App Developer (React Native) - eMobility (SaaS)
About Deftpower
At Deftpower, we’re shaping the future of electric charging every single day. Our SaaS-platform helps businesses across Europe make charging simpler, smarter, and more sustainable. With AI and intelligent software, we make sure charging works seamlessly with the energy grid, creating a greener and more stable system for everyone.
We’re growing fast, thanks to a recent major investment, and there’s never a dull moment! We’re expanding, improving our technology and teaming up with companies in over ten countries.
About the team
You join the App team, where the team builds in React Native. The app is the part EV drivers actually hold in their hands: finding a charger, starting a session, following it live and seeing what it cost. You’ll work closely with Linda, our PO, and Jason, our App Team Lead.
We work in cycles using Shape Up, which we call Heartbeat. Each cycle, small cross-team squads form around a shaped project with a fixed appetite, for example an app developer, a backend developer and a designer working on a feature end to end. The squad decides how to solve the problem and ships it within the cycle, so you’re not waiting on handovers between teams.
Our Tech Stack
The app is written in React Native with some native modules written in Swift & Kotlin. Our backend is built in C#/.NET. We are heavily using Azure Functions to keep our platform as scalable as possible. We adopt a microservice architecture where services communicate with each other mainly via the Azure Service Bus. We also have a web portal that is written in Angular.
“Everyone is driven to make customers happy, we don't just work for the sake of working.”
- Florian, Team Lead
