We're building the Experience Platform that powers everything at Lemonade - the backbone that lets our teams ship fast, scale seamlessly, and focus on creating incredible experiences for millions of customers. As a Senior Backend Engineer, you'll architect solutions that make other developers' lives easier while pushing platform boundaries. You'll own our chat service that handles onboarding flows for every Lemonade customer.

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 platform services that let product teams ship features in days, not weeks

• Build TypeScript/NestJS microservices that handle millions of customer interactions on Kubernetes

• Partner with product teams to deliver the infrastructure they need to move fast

• Level up our development experience using autonomous tools that handle everything from environment setup to production deploys

• Lead architectural decisions that impact how we build, deploy, and scale products company-wide

• Collaborate across product, design, and data teams to bring complex features from concept to launch

• Drive platform reliability improvements that directly impact customer experience

WHAT YOU'LL NEED:

• 5+ years building backend systems that other engineers depend on daily

• Deep understanding of modern backend architecture, microservices, and distributed systems

• Experience leading technical projects and mentoring other engineers

• Strong foundation in computer science fundamentals (degree or equivalent experience)

• TypeScript and NestJS experience strongly preferred

• Ready to work in an office environment most days a 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
