Backend Engineer
Willingness to work on-site in Berlin, Germany
Backend engineer for an energy tech company building a billing and market communication platform.
ABOUT THE ROLE
Join the core infrastructure team of a fast-growing energy technology company building the operating system for the next generation of European energy. The platform combines a modular billing engine, low-level energy-market communication protocols, and a full accounting ledger — delivered as a headless, API-first layer that enables hardware companies and energy providers to launch dynamic electricity plans rapidly.
As a Backend Engineer, you will work across highly complex, distributed systems that power real-time electricity pricing, billing, and market integrations. This is a high-ownership role for engineers who love designing for scale and operating with autonomy in a fast-moving environment.
WHAT YOU'LL DO
- Solve for complexity through design — Architect clean, maintainable solutions to inherently hard infrastructure problems in energy billing and market communication.
- Scale the core — Contribute to scalable, reliable backend services that handle dynamic pricing, billing flows, and ledger operations at volume.
- Bias for action — Move quickly and decisively; ship meaningful work and iterate with purpose.
- Raise the bar — Uphold and improve engineering standards through code review, documentation, and thoughtful system design.
