Our team solves tough, meaningful problems that create a safer, more secure world.

We are seeking a highly motivated Power Electronics Engineer to join our multidisciplinary engineering team supporting advanced aerospace and defense programs. The engineer will contribute to the design, development, analysis, test, and integration of power conversion hardware across a wide variety of applications including airborne, space, radar, and next‑generation power platforms. This P2-level role is ideal for engineers with early-career experience who are ready to take technical ownership of subassemblies and work closely with senior engineers to deliver high-performance, high-reliability power solutions.

What You Will o

• Design and develop power conversion circuits including AC/DC, DC/DC, servo/motor controls, filters and power system architectures.
• Create schematics, perform component selection, and support PCB layout for power boards.
• Perform detailed analysis including SPICE simulation, worst-case analysis, derating, reliability assessments, and thermal modeling.
• Develop magnetics designs (inductors, transformers) including performance modeling and winding specifications.
• Apply emerging technologies including SiC and GaN devices to achieve high power density and high efficiency.
• Support EMI/EMC compliance through simulation, design techniques, and testing aligned with MIL‑STD and aerospace standards.
• Execute hands‑on lab testing including bring‑up, debugging, characterization, and validation of power hardware.
• Develop test plans, procedures, and documentation to support verification across development stages.
• Collaborate with systems, digital design, mechanical/thermal engineering, manufacturing, and integration teams.
• Contribute to requirements development, traceability, and design documentation.
• Support root‑cause analysis and production issue resolution.
• Participate in design reviews, trade studies, and IRAD / technology maturation tasks.

Qualification You Must Have
