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.
