Overview
The Senior Power Electronics Engineer will engage in the design, development, and qualification of high-reliability AC-DC and DC-DC power conversion systems, primarily for satellite communications applications. This hybrid role allows collaboration with other engineering disciplines and requires a strong background in power conversion and compliance with MIL-STD standards. The position is assessed as outside IR35 and offers a condensed working week.
Responsibilities
- Design AC-DC front-end converters to convert line voltage to regulated DC rails.
- Develop isolated and non-isolated DC-DC converters for RF, digital, and control subsystems.
- Optimize designs focusing on efficiency, thermal performance, reliability, and compactness.
- Ensure compliance with MIL-STD-461G and EMC/EMI standards through design techniques.
- Develop and execute test procedures for power performance and EMC compliance.
- Conduct lab testing using oscilloscopes and spectrum analyzers.
- Collaborate with RF, digital, and mechanical engineers for integration into system architectures.
- Produce documentation including schematics, design reports, and compliance evidence for certification.
Requirements
- Bachelor's or Master's degree in Electrical/Electronic Engineering.
- 10+ years of experience in hardware design, integration, testing, and troubleshooting.
- Proven design experience with AC-DC and DC-DC power supplies (up to kW range preferred).
- Strong understanding of EMC/EMI principles and MIL-STD-461G compliance.
- Hands-on experience with PCB design for power and EMC applications.
- Proficiency in simulation tools such as PSPICE, LTspice, or MATLAB/Simulink.
- Experience with lab validation and EMC test equipment, including spectrum analyzers and LISNs.
- Familiarity with power factor correction (PFC) topologies and ruggedized electronics for defense applications is a plus.
