Senior Backend Engineer — Trading & Asset Optimization

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.

What you'll do

• Design and build the backend systems behind our trading and asset-optimization platform. The services, data flows, and logic that need to be both fast and dependable.
• Own initiatives end to end: gathering requirements with product and trading colleagues, shaping the approach, and rolling it out iteratively.
• Work 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, including our data scientists and quantitative traders.
• Raise the bar on quality, observability, and how we reason about correctness in a system where mistakes are expensive.
• Operate and maintain what we build. We stay with our systems after launch: keeping them healthy in production, learning from how they behave, and improving them over time.

What you'll need

• Built complex, data-intensive systems and can point to projects you're proud of.
• Owned a large initiative end-to-end. From fuzzy requirements through an iterative rollout to production - not just the code, but the outcome.
• Put the team first: you genuinely enjoy collaborating with people around you and you'd rather support the team than be the lone hero.
• Comfortable making architectural decisions in an evolving codebase.
• Drawn to hard, meaningful problems and want to help shape the next steps of an energy trading and asset-optimization platform.

Nice to have

• 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.

What they offer

• Real impact on one of Europe's fastest-growing B2B energy platforms at a pivotal moment.
• Early ownership and responsibility from day one with direct shipping opportunities.
• Mentorship that matters with regular leadership sessions and cross-functional exposure.
• Annual learning budget and dedicated development time.
• Family-friendly policies and inclusive workplace with 15+ nationalities.
• Competitive benefits package covering wellbeing, learning, and team experiences.
