React Native App Developer

About the job

We’re Deftpower, and we’re fixing the backend of electric driving to pave the way for a smarter way to support our energy grid.

That might sound unglamorous, but it’s essential work: making EV charging work smoothly across different networks, apps, and countries. With that fundament in place, we are on pole position for realizing Europe's biggest virtual power plant, consisting of the connected vehicles of EV-drivers that use the platform. With it, we make sure the energy grid is ready for the energy transition by charging these vehicles at the optimal moments, without hindering the driver. One way we help? We build a premium white-label mobile app for EV charging — and that’s where you come in.

We’re looking for a React Native developer to join our growing app team (currently 3 app devs, 2 backend devs and 2 UX/UI designers). Together, you’ll work on the best-looking and most flexible EV charging app on the market — a on average 4.7 star rated product our customers can truly make their own.

What you will do

• Build and improve our white-label React Native app used by tens of thousands of EV drivers.

• Develop new features that enhance price transparency, finding the right charging locations or the charging experience itself.

• Help our customers make the app their own — either through config or by plugging in custom components via our SDK.

• Make sure every version looks and feels like one cohesive, polished app — even when 40+ different versions are live in the app stores.

• Work closely with backend developers, product owners, and designers to deliver smart, elegant new features.

• Think about performance, architecture, and automation — not just pixels.

The app you’ll work on

Is built in React Native and published to iOS and Android through a fully automated build and release pipeline. Customers can configure the app extensively — layout, colors, feature toggles — or use our SDK to inject their own React Native components at build time. This makes the app flexible without becoming a wild west of inconsistent UX. It also keeps the product scalable and well-maintainable.

About you

• You have a few years of hands-on React Native experience, and can comfortably ship features from idea to store.

• You understand the mobile platform differences (iOS/Android) and how to manage them sensibly in a single codebase.

• You’re pragmatic, clean in your code, and don’t shy away from good discussions.

• You like being part of a team that builds and ships things together — not in silos.

• You have experience with native iOS/Android development as well.

Bonus points if you...

• Have worked on white-label or multi-tenant apps before.

• Can take the lead in profiling, debugging or fine-tuning the nitty gritty details of the React Native app.

• Know your way around build automation and CI/CD pipelines.

• Are excited about the EV world (or already drive one 🚗⚡).
