Job description

Gravitas Recruitment Group (Global) Ltd provided pay range

This range is provided by Gravitas Recruitment Group (Global) Ltd. Your actual pay will be based on your skills and experience — talk with your recruiter to learn more.

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

Seniority level

• Mid‑Senior level

Employment type

• Full‑time
