Senior React Native Mobile Engineer

We are looking for a senior React Native engineer who can join an existing product team and take real ownership of a live mobile application during a six-month remote contractor engagement. This is not a role for someone who only ports web screens onto a phone. It is for an engineer who already ships production React Native with judgement, cares about how the app feels in the hand, and can work inside an established codebase without waiting to be told what matters. You will help deliver a substantial update to an application that already has users, design partners, and a web counterpart. That means collaborating with product, design, and engineering to refine scope, break work into sprint-ready slices, and keep delivery honest. You will write TypeScript-first React Native that is reusable, testable, and maintainable, and you will treat performance, accessibility, and release hygiene as part of the design, not a polish pass at the end. The work sits close to the web team’s standards: design systems and component libraries used with discipline, REST APIs integrated cleanly, and automated testing that the team intends to grow. On mobile that also means platform differences you do not paper over. You should be comfortable with the React Native bridge and the newer architecture where it is in play, with native modules when JavaScript is the wrong layer, and with the unglamorous work of certificates, store listings, crash reporting, and incremental rollouts. The community already knows the difference between a React Native app that demos well and one that survives App Store review, OS upgrades, and a year of product change. We are hiring for the second kind. If you take pride in 60fps lists, accessible controls, predictable state, and a release train that does not frighten the business, this engagement is built to use that craft. If you want a six-month stretch of focused mobile work with designers and engineers who care about the same details, we would like to hear from you.
