><strong>Feel at home with modern DevOps practices</strong> (CI/CD, monitoring, alerting) and how to apply them to architect large-scale data and recommendation systems.</li>
<li><strong>Track record of owning features end-to-end</strong>—from initial technical design and implementation through rollout, monitoring, and sustained iteration.</li>
<li><strong>Excellent technical collaborator and communicator:</strong> you can clearly articulate complex technical trade-offs to both technical peers and non-technical partners, and you work effectively to drive alignment across ML Engineers, Software Engineers, PMs, and other teams.</li>
<li><strong>You are a self-starter who has actively experimented with AI</strong> in work or personal projects and are excited to responsibly explore and define new AI tools and workflows to enhance team productivity and system intelligence.</li>
</ul>
<p><strong>Nice to have</strong></p>
<ul>
<li>Previous experience working on product recommendation systems or adjacent ML-powered features (ranking, personalization, search, or similar).</li>
<li>Experience with big data frameworks such as Apache Spark (or similar technologies like Flink, Beam, etc.) for architecting and building complex batch or streaming pipelines.</li>

Software Engineer II - Recommendations

<div class="content-intro"><p><em>At Klaviyo, we value the unique backgrounds, experiences and perspectives each Klaviyo (we call ourselves Klaviyos) brings to our workplace each and every day. We believe everyone deserves a fair shot at success and appreciate the experiences each person brings beyond the traditional job requirements.

<p>Klaviyo's AI &amp; Analytics pillar is building the intelligence layer behind the product — models that optimize send times, predict churn, surface product recommendations, and power the agentic experiences that help marketers run their business autonomously. With over 200,000+ customers, billions of consumer profiles, and hundreds of billions of messages and conversion events, Klaviyo has the data and scale to build world-class AI and machine learning products.</p>
<p>The ML Platform team is the engine that makes all of that possible. Every model that ships at Klaviyo — whether it's predicting the best moment to send an email or powering a Marketing Agent recommendation — runs on infrastructure this team owns. That includes training pipelines (built on Ray), experiment tracking and model registries (MLflow), inference serving infrastructure, feature pipelines, and emerging workflow orchestration tooling (Prefect). As Klaviyo leans harder into agentic products and generative AI, the demands on this infrastructure are accelerating — and so is the team's impact.</p>
<p>This PM role is embedded in Palo Alto alongside our ML engineering org. You'll have the kind of proximity to your engineering team that most ML PMs only read about.</p>
<h2><strong>About the Role</strong></h2>
<p>We're looking for a Senior Product Manager to own both what Klaviyo's ML models do and the platform that makes building them possible. That's a deliberate pairing: the best ML PM at this stage isn't someone who thinks exclusively about model quality or exclusively about infrastructure tooling — it's someone who can reason across both, connecting platform investment to model outcomes and model outcomes to customer impact.</p>
<p>On the modeling side, you'll own the roadmap for Klaviyo's core predictive models — smart send time, audience optimization, product recommendations, and churn prediction — as well as the AI-assisted content and agent capabilities that are growing in importance. You'll define what quality means for each model family, set the evaluation frameworks, and work with ML engineers and data scientists to ensure improvements compound over time.</p>
<p>On the platform side, you'll own the roadmap for the internal infrastructure that every ML team at Klaviyo builds on: DART (our Ray-based offline ML job platform), MLflow, model serving, feature pipelines, and Prefect. Your job is to make Klaviyo's ML engineers faster, safer, and more confident shipping models to production — and to make sure the platform stays ahead of, not behind, the pace of our AI ambitions.</p>
<p>This is a highly technical role. You'll be the only PM on the team, embedded with engineering in Palo Alto, and you'll need to earn credibility by speaking the language — not by knowing how to code, but by knowing enough about distributed training, inference tradeoffs, and ML developer experience to make good calls and ask the right questions.</p>
<h2><strong>How You'll Make a Difference</strong></h2>
<ul>
<li>Own the product strategy and roadmap for Klaviyo's core predictive and generative ML models — including smart send time, audience optimization, product recommendations, and churn prediction — defining what "better" looks like and how we get there</li>
<li>Own the ML Platform roadmap: training infrastructure (DART/Ray), experiment tracking (MLflow), model serving, feature pipelines, and emerging tooling (Prefect) — making time-to-production for new models a first-class metric and driving it down continuously</li>
<li>Build and maintain evaluation and monitoring frameworks so model quality is measurable, regressions are caught before they reach customers, and improvements compound over time</li>
<li>Partner with engineering leadership on build vs. buy decisions across the ML stack — ensuring the platform evolves ahead of the needs of ML and AI product teams, not reactively behind them</li>
