U.S. Citizenship or Eligibility Required

Are you a Power Electronics Engineer who enjoys turning complex designs into working hardware? Have you developed power converters, switching power supplies or high-power electrical systems? Would you like greater ownership of advanced power electronics from design through prototype and testing? If so, this opportunity may be the right next step for you.

This rapidly growing aerospace and defence organisation develops advanced electrical hardware for demanding applications. Engineers work in small technical teams with the freedom to innovate, challenge existing designs and develop new technologies.

The Senior Power Electronics Engineer will develop 10–100kW power converters, PFC circuits and DC-DC power supplies, taking ownership from initial design through hardware validation.

As the Senior Power Electronics Engineer your responsibilities will include

• Designing high-power converters, switching power supplies and power conversion circuits
• Developing PFC, DC-DC converter topologies and control strategies
• Designing transformers, inductors, magnetics and EMI filtering components
• Developing schematics, PCB layouts and prototypes, supporting hardware bring-up and debugging
• Testing, troubleshooting and optimising power electronics for demanding aerospace applications

As the Senior Power Electronics Engineer you will bring

• Hands‑on experience developing power electronics, converters or switching power supplies
