  • 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
  • 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
