About the role
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

Strong full-stack engineering fundamentals
Math/optimization skills highly valued
Excited about complex technical challenges
Mission-driven
Passionate about energy transition and climate impact

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.
