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.

Perks

• Super small team, super early → you're not only part of our culture, you will shape it

• Responsibility from day one → the best idea wins, regardless of who it comes from

• All the tools you need → Cursor, AI subscriptions, whatever helps you ship faster

• Direct customer access → build what matters, see impact immediately

• Munich-based → work alongside founders solving hard problems together

• €70-100K salary + equity as Full Time

• €20/h as working student
