We also have a web portal that is written in Angular.

• Take over native development that currently runs through an external partner, so this expertise lives inside the team going forward

• Keep certificates, store requirements and native release steps for iOS and Android running smoothly

• Coach and pair with your React Native colleagues whenever they run into native quirks

• Work closely with Linda as Team Lead, plus Product and Design, to turn native roadmap items into real features people use

About you

• You've got 5+ years of experience in mobile development, with real, hands on experience in both native iOS and native Android. You don't just write native code, you also know how to make it play nice with a React Native app around it.

• You're strong in both Swift and Kotlin, iOS and Android matter equally here

• You've worked in or alongside a React Native codebase before, so bridging native modules isn't new territory

• You take real ownership of native features, from Live Activities to CarPlay and Android Auto

• You're comfortable being the specialist in a team full of generalists, and you don't mind explaining native quirks to people who mostly think in React Native
