Senior Product Engineer, React Native

the team move faster, and learn from what others discover. Help shape AI in our product. AI features in our app are still early. Spot the customer moments where AI can create magic, prototype them, and bring them to life. Own delivery end-to-end. Pick up a problem, design the solution, ship the mobile work, write the backend code when the feature requires it, and see it through to production. Own on-call. Be on the rotation, and stand behind what you ship in production. Keep the app fast and trusted. Profile performance, harden release processes, and protect production health. Raise the bar for

the team. Contribute to architectural discussions and the patterns that shape our codebase. Lift the people around you. You're a great fit if you Mobile experience. 5+ years building production software. Deep React Native and Expo. Strong across iOS and Android, with B2C apps in your track record. Strong fundamentals. Confident and idiomatic in TypeScript. Use AI daily. AI assistants are part of how you build. You bring back patterns that help others get more out of them too. Think product, not just code. You measure your work by what changed for the customer, not the lines of code shipped. Production minded. Solid grasp of mobile performance, app stability, release processes, and mobile security. Care about craft. Design systems, attention to detail, and how the product feels. Comfortable in uncertainty. You move forward when the path isn't clear, instead of waiting for someone to define it. Test as you build. Automated tests are how you ship code you trust. Passionate about execution. Curiosity, energy, and a habit of moving things forward. Excellent communicator. Clear in how you write and speak, and you love sharing what you learn. If most of these land for you, please apply. We hire on trajectory and curiosity as much as CV. Even better if you know NestJS. Our backend is a NestJS service, and you'd feel at home when features need backend work. GraphQL. We run a federated gateway across multiple subgraphs, so federation experience makes schema and subgraph work easier. GCP and DevOps. Firestore, Pub/Sub, Cloud Run, Firebase. Native iOS or Android. Swift or Kotlin. We maintain a custom Expo native module for iOS Live Activities, which powers order tracking on the lock screen and Dynamic Island. React Native Web. Cross-platform delivery from a shared codebase. Quick commerce or similar domain. Logistics, on-demand delivery, or another real-time, high-throughput customer-facing environment. You won't be a great fit if you Need a fully defined process and a large, structured team to do your best work. Chase technical perfection at the expense of what the customer actually needs. Stall when the path forward isn't clear, or wait to be told what to do. Want to stay strictly inside your specialty and avoid unfamiliar parts of the stack. What's the interview process like? We aim to make our process clear, respectful of your time, and a real two-way conversation. Stage 1 - Intro call (30 min). A short chat about your background and a chance for us to tell you more about Zapp,

the team, and

the role. Stage 2 - Technical interview (90 min). Live coding with full access to any AI tooling you'd normally use, and we'll send you a boilerplate repository in advance so you can focus on the problem, not the setup. Stage 3 - On-site interview (2 hours, in person). A visit to our office: one hour of mobile architecture, and one hour with senior leadership on how you work, what you care about, and how you align with our Leadership Principles. Stage 4 - Offer. We verify your right to work in the UK and complete reference checks before the contract.
