Base pay range

This is an opportunity to join a high-traffic consumer product used by millions of people every month, where mobile is a core part of the experience rather than an afterthought.

You’ll be joining an established engineering function with 25+ engineers in the UK (50+ globally), working on iOS and Android apps that see millions of active users and real‑world impact every single day.

The mission is simple but ambitious: build a mobile app that users genuinely trust, return to daily, and rely on to make better purchasing decisions. You’ll play a key role in shaping how that experience looks, feels and evolves.

This role suits someone who cares deeply about product quality, enjoys ownership, and wants to work on a mature app where engineering standards matter.

What you’ll be doing

  • Owning the development of production iOS and Android apps built with React Native
  • Working closely with product managers, designers and fellow engineers to turn ideas into polished, user‑loved features
  • Building high‑quality, delightful mobile experiences, including animations and micro‑interactions
  • Taking responsibility for code quality, testing and release readiness
  • Improving and maintaining a robust CI/CD pipeline and strong engineering standards
  • Helping the wider team move faster by unblocking problems and raising the technical bar
  • Keeping up with modern mobile tooling and best practices, and applying them pragmatically
  • Providing technical guidance and mentorship to other engineers

What they’re looking for

  • 5+ years of commercial React Native experience
  • Strong understanding of the React Native ecosystem, performance, builds and native integrations
  • Proven ability to translate designs into pixel‑perfect, smooth user experiences
  • Experience with modern tooling such as Expo, CI/CD pipelines, monorepos and cloud infrastructure
  • Solid understanding of how frontend, backend and networks interact
  • Comfortable taking technical ownership and influencing standards
  • Clear communicator with a delivery‑focused mindset
  • Experience using modern developer tools (including AI/LLM tooling) is a bonus, not a requirement

Working environment

  • Hybrid working with flexibility — no expectation to be in the office every day
  • Modern, well‑located London office with great food, coffee and social spots nearby
  • Collaborative, inclusive culture that values balance as much as delivery
  • Real autonomy and trust — you’ll be treated like a senior, not micromanaged
  • Generous pension with employer contributions up to 8%
  • Private medical insurance
  • Subsidised gym membership
  • Employee Assistance Programme
  • Free lunch when you’re in the office
  • Dedicated weekly time for personal development
  • Enhanced parental leave and strong support for returning parents
  • Paid volunteering time plus donation matching
  • Regular social events and company‑wide recognition programmes

  • Mid‑Senior level
