Electrical Engineer - Battery Cabinets

About the role

An experienced Electrical Engineer is sought to design, develop and validate battery cabinet systems for energy storage and backup power applications. The engineer owns the electrical architecture of the cabinet, from cell and module integration through BMS, protection, power distribution and thermal and safety interfaces, taking products from concept through certification and production.

Key responsibilities

• Design the electrical architecture of battery cabinets, including DC bus, busbars, fusing, contactors, disconnects and cabling
• Define and review schematics, wiring diagrams, harness drawings, BOMs and panel layouts
• Integrate and configure BMS hardware, including communication with inverters, PCS and site controllers (CAN, Modbus, RS-485)
• Perform electrical analysis: short-circuit, fault current, voltage drop, thermal derating and protection coordination
• Select and specify components such as DC breakers, fuses, relays, current sensors and power supplies
• Support thermal management and cooling system integration, including fans, HVAC and liquid cooling controls
• Plan and run prototype builds, bench testing and validation, including insulation resistance, hipot and functional and endurance tests
• Ensure compliance with applicable standards and support third-party certification (e.g. UL 9540/9540A, UL 1973, IEC 62619, IEC 62477, UN 38.3, NFPA 855)
• Collaborate with mechanical, firmware, safety, manufacturing and supply chain teams on DFM/DFA and cost optimization
• Troubleshoot field and production issues, perform root cause analysis and drive corrective actions
• Maintain design documentation, change control (ECN/ECO) and test reports

Required profile

• Bachelor's degree in Electrical Engineering, Power Electronics or a related field
• Minimum 5 years of hands-on experience in electrical design of battery cabinets, battery racks or battery energy storage systems (BESS)
• Strong understanding of lithium-ion battery systems (LFP, NMC) and DC power distribution
• Experience with BMS integration and battery protection architecture
• Working knowledge of relevant safety and certification standards

Required skills

• Electrical CAD tools such as EPLAN, AutoCAD Electrical, SolidWorks Electrical or Altium
• Test equipment such as multimeters, oscilloscopes, battery cyclers and thermal cameras
• Strong analytical, documentation and communication skills
