Backend Tech Lead, XP Platform

We're looking for a Backend Tech Lead to help shape the technical foundation of Lemonade's customer experience platform. This role sits at the heart of how millions of users interact with our products - owning the architecture of our client-facing domains, and setting the bar for backend engineering across the XP Platform group.

You'll be the kind of engineer other engineers look to when things get complex. Someone who's built systems at scale, led cross-team initiatives, and knows what it takes to go from whiteboard to production without losing the details along the way.

We believe three things matter for every role at Lemonade: drive to push through challenges, efficiency that keeps standards high while moving fast, and adaptability that lets you pivot with data and AI insights. These aren't buzzwords, they're how we actually work.

Our AI-first approach isn't just a tagline either. We're building the future of insurance with AI at the center, and we need people who are genuinely excited to learn and grow alongside these tools.

In this role you'll

• Own your domain end-to-end - driving code quality, performance, and scalability

• Lead architecture decisions for platform-level features, from planning and design through to production

• Build backend services using TypeScript and NestJS running on Kubernetes, with a focus on reliability and scale

• Coach and mentor backend engineers across XP Platform, helping them level up their architecture and coding skills

• Drive cross-squad initiatives, partnering with engineering managers, product, FE tech leads, UX designers, and senior engineers to get things done

• Leverage in-house autonomous tools to manage the full development flow - from environment setup to deployment

• Bring features to the finish line by aligning stakeholders across product, design, and data

What you'll need

• 6+ years of backend engineering experience - with at least 2 years of experience as a Tech Lead or a similar role, with a track record of building and scaling high-traffic, production-grade systems

• Proficiency in TypeScript and NestJS

• Deep familiarity with modern backend frameworks, tools, and distributed architecture - you know the tradeoffs and can make the call

• Experience leading engineers through a shared project, with real ownership over their direction and success

• Strong communication skills

• B.S. in Computer Science or Mathematics, or equivalent hands-on experience

• Ability to work in an office environment most days of the week

• Enthusiasm about learning and adapting to the exciting world of AI – a commitment to exploring this field is a fundamental part of our culture
