About us

At Zego, we know that traditional motor insurance holds good drivers back. It’s too complicated, too expensive, and it doesn't take into account how well you actually drive. 

That’s why, since 2016, we’ve been on a mission to change all of that. Our mission at Zego is to offer the lowest priced insurance for good drivers.

From van drivers and gig workers to everyday car drivers, our customers are our driving force — they’re at the heart of everything we do.

We’ve sold tens of millions of policies so far, and raised over $200 million in funding. And we’re only just getting started.

About the role

We’re looking for a Lead Frontend Engineer to lead the next generation of digital experiences at Zego. You’ll join a high-impact B2C product team and take ownership of building and scaling intuitive, performant, and inclusive user interfaces.

This is more than just a senior engineering role, you’ll act as a technical lead within your team. You’ll shape architecture, coach engineers, and help us move from a legacy monolith to a micro-frontends ecosystem powered by React, Next.js, and a BFF pattern.

What you will be doing

• Drive frontend strategy in an environment where quality, usability and reliability matter.

• Lead development of scalable and accessible front-end products using React, Next.js, and TypeScript.
  
  
• Architect user journeys that power onboarding, quoting, and policy management for thousands of drivers.
  
• Contribute to backend services connected to the frontend

• Drive consistency, speed, and reliability in our front-end by shaping our design, improving performance, and ensuring we can monitor and debug issues effectively.
  
  
• Partner with product and design to rapidly test ideas, validate hypotheses, and ship iteratively.
  
  
• Mentor other engineers through code reviews, pair programming, and continuous feedback.
  
  
• Improve CI/CD workflows and automate test coverage for rapid, safe deployments.
  
  
• Take ownership of cross-team initiatives and lead conversations across frontend and backend boundaries

• Embrace AI tools and workflows to accelerate development and improve quality.
  
  

About you

• You bring full-stack experience but focus your expertise on frontend development. You're confident working across the stack when needed, including diving into backend code and making sense of the wider architecture

• You have experience leading a team of multiple Front End Engineers working on a technically complex problem space.

• You’re passionate about crafting seamless digital experiences that are accessible and delightful.
  
  
• You bring commercial experience with React and Next.js or similar modern frameworks in production, ideally with GraphQL, gRPC and REST.
  
  
• You care about writing clean, tested, maintainable code and know when to optimise.
  
  
• You’ve taken products through the full lifecycle from discovery through to scale.
  
  
• You lead by example and bring others with you, through mentorship and collaboration.
  
  
• You’re tenacious and resourceful, able to find a way through difficult problems and make progress in ambiguous situations. You consistently bring a pragmatic mindset to engineering challenges and lean toward simplicity and maintainability over over-engineering.
  
  
• You’re proactive by nature. You spot issues before they become blockers, and you take ownership- raising them early, bringing the right people into the conversation, and helping the team find the right path forward.
  
  
• You have experience designing and implementing automated testing from scratch, and you’re confident in shaping the testing strategy for a codebase. You take ownership of quality and help ensure we ship reliable, predictable front-end experiences.

• You will be someone who’s actively curious about how AI can enhance your work - keen to experiment, learn quickly, and apply tools that improve productivity, streamline tasks, or unlock new ways of thinking. Whether you’re already hands-on or fast building confidence, you take ownership of staying ahead and working smarter
