Founding Engineer
Visa sponsorship: Available
Founding engineer at a cleantech startup building AI software for battery storage optimization, requiring full-stack skills and German fluency.
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
Must-haves (dealbreakers)
- 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.
COMPENSATION & BENEFITS
- Salary: $70,000 – $100,000 annually
- Visa sponsorship: Available
- Founding-stage equity and direct impact on company trajectory
