About this role
Our batteries fly. Literally. Every cell pack that leaves Den Bosch ends up on a drone or an electric aircraft, tested to survive vibration, thermal extremes, and real operational conditions at altitude. We design and manufacture high-density silicon-anode battery systems delivering 450 Wh/kg and 30–100% more flight time than conventional alternatives. MoD funding secured, TU Delft and NLR as partners, and manufacturing entirely in-house. Now we build. Why this role matters Electronics is what makes energy usable. The BMS circuits, PCBs, and power distribution logic you design determine whether a drone completes its mission or doesn't. You own the electronics chain from first requirement to production handover. You'll work closely with our mechanical team, firmware team, and manufacturing floor, but the electronics stack is yours. What you will own Define electronics requirements from scratch: work with customers and internal stakeholders to translate system-level needs into clear, testable specifications before a single schematic is drawn. Design and develop BMS circuits, PCBs, and electrical schematics in Altium Designer, covering power path, signal integrity, and thermal management. Prototype and solder boards yourself: power analyser, JTAG, and soldering iron are your daily instruments. Validate electronics under real conditions: thermal cycling, vibration, and electrical stress testing across the full operating range. Optimize for energy density, cell balancing, and power distribution across the pack. Ensure compliance with drone and aviation standards (CE, IEC, UN38.3), and own the documentation that gets a system certified. Work directly with mechanical, manufacturing, and firmware teams on system integration: your PCB must fit the enclosure, survive the vibration profile, and communicate with the firmware team. Document test results, specifications, and design decisions that future engineers can build on.
