About the Role Join a fast-moving energy technology company building the operating system for the next generation of energy in Europe. This role sits on the core infrastructure team , where you'll architect and scale systems that power modular billing engines, low-level energy-market communication protocols, and full accounting ledgers. If you're energised by deep technical complexity and want your work to have a direct impact on European households and energy markets, this is the role for you. What You'll Do Solve for complexity through design — tackle hard architectural problems and design systems that remain clean and maintainable as they scale. Scale the core — build and evolve the backbone infrastructure that supports dynamic electricity plans and reliable billing at scale.
