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
