Job description

ABOUT THE ROLE

This is a founding-stage full-stack engineering role at an early-stage B2B SaaS cleantech startup building AI-powered software that controls and optimizes industrial and commercial battery storage assets. The platform addresses real-world energy challenges — including volatile electricity prices and underutilized battery capacity — through strategies like self-consumption optimization, peak shaving, spot market arbitrage, and dynamic tariff management.

As a Founding Engineer, you will have an outsized impact on both product and company direction. You'll own core backend systems for real-time optimization and forecasting, build operator-facing dashboards, and architect the infrastructure needed to scale across thousands of battery systems.

WHAT YOU'LL DO

  • Own and build the core product driving real-time optimization and forecasting for energy assets.
  • Develop backend services and mixed-integer optimization algorithms to process data in real time.
  • Create intuitive frontend dashboards for battery operators to monitor and control assets.
  • Design and scale cloud infrastructure to support thousands of battery systems.
  • Collaborate cross-functionally to define product features and requirements.
  • Deploy production-ready optimizations and iterate rapidly based on real-world feedback.

WHAT WE'RE LOOKING FOR

  • Frontend development skills with JavaScript/TypeScript and React (Next.js preferred).
  • Proven experience in a full-stack engineering role building and shipping production applications. Required:
  • Experience with Tailwind CSS.
  • Degree in Computer Science, Mathematics, or Electrical Engineering (Bachelor's or Master's) with a strong academic record (grade better than 2.0 on the German scale).
  • Startup experience — defined as a company younger than 3 years and fewer than 50 employees.
  • Experience with cloud infrastructure (AWS, GCP, or Azure).
  • Solid Python backend development experience, including mixed-integer optimization.
  • Fluency in German — required, as the majority of customers operate in German.

Nice to have

  • Background or experience in the energy industry.
  • Experience deploying optimizations in production systems.
