Forward Deployed Hardware Engineer

Our software decides every 15 minutes what a battery should do. You make sure it actually does it: - Integrate our optimizer with battery controllers over Modbus, MQTT and vendor APIs - Commission systems on site until the battery follows the plan to the kW - Build our own edge box on standard hardware (think Raspberry Pi on a DIN rail) YOU WILL HAVE FUN IF YOU ARE Builder with agency - Get-shit-done mentality: you'd rather drive to the site than wait for a support ticket - High ownership, from the vendor call to go-live Mission-driven - Passionate about energy transition and climate impact - Thrive in early-stage chaos (e.g. "Can you be in Ingolstadt tomorrow at 8?") YOU WON'T HAVE FUN IF YOU - Like to follow processes. We don't have any. - Want to work remotely. We're in the office 5 days/week, and regularly on site at customers. - Want to stay on one side of the wall. This is half software, half hardware. QUALIFICATIONS - Solid Python and embedded Linux (networking, VPN, remote updates) - Industrial protocols: Modbus TCP/RTU, MQTT, REST - Electrical basics: inverter, BMS, grid connection point. Bonus: PV/battery commissioning - Fluent German, because installers and customers speak German Don't worry if you don't have all of the above. We prefer fast learners over high experience. PERKS - Super small team, super early: you shape the culture - You define the hardware: which box we ship and how it's built is your call - Direct customer access: see your code move a megawatt-hour battery - €70–100K salary + equity as full time · €24/h as working student
