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.