<li>Connect platform and modeling investments to customer and business outcomes, working with go-to-market and customer success teams to ensure AI-powered features are well-understood and improving based on real feedback</li>
<li>Ensure platform reliability, observability, and cost efficiency for ML workloads operating across hundreds of billions of events and 200,000+ customers</li>
<li>Reduce developer experience friction for ML and AI engineers — making it materially easier and faster to ship new models safely and maintain them in production</li>
<li>As Klaviyo's agent products place new demands on inference infrastructure and LLM tooling, help shape how the ML platform evolves to meet those needs</li>
</ul>
<h2><strong>Who You Are</strong></h2>
<ul>
<li>You have 5+ years of product management experience, ideally owning ML, AI, or data platform products in a production environment — not just products that use AI as a feature</li>
<li>You have working knowledge of ML systems — training pipelines, model serving, experiment tracking, feature stores, or related infrastructure — and understand the tradeoffs involved in building and operating them at scale</li>
<li>You know how to connect internal platform investments to customer and business outcomes, and can translate "we improved training throughput by 40%" into a product story leadership and go-to-market partners actually care about</li>
<li>You're comfortable being the only PM in a highly technical room — you know when to drive decisions, when to defer to engineers, and how to build credibility without needing to be the most technical person there</li>
<li>You think in terms of systems and tradeoffs — model quality, inference latency, training cost, developer velocity — and can make well-reasoned prioritization decisions when they conflict</li>
<li>You can balance long-term platform investments with short-term product needs, and know when to build, buy, or defer</li>
<li>You communicate clearly and can translate complex ML and infrastructure concepts into business impact for both technical and non-technical audiences</li>
<li>You have a track record of moving roadmaps and priorities across ML, data science, infrastructure, and product teams without direct authority</li>
</ul>
<h2><strong>Nice to Have</strong></h2>
<ul>
<li>Hands-on prior-career background in ML engineering, data science, or software engineering</li>
<li>Familiarity with Ray, MLflow, Prefect, or similar distributed compute and workflow orchestration platforms</li>
<li>Experience with LLM inference infrastructure or building products on top of generative AI and agent frameworks</li>
<li>Exposure to high-volume, low-latency inference systems or large-scale distributed training workloads</li>
<li>Experience as a PM embedded with an ML engineering team in a B2B SaaS or high-growth tech context</li>
<li>Prior experience at a martech, ecommerce, or data-forward SaaS company</li>
<li>Familiarity with Klaviyo's product surface and the email/SMS marketing ecosystem</li>

<p>The AI &amp; Analytics pillar powers how Klaviyo's customers understand their business, trust their data, and take action on insights. Our work spans the full analytics stack: from the foundational reporting infrastructure that every team at Klaviyo builds on top of, to AI-powered experiences that help marketers understand performance, explore their data, and take action — all from within the Klaviyo platform.</p>
<p>As Klaviyo expands into Enterprise, Omnichannel, and AI-driven marketing, our analytics platform is evolving to match. That means modernizing the infrastructure underneath reporting, building AI experiences that are genuinely trustworthy and differentiated, and extending analytics to serve the needs of multi-brand Enterprise customers for the first time.</p>
<h2><strong>About the Role</strong></h2>
<p>We're looking for a Senior Product Manager to own Klaviyo's Analytics AI product area — a cluster of tightly connected product challenges at the intersection of AI, data infrastructure, and analytics UX.</p>
<p>Your primary and largest ownership area is the <strong>Analytics Agent</strong>: Klaviyo's in-product AI inside Composer that answers performance questions, surfaces insights, and serves as the shared intelligence foundation that every other Expert Agent in Klaviyo relies on for data grounding.</p>
<p>How do you build an AI that gives answers a marketer can trust — ones that match the numbers already in the app? How do you go beyond returning metrics to delivering the "why" and the recommended next action? How do you reach data that generic LLMs over public APIs structurally cannot, and translate complex query infrastructure into simple, intuitive experiences that customers actually use? These are the questions this role is organized around.</p>
<p>Beyond the Analytics Agent, this PM will own AI-native analytics UX (data visualization skills, AI-generated dashboards), the PM-side of Klaviyo's query infrastructure modernization, multi-brand organization analytics experiences, and ongoing platform health for core reporting surfaces.</p>
<p>This is a high-visibility, high-leverage seat. The work you deliver will be felt across Klaviyo's entire agentic product suite, the Analytics SKU, and the Enterprise customer base.</p>
<h2><strong>How You'll Make a Difference</strong></h2>
<ul>
