Founding Engineer

ABOUT THE ROLE This is a founding engineering role at an early-stage industrial energy software company building an end-to-end platform that controls and optimises large-scale battery storage assets. You'll have a direct hand in shaping product and architecture at a critical stage of the company's growth, working across the full stack to deliver real-world impact on how European industry manages energy costs. WHAT YOU'LL DO - Own and build core backend services that power real-time optimisation and forecasting for industrial battery systems. - Develop and deploy mixed-integer optimisation algorithms that process data in real time. - Build frontend dashboards enabling battery operators to monitor and control their assets. - Design and scale distributed infrastructure to support deployments across thousands of battery systems. - Collaborate cross-functionally to define and iterate on product features based on real deployment feedback. WHAT WE'RE LOOKING FOR - Fluent or near-fluent German — a hard requirement, as the primary customer base is German-speaking. - Bachelor's or Master's degree in Computer Science, Mathematics, or Electrical Engineering with strong academic results (GPA equivalent better than 2.0 on the German scale). - Experience at an early-stage startup (small team, early years of operation). - Full-stack engineering experience building and shipping production applications. - Frontend proficiency with TypeScript/JavaScript, React (Next.js preferred), and Tailwind CSS. - Strong backend development skills in Python, including experience with optimisation or forecasting systems. - Hands-on experience designing and operating scalable distributed backend systems. - Solid understanding of database design and data modelling (e.g. PostgreSQL or MySQL). - Containerisation and modern deployment practices — Docker, Kubernetes, and CI/CD pipelines for production services. - Experience with observability and monitoring tooling (e.g. Prometheus, Grafana, OpenTelemetry). - Cloud infrastructure experience across one or more of AWS, GCP, or Azure. - Prior experience in the energy industry and/or deployed optimisations in production systems is a plus. COMPENSATION & BENEFITS - Salary: €70,000 – €100,000 per year - Visa sponsorship: Available LOCATION On-site in Munich, Bavaria, Germany.
