Now, we’re building our next-generation aircraft, XBAT, like no other—one that will push the boundaries of innovation and performance. We are looking for an entry-level Power Electronics Engineer who is excited to help bring X-BAT’s next-generation power systems to first flight. In this role, you will own a meaningful project directly tied to our power architecture critical path, while receiving direct mentorship from senior power and electrical engineers. We value first-principles thinking, hands-on engineering, and extreme ownership. #LI-JM2 #LA Full-time regular employee offer package: Pay within range listed + Bonus + Benefits + Equity Temporary employee offer package: Pay within range listed above + temporary benefits package (applicable after 60 days of employment) Salary compensation is influenced by a wide array of factors including but not limited to skill set, level of experience, licenses and certifications, and specific work location. All offers are contingent on a cleared background and possible reference check. Military fellows and part-time employees are not eligible for benefits. Please speak to...

Responsibilities:
• Own a power electronics design that directly impacts X-BAT system performance and major flight test milestones, supported by a senior engineer who provides technical guidance and review.
• Contribute to the full hardware lifecycle including concept development, modeling, worst-case analysis, schematic capture, simulation, prototyping, bring-up, verification, integration, and flight test support.
• Design and analyze low-voltage and high-voltage power systems including DC-DC converters, inverters, motor controllers, battery systems, power distribution, and protection circuits.
• Design systems across power ranges from <1 kW low-power loads to >10 kW high-power applications while balancing efficiency, thermal constraints, EMI/EMC performance, and reliability.
• Partner with ECAD engineers on PCB layout for power density, thermal performance, EMI mitigation, and manufacturability.
• Execute hands-on board bring-up, debug, root-cause analysis, and validation using oscilloscopes, power supplies, electronic loads, and other test equipment.
• Support environmental, stress, and qualification testing (HALT, vibration, temperature cycling) for aerospace-grade reliability.
• Collaborate closely with Mechanical, Embedded, Software, Production, and Aircraft teams to ensure robust system integration and clear interface ownership.
• Drive disciplined engineering practices including documentation, risk reduction, and closing the loop between analysis and test results.
Requirements:
• B.S. in Electrical Engineering or equivalent.
• Strong technical fundamentals in circuits, electronics, and power systems.
• Hands-on experience (coursework, labs, clubs, or internships) with power electronics such as converters, motor drivers, batteries, or high-power systems.
• Familiarity with electrical design tools (Altium, KiCad, etc.).
• Experience using lab equipment such as oscilloscopes, power supplies, e-loads, and multimeters.
• Participation in an engineering team/club or hands-on project experience.
• Ability to obtain a S//SAR level security clearance desired.
