The Opportunity

We are seeking a highly experienced Principal Power Electronics Engineer to lead the development of advanced power conversion systems for cutting-edge electrification applications.

This is a hands-on technical leadership role where you will take ownership of architecture definition, design, and verification of power electronics solutions, including motor drives and control systems. You will work closely with a multi-disciplinary engineering team and external suppliers to deliver high-performance, robust products for demanding applications such as electric vehicles and energy systems.

Key Responsibilities

Design & Development

• Lead the design and development of innovative power electronic systems, including converters, inverters, and motor drives
• Define system architectures, selecting optimal topologies to balance efficiency, cost, size, and performance
• Produce detailed electronic designs, including schematics and oversight of PCB layouts
• Design and specify key components including switching devices, gate drives, magnetics, and filtering systems
• Perform simulation and analysis to validate system performance and design decisions

Control & Performance

• Define control strategies and system requirements for monitoring and operation
• Analyse power losses and support thermal management strategies
• Ensure designs meet performance, safety, and regulatory requirements

Testing & Validation

• Lead commissioning and verification of systems, ensuring compliance with specifications and standards
• Conduct root cause analysis and resolve technical issues
• Support prototype builds, system integration, and testing activities
• Work safely with high-voltage and high-power systems

Engineering Governance

• Deliver engineering activities in line with project timelines, quality standards, and change control processes
• Support requirements management, FMEA, and functional safety activities at hardware level
• Produce and maintain high-quality technical documentation

Collaboration & Stakeholder Management

• Work closely with cross-functional teams including software, mechanical, and systems engineering
• Engage with suppliers and manufacturers to support component selection and product delivery
• Build and maintain strong relationships with external technology partners
