Job summary

RTX in El Segundo, CA is seeking an experienced Power Electronics Engineer to lead the design of AC/DC and DC/DC converters, motor drives, and high‑density power boards. You will own circuit‑level designs, guide PCB layout, and perform advanced simulations for reliability and thermal performance.

The role requires hands‑on prototype bring‑up, EMI/EMC compliance, and collaboration across systems, mechanical/thermal, and manufacturing teams.

Qualifications

• Bachelor’s degree in Electrical Engineering or related field.
• 5+ years in power electronics design, analysis, or test.
• Experience with switched‑mode converter topologies (buck, boost, flyback, half/full bridge, resonant, PFC, motor control).
• Proficient with SPICE, LTspice, PLECS, MATLAB/Simulink for design and verification.
• Lab experience with oscilloscopes, power analyzers, high‑voltage equipment, and/or electronic loads.
• Experience with high‑power, high‑voltage safety principles and best practices.

Responsibilities

• Lead design and development of power electronics hardware including converters, motor drives, and complete power system architectures.
• Own circuit-level and subsystem designs, performing schematic creation and guiding PCB layout for high‑density/high‑reliability boards.
• Perform advanced engineering analysis including SPICE/PLECS simulation, worst‑case analysis, derating, reliability modeling, and thermal/electromagnetic evaluations.
• Develop and validate magnetics designs with electrical models, core/winding selections, and optimization for size/efficiency/thermal performance.
• Drive adoption of SiC and GaN devices; develop gate-driver strategies and high‑frequency architectures.
• Ensure EMI/EMC compliance through modeling, design techniques, and testing aligned with MIL/ DO standards.
• Lead hands‑on activities including prototype bring‑up, debugging, characterization, and formal validation.
• Develop test plans, procedures, and verification documentation across development stages.
• Collaborate cross‑functionally to ensure cohesive subsystem performance.
• Contribute to requirements, traceability, and engineering documentation.
• Drive root‑cause analysis, corrective actions, and production support.
• Participate in design reviews, trade studies, and technology maturation activities.
• Mentor P1–P2 engineers with technical guidance.