<li>Own strategy and H2+ roadmap execution for the Analytics Agent across five pillars: Trust (quality, correctness, and reaching parity), Intelligence (metrics → insight → recommendation → action), Breadth (expanding to data that public APIs can't reach), Foundation (agent-as-a-tool architecture for Composer's multi-agent orchestration layer), and Experience (AI-generated charts, dashboards, and proactive in-context insights)</li>
<li>Build and own the quality measurement system for the Analytics Agent — design evals, LLM-as-judge scoring, and a golden set of production cases so the team can measure quality improvements reliably every week</li>
<li>Own AI-generated analytics UX: define the right integration model between Composer's charting infrastructure, Core Reporting, and Analytics AI; ship a coherent NLI-driven visualization and dashboard creation experience</li>
<li>Own the PM-side of Klaviyo's query infrastructure transition — as query execution engine migrates and new analytics capabilities become possible, define what that unlocks for customers, sequence migration priorities by customer value, and ensure the transition doesn't create gaps in existing surfaces</li>
<li>Partner closely with the hiring manager on multi-account analytics &amp; activation experiences for Enterprise Organizations</li>
<li>Work cross-functionally to drive multi-team alignment across a fast-moving, architecturally complex product area</li>
<li>Write clear, rigorous product specs for AI behaviors, data-heavy features, and platform-level changes — artifacts that reflect deep understanding of edge cases, data semantics, and technical tradeoffs</li>
<li>Maintain accountability for the health, quality, and steady-state reliability of core reporting surfaces</li>
</ul>
<h2><strong>Who You Are</strong></h2>
<ul>
<li>You have 3–5+ years of product management experience, with a strong track record of independently owning complex, multi-stakeholder product areas from strategy through execution</li>
<li>You have direct, hands-on experience building AI or ML-powered products — not just products that use AI as a feature, but products where model quality, evaluation, and data grounding were core PM responsibilities</li>
<li>You have a strong data and analytics product background — you've built or owned analytics, reporting, data visualization, or BI products and you care deeply about data accuracy, metric consistency, and customer trust in data</li>
<li>You have demonstrated UX judgment for complex data experiences: you translate hard query infrastructure problems into simple, intuitive user-facing patterns, and you have a strong opinion on what makes a great data product</li>
<li>You're comfortable working alongside major platform migrations or infrastructure transitions and can translate technical architecture shifts into product decisions and customer-value sequencing</li>
<li>You can influence multi-team roadmaps without direct authority — you've navigated competing priorities across platform, feature, and infrastructure teams and made things move</li>
<li>You write clear, rigorous product specs for data-heavy and AI features — your artifacts reflect deep understanding of edge cases, failure modes, and technical tradeoffs</li>
<li>You're technically fluent enough to reason about LLM-based systems (evals, agent architecture, tool-use, retrieval), query infrastructure (semantic layers, schema design, query performance), and how they connect to customer-facing product decisions</li>
</ul>
<h2><strong>Nice to Have</strong></h2>
<ul>
<li>Prior ownership of an in-product AI assistant, chatbot, or analytics agent in a B2B SaaS context</li>
<li>Experience designing agent-to-agent interfaces or building products within a multi-agent orchestration system</li>
<li>Familiarity with semantic data layers, query abstraction, or analytics infrastructure modernization projects</li>
<li>Background in e-commerce, martech, or CDPs/CRMs, or marketing analytics — you understand how marketers think about campaign performance, attribution, and audience analysis</li>
<li>Experience working closely with data engineering or data platform teams as a PM partner</li>
<li>Experience supporting Enterprise or upmarket customers with complex, multi-account or multi-brand data needs</li>

<h2>Team Overview</h2>
<p>The Data Platform organization owns the foundational data systems that power analytics, AI/ML, and product use cases across Klaviyo. This Senior Lead role is anchored in the Data Lake domain, while working broadly across Data Platform to support and align with adjacent teams.</p>
<p>&nbsp;</p>
<p>In practice, this role helps shape and connect the technical direction across lakehouse storage and compute, data onboarding and orchestration, modeled data layers, and the operational automation that keeps the platform reliable, observable, and usable at scale. The role requires strong judgment in connecting work across teams rather than optimizing only within a single technical boundary.</p>
<p>&nbsp;</p>
<p>The scope is not just to improve one system in isolation, but to make the broader data platform more trustworthy, scalable, and easier to operate. That includes aligning roadmaps across teams, supporting high-impact and complex cross-team projects, and helping represent Data Platform clearly to partner teams and stakeholders.</p>
<h2>How You’ll Make an Impact</h2>
<p>As a Senior Lead Software Engineer in Data Platform, with primary focus on Data Lake, you will:</p>
