Job Description

Job Description 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. Job Requirements Bachelor's in Electronics, Electrical Engineering, or equivalent field. 2–5 years of professional experience in PCB design and hardware development. Product development experience across the full lifecycle (concept, requirements, design, and test), ideally within a structured approach such as the V-model. A hands-on mentality with a proven track record in the lab using a multimeter, oscilloscope, or soldering iron. Strong Altium Designer skills: schematics, layout, BOM management. Experience with power electronics or BMS design in low-voltage systems. Familiarity with compliance standards: CE, IEC, UN38.3. Nice to have Experience taking a product all the way into production. EMC testing background. Drone, UAV, or aerospace hardware background. Interview process Intro call with Recruiter → Technical interview day with Hiring Manager + team (60 + 45 min, on-site) → Offer. What we offer 38 paid days off per year (25 vacation + 13 ADV via CAO Metaal & Techniek). 8% holiday allowance, travel reimbursement, and pension via PMT. Daily lunch provided by the company. Direct access to the full electronics chain: from first schematic to battery in the air. Flat team: your board-level decisions reach production fast. Ready to build something that matters? No agencies, please.

Core Responsibilities

Define testable electronics requirements and design BMS circuits, PCBs, and electrical schematics, taking ownership from initial requirements through production handover. Build and validate prototypes, optimize battery-pack electronics, ensure compliance and documentation, and integrate designs with mechanical, firmware, and manufacturing teams.

Requirements

Requires a bachelor's degree in Electronics, Electrical Engineering, or an equivalent field, plus 2–5 years of professional PCB design and hardware development experience. Candidates should have full-lifecycle product development experience, hands-on lab skills, strong Altium Designer skills, and experience with low-voltage power electronics or BMS design; familiarity with CE, IEC, and UN38.3 standards is also required.

Benefits

• 38 Paid Days Off
• 8% Holiday Allowance
• Travel Reimbursement
• Pension Through PMT
• Daily Company-Provided Lunch
