Founding Engineer

Join a small, ambitious team building the core software platform that controls and optimises industrial battery storage assets across Europe. As a Founding Engineer, you will have outsized ownership across the full stack - from real-time optimisation algorithms and backend services to operator-facing dashboards and cloud infrastructure. Your work will directly shape both the product and the trajectory of the company at a critical early stage., * Own and build the core product powering real-time optimisation and forecasting for industrial energy assets.

• Develop backend services and mixed-integer optimisation algorithms to process high-frequency data in real time.
• Design and scale distributed infrastructure to support thousands of battery systems in production.
• Build intuitive frontend dashboards that allow battery operators to monitor, control, and analyse their assets.
• Implement containerised, CI/CD-driven deployment pipelines and maintain production observability.
• Collaborate directly with founders and customers to define product features and translate operational requirements into engineering solutions.
• Iterate rapidly based on feedback from live deployments.

• Experience with real-time data processing and optimisation or forecasting systems.
• Proven ability to design and operate scalable distributed backend systems for large-scale deployments.
• Solid Python backend development skills, including mixed-integer optimisation.
• Frontend development proficiency with JavaScript/TypeScript and React (Next.js preferred); experience with Tailwind CSS.
• Containerisation and modern deployment practices - Docker, Kubernetes, and CI/CD for production services.
• Experience with observability and monitoring tooling (e.g. Prometheus, Grafana, OpenTelemetry).
• Database design and data modelling experience (e.g. PostgreSQL or MySQL).
• Cloud infrastructure experience with AWS, GCP, or Azure.
• Startup experience (company under 3 years old and fewer than 50 employees qualifies).
• Bachelor’s or Master’s degree in Computer Science, Mathematics, or Electrical Engineering with a grade better than 2.0 (German grading scale).
• Fluency in German - the majority of customers communicate in German.

Nice to Have:

• Background or hands-on experience in the energy industry (battery storage, renewables, grid management, or similar).
• Demonstrated track record of deploying optimisations in live production systems.

• Salary: €70,000 - €100,000 per year, depending on experience.
• Founding-stage equity and meaningful ownership in the company’s success.
• High-impact role with direct influence over product and company direction.
• Visa sponsorship available for qualified candidates.
