Founding Engineer

Role details

ABOUT THE ROLE This is a hands-on founding engineering role at an early-stage energy software startup building an end-to-end platform for industrial battery storage. You'll own both backend and frontend development, shaping the core product that drives real-time optimization and forecasting across a growing portfolio of energy assets. Your work will have direct impact on product direction and company trajectory. WHAT YOU'LL DO - Own and build the core product driving real-time optimization and forecasting for energy assets. - Develop backend services and optimization algorithms to process operational data in real time. - Create frontend dashboards for battery operators to monitor and control assets. - Design and scale infrastructure to support thousands of battery systems. - Collaborate cross-functionally to define product features and requirements. - Deploy production-ready optimizations and iterate based on live deployment feedback. WHAT WE'RE LOOKING FOR - Full-stack engineering experience (2–6 years) building and shipping production applications. - Startup experience at an early-stage company (under 3 years old and fewer than 50 employees). - Strong frontend skills with JavaScript/TypeScript, React (Next.js preferred), and Tailwind CSS. - Solid backend experience with Python, including mixed-integer optimization techniques. - Hands-on experience with real-time data processing and optimization/forecasting systems. - Experience designing and operating scalable distributed backend systems. - Containerization and modern deployment practices (Docker/Kubernetes) with CI/CD pipelines. - Familiarity with observability and monitoring tools (e.g., Prometheus, Grafana, OpenTelemetry). - Database design and data modeling experience (e.g., PostgreSQL/MySQL). - Cloud infrastructure experience (AWS, GCP, or Azure). - Bachelor's or Master's degree in Computer Science, Mathematics, or Electrical Engineering with strong academic performance. - Fluency in German is highly valued — most customers operate in German-speaking markets. - Experience in the energy industry or deploying optimizations in production systems is a plus. COMPENSATION & BENEFITS Salary range: €70,000 – €100,000 annually. Visa sponsorship is available. LOCATION On-site in Munich, Germany.
