At iwell, we are all about reinforcing energy security. We help European businesses become more energy independent. Because with growing regulations, extreme price volatility and rising grid issues, they just need to be resilient. So it's time to take charge and think ahead. We deliver energy management solutions that ensure businesses are always in control of their energy. Our in-house developed EMS and modular battery storage, drive profit through sustainability, making businesses future-proof. We’re a fast-growing international team of bold, talented individuals. From engineers and software developers to creative thinkers and customer-focused business developers, we are looking for people who are determined to make a positive impact.

The Role

Our mission is to optimize local energy usage by delivering smart, flexible, and reliable battery energy storage solutions. As a Software Support Engineer (third line), you’ll play a key role in ensuring the stability and reliability of the software that powers our battery systems, directly contributing to a more sustainable future. You’ll join the CubeEms team, responsible for the entire software stack on our battery systems, from low-level control to high-level interfaces. You’ll work closely with the operations team and software developers to troubleshoot and resolve complex, real-world issues. This means digging into bugs and edge cases, using your strong C# skills to identify and fix root causes. You’ll also help improve our tooling and documentation to make problem-solving faster and more effective. To be effective, you'll need to keep a cool head while juggling multiple requests, communicate clearly with both technical and non-technical colleagues, and bring a structured, calm approach to debugging. This is a high-impact role where your fixes and insights will be immediately felt by our customers and partners. If you enjoy deep technical challenges and want your work to support the energy transition — we’d love to hear from you.
