Job Description

Senior Power Electronics Engineer

Location: Oxford, UK
Discipline: High-Power DC/DC Converter Design | Experimental Systems

The Role

We are seeking a Senior Power Electronics Engineer to lead the design, development, and validation of high-power DC/DC converters used in experimental and research-driven applications. This role is well-suited to an engineer who enjoys working on novel architectures, rapidly evolving requirements, and translating theoretical concepts into robust, testable hardware.

You will take technical ownership of power converter development from concept through to prototype testing, working closely with multidisciplinary teams across electronics, systems, and research functions.

Key Responsibilities

• Design and develop high-power DC/DC converters (from hundreds of watts to multi-kW) for experimental and prototype systems
• Define power architectures, topologies, and control strategies suitable for non-standard or research-led applications
• Lead schematic design, component selection, and power stage optimisation (SiC / GaN / silicon as appropriate)
• Design and review magnetics (transformers, inductors) for high-power, high-efficiency operation
• Oversee PCB layout reviews with a strong focus on EMI, thermal performance, and high-voltage safety
• Build, test, and debug prototypes; lead lab-based validation and experimental testing
• Collaborate with systems, mechanical, and research teams to integrate power electronics into wider platforms
• Support documentation, design reviews, and knowledge transfer within the engineering team

Required Skills & Experience

• Degree (BSc, MSc, or PhD) in Electrical / Electronic Engineering or related field
• Strong commercial or research experience in power electronics design
• Proven experience designing high-power DC/DC converters
• Deep understanding of:

• • Power converter topologies
  • Switching devices (MOSFETs, IGBTs, SiC, GaN)
  • Magnetics design and power passive selection
  • Control techniques and feedback loops

• Hands-on experience with lab testing, debugging, and experimental validation
• Familiarity with simulation tools (SPICE, PLECS, MATLAB/Simulink)
• Experience with PCB design tools (Altium, OrCAD, or similar)

Desirable Experience

• Exposure to high-voltage or high-current systems
• EMI/EMC mitigation in experimental or non-standard systems
• Leadership or mentoring of junior engineers
• Rapid prototyping and iterative design cycles

What’s on Offer

• Opportunity to work on cutting-edge experimental power electronics
• High technical autonomy and influence over design decisions
• Access to advanced lab facilities and test equipment
• Competitive salary and benefits package
• Collaborative engineering culture based in Oxford
