About the role

Entry-level Power Electronics Engineer to contribute to X-BAT’s next-generation power systems, owning a meaningful project tied to the power architecture critical path with mentorship from senior engineers.

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.

Qualifications

  • 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.
