Founding Engineer

You'll build the core product that controls billions in energy assets:

Backend systems for real-time optimization and forecasting

Frontend for battery operators and industrial customers

Infrastructure to scale across thousands of battery systems

You Will Have Fun If You Are

Builder with agency

Get-shit-done mentality — you ship fast and iterate

High ownership — you develop ideas and execute with minimal guidance

Product-minded — you solve customer problems end-to-end

Deeply technical

Strong full-stack engineering fundamentals

Math/optimization skills highly valued

Excited about complex technical challenges

Mission-driven

Passionate about energy transition and climate impact

Thrive in early-stage chaos and ambiguity (e.g. "What about a release today?")

Ready to go all in and take real ownership

You Won't Have Fun If You

Like to follow processes — we don't have any

Want a typical 9-5

Want to work remotely — we're in the office at least 5 days/week

Like coding all day long — at least 20% of your work is talking to customers

Qualifications

Experience in a full-stack engineering role, building production applications

Frontend development skills with JavaScript/TypeScript, React (preferably with Next.js), and Tailwind CSS

Solid backend development experience with Python and mixed integer optimizations

Experience with cloud infrastructure (AWS/GCP/Azure)

Speak fluently German because most of our customers only speak German

Don't worry if you don't have all of the above. We believe much more in the right mindset than the right experience. We happily teach you a lot and thus prefer fast-learners over high experience.
