C#/.NET Backend Developer - eMobility (SaaS)

At Deftpower we're looking for a C#/.NET Backend Developer to join our team.

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.

Our Tech Stack

The Deftpower platform 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. Data storage is done in a variety of ways, but Cosmos and Azure SQL databases are used most. Monitoring and logging is done with Application Insights and Grafana as well as PowerBI dashboards. The portal that interacts with the backend is written in Angular, while our mobile applications are developed in React Native. In general, we use Azure's PaaS components wherever possible to stay up to date and ready for scale.

About The Job

As Backend Developer at Deftpower you co-develop the SaaS platform that powers the future of smart charging. You join the Smart Charging team, where you solve puzzles that have never been solved before and bring your own ideas to the product. What makes this role different is our way of working: with Shape Up cycles of six weeks you get focus, ownership and the chance to deliver something concrete every time! Thanks to great collaboration, the team is very close-knit and strong. Joining one of the regular team activities will be highly appreciated!
