Are you passionate about building the technical backbone of the energy transition? Join suena energy as Senior Backend Engineer (f/m/x) and become a founding member of our newly formed Platform team. You'll help design and build the API and integration layer that connects our trading, analytics, and optimization systems — and in doing so, directly shape how clean energy is managed across European power markets.
suena energy is a green tech startup specializing in algorithmic energy trading for battery storage systems and renewables.
Our vision: a world where clean energy is used reliably, economically, and intelligently. With our AI-based optimization and trading software, we maximize the revenues of operators of large-scale energy storage and renewable assets on short-term electricity and balancing markets - while simultaneously minimizing their risks.
We're a team of 50+ people, combining a warm, supportive culture with real startup drive. Following our successful Series A, we're now building a dedicated Platform team from scratch.

A note on applications
As part of your application, we'd love to see a Python project you're genuinely proud of — production code, a side project, a study case, anything goes. It doesn't need to be polished. We'll use it as the basis for a technical conversation: what decisions did you make, why, what would you do differently? Send us the link of your repository. Be sure we have access.
If you don't have something ready to share, no problem — we'll send you a small, focused task instead.
Not quite senior level yet, but this role sounds like the direction you're heading? Apply anyway and let us know — we're also building out the junior side of the team.
We look forward to receiving your application, earliest start is as soon as possible. If you have any questions, feel free to reach out - your contact is Kathi (Interim Talent Partner).
You’ll hear back from us within 5 working days of your application. We value your time and want to make the process as transparent as possible. Once we receive your application, we’ll send you a confirmation email outlining the next steps and what you can expect from our interview process.
We can’t wait to meet you!
