That’s where our cloud platform comes in. We’re looking for a Full Stack Developer with a passion for turning complex systems into seamless, smart, and user-friendly solutions.Imagine this: you make a change to our cloud environment on Monday morning, and by the afternoon, our engineers, partners, and customers are already reaping the benefits.

You’ll play a key role in transitioning knowledge from external experts to our in-house team, ensuring that we own and shape the future of our cloud technology. As we shift from embedded battery solutions to smart, cloud-connected energy ecosystems, your fingerprints will be all over the next chapter of innovation. No day is the same. One day you might be fixing bugs or polishing the UX of our web platform. The next, you’re adding a powerful new feature or ensuring our infrastructure scales smoothly for the future. You’ll be working closely with a highly engaged team of developers (mainly external) and collaborating with software engineers, designers, and stakeholders to bring big ass ideas to life. And who knows in the future you'll even grow the team. We believe in Agile principles – not as buzzwords, but as a way to keep energy flowing, deadlines realistic, and creativity alive. This role isn’t just about writing code – it’s about laying the foundations for the future of battery management. We want someone who can help us achieve new levels of stability and scalability, while also being a voice of communication and collaboration.
