Role Overview

Our Space & Defense Group develops high-reliability avionics, embedded computing, payload electronics, power distribution, and spacecraft systems for NASA, civil space, and defense missions.

We are seeking an exceptional Senior Power Electronics Design Engineer —a recognized technical leader with a proven record of designing power elements (DC/DC, Motor Control, power switches) for circuit cards for demanding aerospace applications. This role is ideal for a top-tier power design professional who combines deep technical expertise, speed and rigor in execution, and uncompromising attention to detail to deliver world-class, error-free designs that perform reliably in mission-critical environments.

What You'll Do

• Architect and design high-reliability power electronics including DC-DC converters and related subsystems such as inverters, motor drives, or battery-management systems.
• Perform circuit design, simulation, component selection, schematic capture, and guide PCB layout, thermal, and EMI/EMC considerations.
• Lead hardware bring-up, integration, debug, verification, and qualification activities.
• Develop and review specifications, design reviews, test plans, and verification documentation.
• Solve complex technical issues using structured root-cause analysis.
• Provide technical mentorship and design guidance to less experienced engineers.
• Collaborate with systems, software, mechanical, manufacturing, supply chain, and quality teams throughout the product lifecycle.
• Ensure designs meet aerospace and defense reliability, environmental, and performance requirements.

Required Qualifications

• Bachelor’s degree in electrical engineering or related discipline.
• 8+ years designing power electronics for aerospace, defense, industrial, or other high-reliability applications.
• Strong experience designing DC-DC power converters or closely related power conversion circuits.
• Experience with schematic capture and PCB design tools (Cadence Allegro, Altium, or similar).
• Experience using simulation tools such as SPICE, MATLAB/Simulink, Mathcad, or equivalent.
• Strong understanding of power semiconductor devices. MOSFET experience required; IGBT, SiC, and GaN experience is beneficial.
• Experience supporting hardware through the full product lifecycle from architecture through qualification and production.
• Strong communication, collaboration, and technical leadership skills.

Preferred Qualifications

• Master’s degree in electrical engineering, Power Electronics, or related field.
• Experience developing electronics for harsh-environment or space applications.
• Experience with radiation-tolerant or radiation-hardened electronics.
• Experience with motor control, reliability analysis (FMEA/MTBF), or system integration.

Experience mentoring engineers and leading technical design reviews
