A lot of companies say they’re “mission-driven.” Our unique corporate structure guarantees that every decision we make upholds our mission: to ensure the internet remains open and accessible. Beholden to neither shareholders nor investors, Mozilla Corporation is wholly owned by the not-for-profit Mozilla Foundation.

Along with our communities of 20,000+ contributors and collaborators, Mozilla Corporation’s staff designs, builds, and distributes software that allows people to enjoy the internet on their own terms. Our flagship product — the Firefox browser — has expanded into a family of products that protects users and alerts them of risks, safeguards passwords and provides a secure VPN (with more to come).

By maintaining a safe, open internet we're helping humanity, while also helping the individual humans employed here to reach their personal and professional goals. With a relatively small team serving hundreds of millions of people, a culture of exploration, and a commitment to mentorship, opportunities abound to learn and grow at Mozilla.

MZLA Technologies Corporation (MZLA) is a wholly owned, for-profit subsidiary of the Mozilla Foundation and home to Thunderbird, our flagship open-source email and productivity platform empowering more than 20 million people around the world.

The opportunity
Thunderbolt is an open-source, cross-platform AI product initiative from the team behind Thunderbird. It is being built around a clear principle: people and organizations should be able to use AI while staying in control of their data, infrastructure, model choices, and long-term options. Thunderbolt is designed to support flexible deployment models, integrations with AI tools and workflows, and use cases across desktop, web, and mobile.
We are looking for a Senior Engineering Manager to lead engineering execution, people management, and operating practices for Thunderbolt as it moves from R&amp;D incubation into a more mature product and enterprise development phase. This role will help the team define what production-ready means at this stage: stronger release discipline, clearer ownership, higher user-facing product quality, stronger engineering practices, and a more scalable operating model.
This is a hands-on technical management role. The Senior Engineering Manager will manage a senior engineering team, stay closely engaged with the codebase and technical execution, coordinate work across employees, contractors, and technical partners, and help the team deliver a reliable, enterprise-ready open-source AI product. The right person will bring strong people management skills, strong product engineering judgment, and enough technical depth to evaluate engineering work credibly, support architectural and implementation tradeoffs, and help the team keep shipping with quality.
What you’ll do&nbsp;
<ul>
<li style="font-weight: 400;">Lead engineering execution by clarifying priorities, ownership, timelines, risks, dependencies, and quality expectations.</li>
<li style="font-weight: 400;">Manage engineers and contractors, including coaching, feedback, prioritization, performance support, and team development.</li>
<li style="font-weight: 400;">Stay close to the codebase by contributing code, reviewing technical work, evaluating tradeoffs, and helping the team maintain momentum and quality.</li>
<li style="font-weight: 400;">Partner with technical and product leadership to turn product direction, AI strategy, user experience goals, and technical priorities into coordinated engineering plans.</li>
<li style="font-weight: 400;">Establish planning, review, release, and follow-through practices that improve predictability and reduce bottlenecks.</li>
<li style="font-weight: 400;">Maintain high standards for code quality, testing, documentation, reliability, security awareness, maintainability, and release readiness.</li>
<li style="font-weight: 400;">Build strong product and architectural context across AI-enabled workflows, integrations, local-first or customer-controlled architectures, and release requirements.</li>
<li style="font-weight: 400;">Partner across product, design, enterprise-facing teams, and technical leadership to balance speed, user experience, privacy, quality, enterprise readiness, and long-term sustainability.</li>
<li style="font-weight: 400;">Lead hiring, onboarding, and resource planning as the Thunderbolt engineering team grows.</li>
<li style="font-weight: 400;">Help Thunderbolt scale from an incubation-stage product into a reliable, enterprise-ready open-source AI product.</li>
</ul>
What you bring&nbsp;
<ul>
<li style="font-weight: 400;">15+ years of professional software development experience, including significant experience in senior engineering leadership or complex product delivery roles.</li>
<li style="font-weight: 400;">5+ years of experience managing technical teams, including senior engineers or senior individual contributors.</li>
<li style="font-weight: 400;">A track record of leading a team that shipped polished, top-tier products held to a genuine standard of craft.</li>
<li style="font-weight: 400;">Strong ability to translate ambiguous product and technical direction into clear plans, ownership models, and delivery momentum.</li>
<li style="font-weight: 400;">Technical fluency with AI-enabled products, including the ability to evaluate tradeoffs across areas such as LLM applications, RAG workflows, agents, enterprise search, automation, on-device AI, or AI evaluation.</li>
<li style="font-weight: 400;">Demonstrated experience delivering complex applications across multiple platforms, such as desktop, web, and mobile, using technologies such as Tauri, Electron, React Native, or comparable frameworks.</li>
<li style="font-weight: 400;">Experience with enterprise software, regulated environments, or similarly complex technical products, including security, privacy, compliance readiness, administration, integrations, and customer-controlled deployment models.</li>
<li style="font-weight: 400;">Practical experience with local-first, offline-capable, self-hosted, hybrid, on-premise, air-gapped, or other customer-controlled product architectures, including tradeoffs related to data storage, sync, privacy, reliability, and user experience.</li>
<li style="font-weight: 400;">Experience improving engineering practices related to technical planning, code review, release readiness, testing, documentation, CI/CD, maintainability, or technical debt management.</li>
<li style="font-weight: 400;">Excellent communication skills around technical prioritization, release risk, ownership, quality expectations, and tradeoffs.</li>
</ul>
Bonus points for
<ul>
<li style="font-weight: 400;">Experience working in open-source or maintainer-style engineering environments.</li>

