Senior Backend Engineer, Autonomous Squad

What You’re Applying For

We're looking for a Senior Backend Engineer to help build the autonomous systems and internal platforms that power how Lemonade operates at scale. You'll be embedded in our engineering org, working across the stack to design and ship tools that make our tech teams faster, smarter, and more effective. This is a role with real ownership - from the first line of requirements to production and beyond.

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

• Build and scale microservices in TypeScript using NestJS, contributing to products used by a growing global customer base
• Design and implement internal tools and platforms tailored to the real needs of our engineering teams
• Research, evaluate, and integrate third-party tools - making sure they land smoothly and actually stick
• Partner with engineering, product, and operations teams to spot workflow inefficiencies and turn them into working solutions
• Own projects end-to-end - from scoping and design through development, deployment, and iteration
• Apply AI and LLM tooling within TypeScript-based frameworks to solve complex backend challenges in meaningful ways
• Set the bar for code quality, performance, and scalability across your domain
  
  

• 6+ years of backend engineering experience, with a strong grasp of modern frameworks and architecture
• Hands-on experience integrating LLMs and AI capabilities using TypeScript-native tooling and frameworks
• A track record of running projects autonomously and shipping high-quality results
• Experience building and maintaining high-scale, production-grade systems
• Strong communication skills and comfort working across diverse, cross-functional teams
• BSc in Computer Science or Mathematics, or equivalent practical experience
• Past contributions to open-source projects are a plus
• Ready to work in an office environment most days of the week
