Power Electronics Engineer — Motor & Hybrid Systems

Build the electronics behind purposeful motion. Your power-conversion hardware will help ASKA connect electrical energy to propulsion performance, with design decisions that carry through from the bench to the vehicle.

Support ASKA's motor and hybrid-power leads with power-electronics hardware, electrical interfaces and propulsion integration. This shared foundation-team role connects motor drives, generator power conversion and the vehicle high-voltage system.

Employment Full-time proposed

Location & work arrangement Eagle Field · Palo Alto area / remote for analysis and design to be defined; hands-on integration and test visits to be discussed; availability for occasional testing at Eagle Field Airport required, with advance coordination

Shared power-electronics engineering support for the motor and hybrid-power leads.

Key working interfaces

Works with the Chief Electric Motor Engineer and Lead Hybrid-Electric Power Systems Engineer, coordinating battery and aircraft electrical interfaces.

What you’ll do

• Provide shared power-electronics and electrical-interface support to the motor and hybrid-power leads.
• Design gate-drive, sensing, protection, auxiliary-power and interface circuits against allocated requirements.
• Evaluate component derating, tolerances, losses and credible fault behavior before design release.
• Review PCB layout for current paths, switching loops, isolation, noise and manufacturability.
• Bring up prototypes using staged test procedures and appropriate high-voltage laboratory practices.
• Characterize transients, timing, thermal behavior and susceptibility, then resolve findings with the wider team.
• Maintain schematics, bills of material, analysis reports and changes tied to tested revisions.
• Develop and continually improve power-electronics test methods, measurement checks and acceptance criteria for assigned hardware; use prototype findings to strengthen repeatability, verification coverage and evidence tied to each revision.

Required qualifications

• Bachelor’s degree in electrical or electronics engineering, or equivalent practical expertise demonstrated through relevant work.
• 4+ years in power-converter circuit design and laboratory validation.
• Experience designing power-electronics schematics and PCBs, including gate drives, sensing, protection and isolated auxiliary supplies.
• Ability to evaluate component derating, switching-loop parasitics, creepage, clearance and mixed-signal noise during design reviews.
• Experience with oscilloscope-based bring-up, transient characterization and failure investigation on high-voltage converter hardware.
• Ability to explain technical decisions, keep accurate records and work effectively with the teams responsible for adjacent systems.

Preferred qualifications

Experience with SiC devices, mixed-signal layout and power-electronics failure analysis. Familiarity with design assurance and qualification testing is useful.

AI tools and automation: Preferred: experience using ChatGPT, Claude, Gemini, Microsoft 365 Copilot or equivalent tools for technical research, analysis, documentation or reporting. Where relevant, describe use of Claude Code, OpenAI Codex, Cursor, GitHub Copilot or equivalent tools for Python/MATLAB scripts, CAD/CAE workflow automation or test-data processing. Provide a specific example, your contribution, any measured time saved or quality improvement, and how you verified the result. Equivalent tools are welcome.

We welcome transferable experience from related industries. You do not need to meet every preferred qualification. Tell us what you have delivered and how your skills apply to this role.

Location & working arrangements

Eagle Field Airport · 11100 W Eagle Ave, Firebaugh, CA 93622

Eagle Field Airport is our primary development and manufacturing location. Palo Alto area or remote arrangements may be considered for engineering work that does not require hands-on access. All current openings require availability to participate in development and flight-testing activities at Eagle Field Airport from time to time, with advance coordination. Flight-test roles require on-site availability for preparation and campaigns. Scheduling and travel arrangements will be discussed for each role.

About ASKA

At ASKA, we are on a mission to build the world’s first AI sensor fusion and digital twin system that manages autonomous driving and autonomous flying in one vehicle. We are bringing ground and air autonomy together to support the warfighter—moving critical supplies, reaching people in need, and reducing exposure in dangerous environments. Our team works across aircraft engineering, intelligent software, electric propulsion, and advanced manufacturing, with development and testing at Eagle Field Airport in California. Bring your expertise. Take ownership. Help build technology that matters.

ASKA welcomes applicants with diverse backgrounds and relevant experience.
