Principal Engineer-Power Electronics

In the role of Principal Engineer of Power Electronics, you will develop power electronics systems for a wide variety of applications from clean sheet through to hardware. This will involve developing requirements, circuit design, component selection and managing the implementation of prototype hardware for traction inverters, DCDC converters, On Board Chargers and other associated systems. Development of the functionality and performance of bespoke designs and new technology will be required in the virtual, HiL and hardware testing environments in our well equipped facility.

The role involves operating in a dynamic project environment including technical, commercial and customer management.

• Define and own the system-level architecture, design methodology, and technical authority for power electronics systems, including magnetics, capacitors, and active/passive components across converter and inverter platforms.
• Architect mixed-signal systems and embedded processing platforms, ensuring robust integration of sensing, control, diagnostics, and protection functions.
• Architect and review control strategies for power converters and inverters, ensuring alignment with hardware constraints, EMC requirements, functional safety objectives, and system-level performance
• Act as technical authority for functional safety and EMC compliance, guiding system architecture, design trade-offs, and verification activities in accordance with IEC 61508, ISO 26262, and CISPR
• Provide technical governance and senior engineering leadership across multi-disciplinary, cross-functional programs with significant technical and commercial complexity.
• Build, maintain, and own senior technical relationships with key customers, acting as a trusted technical advisor and escalation point.
• Identify, develop, and institutionalize new technical capabilities, design standards, and best practices aligned with long-term technology and business strategy.
• Shape and own the technical vision for major proposals and business development activities, including customer engagement, solution definition, technical risk assessment, and external representation of the company’s power electronics capability.
• Drive continuous professional development by mentoring engineers at all levels and fostering a collaborative, high-performance engineering culture.
• Act as a role model for the company’s values, professional standards, and engineering.

• Deep, hands-on experience delivering high-power power electronics systems (e.g., traction inverters, OBCs, DC/DC, AC/DC) and associated magnetics/actives/passives for demanding, safety-critical
• Demonstrated capability as a technical authority across different safety-critical sectors (e.g., automotive, aerospace, off-highway, commercial vehicle, defense, clean energy, marine), including customer-facing technical leadership.
• Proven experience in digital and mixed-signal control, sensing, and interface circuits, including embedded processing platforms and real-world implementation constraints.
• Strong track record in EMC-aware design and noise mitigation, including layout practices, filtering, grounding, shielding, common-mode management, and test correlation/troubleshooting.
• Expertise in multi-domain modeling and simulation of power electronic and magnetic systems (electrical, control, thermal, EMC), with demonstrated correlation between simulation and hardware
• Ability to plan, lead, and govern multi-person development projects, including technical risk management, structured design reviews, and cross-functional
• Experience with advanced motor drive control concepts (FOC, field-weakening, over modulation, harmonic injection for NVH, fault handling and protection) across multiple machine types (1PM, SPM, IM/ASM, SR).
• Demonstrated delivery of power electronics hardware from lab prototype through rig validation to production-intent or sector-qualification environments, including verification planning.
• Strong competence overseeing PCB layout and design-for-manufacture/assembly considerations, including isolation, creepage/clearance, thermal paths, and mechanical packaging constraints.
• Experience with thermal, fluid, and heat-transfer simulation and management for power electronics systems, including heatsinks, cold plates, and system-level thermal derating strategies.
• Formal training and a strong safety discipline for high-voltage/high-power laboratory work, test infrastructure, and safe operating procedures.

• Bachelor’s degree (BS) in Electrical Engineering, Power Electronics, or a closely related discipline with typically 12+ years of relevant experience, or
• Master’s degree (MS) with typically 8+ years of relevant experience, or
• Doctorate (PhD) with typically 5+ years of relevant industry

In all cases, candidates must demonstrate Principal-level technical authority, system ownership, and cross-program influence.
