The Opportunity

Electrical Design Engineer (Contract)

Location: California
Contract: 12 Months, with potential to extend | Full-Time
Working Arrangement: Onsite
Travel: Occasional / Regular

We are partnering with an innovative advanced aerospace and electric aviation company seeking an experienced Electrical Design Engineer to join its Energy Storage & Power Systems team.

This is an opportunity to work on next-generation electric aircraft, taking ownership of the electrical design and integration of high-voltage battery systems and power distribution architectures.

You will work across the full engineering lifecycle: from early architecture and trade studies through detailed design, analysis, testing and flight-ready hardware.

The role would suit an engineer with a strong background in high-voltage power systems, battery technology or electric propulsion who enjoys solving complex, hands-on engineering challenges in a fast-moving R&D environment.

What You'll Be Doing

You will act as a key technical contributor for high-voltage electrical systems, with responsibilities including:

• Architecting 400V+ high-voltage power distribution systems, including busbars, wiring harnesses, contactors, fuses and power electronics interfaces.
• Leading the electrical design of lithium-ion battery modules and packs, including voltage and temperature sensing, cell balancing and high-current interconnects.
• Supporting the development of high-power charging systems, including on-board and off-board charging architectures.
• Performing electrical analysis including power budgets, voltage drop, fault-current modelling and transient/steady-state simulation.
• Developing grounding, shielding and EMI/EMC strategies for safety-critical aerospace systems.
• Designing HV protection systems including HVIL, isolation monitoring and circuit protection.
• Supporting component selection across MOSFETs, IGBTs, contactors and high-power PCB designs.
• Leading electrical verification activities including high-current characterization, insulation-resistance testing and HiPot testing.
• Conducting FMEA and failure analysis to identify and mitigate electrical safety risks.
• Working closely with mechanical, software, systems and manufacturing engineering teams.
• Producing technical specifications, engineering reports and design documentation to support development and certification.

What We're Looking For

You'll ideally bring:

• B.S., M.S. or Ph.D. in Electrical Engineering or a related discipline.
• 8+ years of professional electrical design experience.
• Strong experience with high-voltage systems above 400V, ideally within aerospace, EVs, electric propulsion, automotive or heavy transportation.
• Deep understanding of high-power distribution, busbar design, creepage/clearance and electrical protection.
• Experience designing or integrating Battery Management System (BMS) hardware.
• Knowledge of lithium-ion battery systems, including voltage/current sensing, isolation, SoC and cell-balancing architectures.
• Proficiency with LTspice, PSpice, MATLAB/Simulink or similar electrical analysis tools.
• Experience with ECAD platforms such as Altium, Mentor Graphics or Zuken.
• Familiarity with NX and/or SolidWorks for electrical/mechanical integration.
• Strong knowledge of EMI/EMC, grounding and shielding.
• Ability to communicate complex electrical designs clearly across multidisciplinary engineering teams.

Desirable Experience

Experience in any of the following would be particularly valuable:

eVTOL or electric aircraft * aerospace battery systems * EV propulsion * high-power charging * CCS/MCS/NACS * DO-160G * DO-311A * ARP4754 * ARP4761 * aerospace certification * high-power PCB design

Previous certification experience is beneficial but not essential.

Why Consider This Opportunity

This is a chance to work at the intersection of aerospace, electrification and high-voltage battery technology, contributing directly to the development of a new generation of electric aircraft.

You'll be joining a highly technical engineering environment where your work will have a direct impact on aircraft power architecture, battery safety, performance and flight readiness.