<li style="font-weight: 400;">Experience helping take a product from zero to one in a startup or new product initiative.</li>

What success looks like
Success in this role means helping Thunderbolt make the leap from promising R&amp;D-stage product to a production-ready, enterprise-grade open-source AI product that security-conscious organizations can deploy with confidence. Within the first year, the Senior Engineering Manager should help turn a fast-moving early product into a team and engineering system that can scale by helping the team:
<ul>
<li style="font-weight: 400;">Define what “production-ready” means for Thunderbolt and consistently meet that bar.</li>
<li style="font-weight: 400;">Create the clarity, ownership, and release confidence the team needs to ship quickly and sustainably.</li>
<li style="font-weight: 400;">Raise the quality of the user-facing product experience while protecting codebase health, maintainability, privacy, and security.</li>
<li style="font-weight: 400;">Build the lightweight structure needed for a senior team to do its best work without slowing down experimentation.</li>
<li style="font-weight: 400;">Help build Thunderbolt for global scale, enterprise adoption, and real-world impact!</li>

Release Engineer

MZLA Technologies Corporation (MZLA) is a wholly owned, for-profit subsidiary of the Mozilla Foundation and home to Thunderbird, our flagship open-source email and productivity platform empowering more than 20 million people around the world. While part of the Mozilla portfolio of companies, MZLA operates independently in both identity and organizational structure from the Mozilla Foundation and Mozilla Corporation. Everything we build at MZLA is open source, developed transparently and in collaboration with a global community of contributors. This open approach shapes not only our products but also how we work: collaboratively, inclusively, and with a shared commitment to building technology that puts users first. We believe privacy and productivity should coexist, and that people deserve powerful digital tools without surrendering control of their data. MZLA is a small but growing team of 50+ people distributed across seven countries. As we evolve Thunderbird from a single application into a suite of privacy-respecting productivity tools, we’re introducing new products and services that remain independent of big tech ecosystems. Our unique revenue model combines community donations that keep Thunderbird freely available with subscriptions for new cloud-based services, allowing us to grow and innovate while remaining independent and true to our values.

This team operates at the intersection of engineering, infrastructure, and product delivery, strengthening our automation systems and enabling developers to ship with confidence. Because Thunderbird shares upstream technologies with Firefox, you will collaborate across the broader Mozilla ecosystem to adapt and integrate build system changes into Thunderbird’s release pipeline. What you’ll do:&nbsp; Develop and maintain workflows for automating software builds and releases, including managing dependencies and toolchains. Write and enhance CI / CD workflows, packaging, and installation scripts for Thunderbird on Linux, Windows, macOS, Android, and iOS platforms. Adapt changes to build scripts made by the Firefox engineering teams to Thunderbird. Identify, troubleshoot, and resolve complex build, test, and dependency issues in collaboration with developers and contributors. Participate in process improvement initiatives, contribute to the evaluation and design of alternative solutions, and support ad hoc projects as required. Ensure the timely and high-quality delivery of Thunderbird releases. Engage with the open-source community to gather feedback, address concerns, and foster collaboration. What you’ll bring:&nbsp; 3+ years of professional experience, including build and release engineering for applications on Linux, Windows, macOS, Android, and iOS platforms.
