Battery Technician/ Battery Engineer

We’re stepping outside our comfort zone!

Banks and Insurance Jobs is looking for a Battery Technician/Battery Engineer to join our client.

And just so you know, when we say we’re stepping outside our comfort zone, we really mean it. For once, our client isn’t a bank, insurance company, or other financial institution.

We’re excited to step into a new industry and connect the right talent with the right opportunity.

As our Battery Technician/Engineer, you are responsible for the physical assembly, configuration, and testing of our custom energy storage. You will spot-weld cells, integrate and wire advanced Battery Management Systems (BMS), and ensure our power packs are safely insulated to survive high-speed maneuvers and harsh saltwater environments.

Core tasks
Pack Assembly: Build high-performance Li-ion/LiFePO4 battery packs from the ground up, handling everything from cell sorting and spot welding to busbar integration and final enclosure.

BMS Configuration: Wire, configure, and tune Battery Management Systems to ensure perfect cell balancing, strict safety limits, and accurate State of Charge (SoC/SoH) reporting.

Testing & Quality Control: Run charge/discharge cycles, perform capacity testing, and aggressively debug power delivery issues down to the individual cell level before the pack ever sees the water.

Safety & Insulation: Apply potting, thermal interfaces, and physical thermal runaway prevention measures to ensure packs are completely vibration-proof and marine-ready.

Field Testing & Maintenance: Take your power stacks to the water. You’ll be on-site in Valkenburg and out at sea, swapping packs, monitoring real-time performance, and executing field repairs in real-world conditions.

Requirements
Education: Technical degree or vocational training (e.g., MBO/HBO or equivalent) in Electrical Engineering, Mechatronics, Automotive technology, or a related field.

Experience: Proven hands-on experience building custom battery packs (e.g., Electric Vehicles, Drones, Formula Student, or e-bikes/marine applications).

Technical Stack: – Expertise in safe battery assembly techniques (spot welding, soldering heavy-gauge wire, working with busbars). – Direct experience wiring and configuring BMS parameters. – Familiarity with basic diagnostic tools and communication protocols (CANbus). – Knowledge of high-voltage safety standards and handling procedures.

Communication: Clear communication in English.

Nationality: Due to the nature of our maritime defense and infrastructure projects, Dutch or NATO-country nationality is required.
