Senior Power Electronics Engineer

Contract Opportunity: Power Electronics Engineer (OUTSIDE IR35 – QDOS Assessed) Location: Hybrid Working - Berkshire and from home Duration: 12 Months (with likely extension) Rate: High Pay rate Start Date: ASAP IR35 Status: Outside IR35 (QDOS assessed) Condensed working week available Overview: An experienced Power Electronics Engineer is required for a contract position (Outside IR35) to support the design, development, and qualification of high-reliability AC-DC and DC-DC power conversion systems . Could you be interested or know anyone interested in the below opportunity? The role is for Power Electronics development to design, develop, and qualify AC-DC and DC-DC power conversion systems for satellite communications applicationl. This role requires strong expertise in power conversion, EMI/EMC compliance, and MIL-STD standards. Key Responsibilities: Design & Development Design AC-DC front-end converters (85-265 VAC to regulated DC rails). Develop isolated and non-isolated DC-DC converters to support RF, digital, and control subsystems. Optimise designs for efficiency, thermal performance, reliability, and compact form factor. EMC / EMI Compliance Ensure designs comply with MIL-STD-461G and relevant EMC/EMI standards. Implement filtering, shielding, grounding, and PCB layout techniques to control emissions and susceptibility. Testing & Validation Develop and execute test procedures for power performance and EMC compliance. Conduct lab testing with oscilloscopes, spectrum analysers, LISNs, and other EMC equipment. Support qualification testing for rugged environments (temperature, humidity, vibration, shock). Integration & Collaboration Work with RF, digital, and mechanical engineers to integrate power systems into terminal architectures. Support design reviews, FMEA/FTA, and reliability analysis. Documentation & Compliance Produce schematics, design reports, test documentation, and compliance evidence for certification and customer reviews Requirements Bachelor's or Master's degree in Electrical/Electronic Engineering 10 years' experience in hardware design, integration, testing, and troubleshooting. Proven experience in AC-DC and DC-DC power supply design (up to kW range desirable). Strong understanding of EMC/EMI principles and MIL-STD-461G compliance. Hands-on experience with PCB design for power and EMC. Skilled in simulation tools (PSPICE, LTspice, MATLAB/Simulink, etc.) Proficient in lab validation and EMC test equipment (spectrum analysers, LISNs, conducted/radiated test setups). Desired Skills: Experience with power factor correction (PFC) topologies. Familiarity with ruggedised electronics for defense/field deployments. Knowledge of thermal management and environmental protection. Experience with compliance testing and working with certification bodies. Exposure to automated test setups for power and EMC. The client are happy with a hybrid working arrangement, approximately 3 days onsite and two from home although this can be flexible for the right person. Application Process: If you are a seasoned Power Electronics Engineer looking for your next OUTSIDE IR35 contract , please apply with an up-to-date CV highlighting relevant experience. Immediate availability or short notice is preferred.