<p>&nbsp;</p>
<ul>
<li>Independently own and drive high-impact technical objectives that span multiple Data Platform teams, especially Data Lake while supporting work that intersects with Data Automation and Data Warehouse.</li>
<li>Help align technical roadmaps across Data Platform so teams are making coherent investments against shared priorities, dependencies, and long-term platform direction.</li>
<li>Lead large, complex, cross-team initiatives from discovery through rollout and long-term ownership, especially where success depends on coordination across organizational and technical boundaries.</li>
<li>Make high-judgment architectural decisions across core platform systems including lakehouse storage and compute, orchestration, modeled data layers, and operational automation, and create reference patterns that other teams can reuse.</li>
<li>Establish paved paths, standards, and shared abstractions that reduce repetitive manual work and make onboarding, operating, and evolving data systems dramatically faster and more reliable across the platform.</li>
<li>Partner closely with engineering, product, analytics, AI/ML, and governance stakeholders, and represent Data Platform clearly in cross-functional discussions that require both technical depth and strong external communication.</li>
<li>Help drive alignment on complex projects by clarifying trade-offs, surfacing dependencies early, and ensuring teams stay coordinated as priorities or execution details shift.</li>
<li>Be accountable, with team and engineering leaders, for the long-term technical health of the systems in your scope across reliability, scalability, performance, cost, security, and operational excellence.</li>
<li>Own the response to complex platform issues when needed, working directly with engineers across teams during high-severity situations and turning lessons learned into lasting improvements in architecture, operations, and communication.</li>
<li>Invest in the growth of senior and lead engineers through design reviews, RFC feedback, architectural coaching, and active participation in senior engineering hiring.</li>
</ul>
<h2>Who You Are</h2>
<ul>
<li>You are passionate about building platforms for the long term and can balance technical quality, engineering velocity, and business impact across multiple teams.</li>
<li>You have 12+ years of software engineering experience and deep knowledge of distributed systems, data platform architecture, and large-scale analytical processing.</li>
<li>You bring deep expertise in one or more core Data Platform problem spaces such as lakehouse architecture, data ingestion and transformation, distributed compute, data warehousing, platform reliability, or developer-facing data infrastructure, while maintaining strong system-level thinking across interconnected areas.</li>
<li>You have independently led large, ambiguous, multi-quarter programs and have a track record of making clear architectural calls, breaking through technical obstacles, and leading teams through critical operational moments.</li>
<li>You have strong hands-on experience with the kinds of systems this role touches, including Iceberg-based storage, Spark or EMR-based compute, Airflow-based orchestration, Python-based data platform tooling, modeled data systems, and AWS-hosted infrastructure.</li>
<li>You understand how to build and operate trustworthy data platforms, including schema evolution, materialization patterns, observability, backfills, repairs, audits, access controls, and cost-aware platform operations.</li>
<li>You are highly effective at driving outcomes through influence and technical leadership rather than direct authority, and you communicate clearly with both technical and non-technical partners.</li>
<li>You are passionate about mentoring other engineers and creating the patterns, guidance, and opportunities that help senior engineers and leads grow.</li>
<li>You enjoy improving how systems and teams work, whether through better architecture, tooling, workflows, or operating practices.</li>
</ul>
<h2>Nice to Have</h2>
<ul>
<li>Experience with custom built databases and CDM-style modeled data layers, especially transforming landing data into durable, queryable business entities.</li>
<li>Experience building or extending managed table frameworks such as Materialized Views and related operational tooling.</li>
<li>Experience with data governance, ownership, discoverability, residency, or regulated-data programs such as GDPR or HIPAA.</li>
<li>Experience building platform automation for backfills, repairs, optimization, autoscaling, and agentic support for engineers operating complex data systems.</li>
</ul>
<h2>Technologies We Use</h2>
<p>Core technologies and platform components used by the Data Lake team include:</p>
<p>&nbsp;</p>
<ul>
<li>Iceberg S3 tables for the foundational storage layer.</li>
<li>Spark / EMR for large-scale analytical compute.</li>
<li>Airflow for orchestration, scheduling, and workflow tracking.</li>
<li>Materialized Views and Python-based platform frameworks for managed Iceberg tables and related data tooling.</li>
<li>Landing-table loaders and CDM tables for ingestion and modeled data transformations that support KDB.</li>
<li>Audit and operational automation for maintenance, observability, backfills, repairs, optimization, autoscaling, and access controls.</li>
<li>AWS-hosted infrastructure supporting the lakehouse platform and its surrounding systems.</li>
