Senior React Native Engineer
Full-time · Retail & Consumer Products
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
Expert-level TypeScript / JavaScript
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
Benefits:
Competitive salary
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
