About the Role

You'll join the team that owns energy trading and asset optimization at trawa, the engine that turns market signals and live asset data into smart, automated decisions. It's a data-intensive, high-stakes part of trawa's tech platform where good engineering directly moves the numbers that matter. We're looking for someone who loves building complex systems, takes real ownership of what they ship, and makes the people around them better. You'll shape architecture, drive initiatives end-to-end, and help define how the team builds.

Responsibilities

  • Designing and building the backend systems behind our trading and asset-optimization platform.
  • Owning initiatives end to end: gathering requirements with product and trading colleagues, shaping the approach, and rolling it out iteratively.
  • Working at the intersection of backend and data - modeling and moving data so it's reliable, explorable, and useful to the people who depend on it.
  • Raising the bar on quality, observability, and how we reason about correctness in a system where mistakes are expensive.
  • Operating and maintaining what we build.

Requirements

  • You've built complex, data-intensive systems and can point to projects you're proud of.
  • You've owned a large initiative end-to-end.
  • You put the team first: you genuinely enjoy collaborating with people around you.
  • You're comfortable making architectural decisions in an evolving codebase.
  • You're drawn to hard, meaningful problems and want to help shape the next steps of an energy trading and asset-optimization platform.
  • Experience at the intersection of backend and data engineering - building scalable data pipelines, modeling data to streamline it, and enabling data exploration for other functions.
  • Exposure to energy, trading, or other real-time, high-stakes domains.

About the Company

  • trawa is building the solution: the first integrated B2B energy platform that bundles procurement, energy management, and flexibility steering into one product.
  • We are the fastest-growing B2B energy platform in Europe — active in Germany and Austria today, expanding to a third market in 2027.
  • trawa is based in Berlin with ~100 FTE, ~30 of whom work in Product & Tech.
  • We have raised over €35M to date — including a €24M Series A in May 2025 — backed by Balderton, Headline, Speedinvest, AENU, Magnetic, and Tiny VC.
  • All three founders are on board and fully committed to building the utility of the future.
