The Principal Engineer – Power Electronics will lead the development of advanced power electronics systems from clean-sheet concept through to validated hardware. The role is responsible for defining requirements, leading circuit and magnetic design, and overseeing prototype implementation for traction inverters, DC/DC converters, On-Board Chargers (OBC), and associated electrified powertrain systems.

This is a senior technical leadership role requiring deep expertise in power electronics, strong commercial awareness, and the ability to lead multidisciplinary teams in delivering innovative, high-performance, and safety-compliant solutions.

Key ResponsibilitiesTechnical Leadership

• Lead the specification, design, and validation of power electronics systems including traction inverters, DC/DC converters, AC/DC systems, and OBCs

• Own magnetics and capacitor design for high-performance power converters

• Lead design of digital and mixed-signal control systems and processing platforms

• Oversee simulation activities using industry-standard tools (e.g., Simscape, PLECS)

• Guide control strategy development including motor control and converter control schemes

• Ensure compliance with relevant standards (IEC61508, ISO26262, CISPR25, EMC directives)

• Lead hardware development from concept through prototype and test

System & Validation

• Develop and validate designs in virtual, HiL, and hardware environments

• Oversee EMC mitigation strategies and noise attenuation

• Support PCB layout, mechanical integration, and thermal management strategies

• Contribute to thermal and fluid system simulation where required

Project & Commercial Leadership

• Lead multi-person, cross-functional engineering projects

• Build and manage strong technical relationships with customers

• Take ownership of proposals, business development activities, and technical presentations

• Support marketing activities and represent the company externally

• Operate effectively within technically and commercially challenging environments

Capability & Team Development

• Mentor and support the professional development of engineers within the function
