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
