• Translate system and customer requirements into suitable converter architectures and circuit topologies, balancing efficiency, power density, thermal performance, reliability, cost and delivery risk.
• Design, model and simulate power conversion circuits, and use analysis and test evidence to support technical decisions.
• Select appropriate semiconductor devices, passive components and supporting technologies, demonstrating the application‑level benefits and limitations of different solutions.
• Develop or technically review schematics, PCB layouts and associated design documentation, with particular attention to electrical, electromagnetic, thermal and safety requirements.
• Plan and undertake prototype build, commissioning, verification testing, fault investigation and design improvement.
• Provide technical coordination and guidance to engineers and technicians contributing to assigned projects.
• Manage technical risks, maintain appropriate engineering records and contribute to project planning and progress reviews.
• Communicate technical progress, results and recommendations clearly to customers, project teams and wider audiences.
• Collaborate with Advanced Packaging, RF/Microwave, Photonics and other engineering teams to deliver multidisciplinary projects and engineering demonstrators.
• The Candidate
• A PHD, degree or postgraduate qualification in power electronics, electrical/electronic engineering or a related discipline, or equivalent relevant suitable industrial experience.
• Substantial industrial experience in power electronics, with evidence of successfully delivering converter, inverter, power‑supply or motor‑drive projects or work packages.
• Hands‑on experience of designing, building, commissioning and testing power electronic converters or related systems.
• Strong understanding of power‑converter topologies and the ability to evaluate their operating principles, benefits, limitations and suitability for different applications.
• Sound theoretical knowledge combined with the ability to apply engineering judgement to practical design and troubleshooting.
• Experience with circuit modelling and simulation tools and the interpretation of simulation and test results.
• Experience of schematic development and PCB design or technical review for power electronic systems.
• Understanding of switching behaviour, gate‑drive requirements, parasitic effects, electromagnetic compatibility and thermal management.
• Experience of working in multidisciplinary projects and managing interfaces with PCB, packaging, mechanical, thermal and embedded‑control activities.
• Strong analytical and problem‑solving capability, including the ability to investigate complex technical issues and develop practical solutions.
• Able to plan and take ownership of technical work packages, risks, documentation and delivery.
• Able to communicate complex technical subjects clearly to engineering, customer and non‑specialist audiences.
• Able to provide technical guidance and constructive support to engineers and technicians.
• Collaborative and comfortable working across teams, with customers and with external partners.
• Postgraduate research experience or a Ph D in power electronics or a relevant discipline.
• Solid‑state transformer, medium‑voltage converter or high‑power conversion experience.
• Practical experience of wide‑bandgap semiconductor technologies, including Si C or Ga N devices.
• Systems‑engineering approaches to requirements, interfaces, verification and technical risk.
• Embedded control and digital implementation of power‑converter control.
• Engineering lifecycle, configuration management or design‑review processes.
• Translation of research outputs or early concepts into functional prototypes.
• EDA, PCB design or embedded‑programming experience.
• Structured problem‑solving methodologies, such as 8D.
