Job summary

KO2 Embedded Recruitment Solutions Ltd is seeking a Power Electronics Engineer to develop high-power conversion systems (10 kW+), focusing on wide-bandgap SiC/GaN devices and solid-state transformer architectures, in Newcastle upon Tyne. The role covers design, simulation, prototyping, testing and certification support.

You will work with MV/HV SiC and GaN devices, contribute to SST architectures, and help shape the company’s power hardware as it scales.

Qualifications

• Hands-on design experience with medium- or high-voltage SiC power devices.
• Practical experience designing with GaN devices.
• Experience of solid-state transformers, or SST design experience or related high-frequency isolated conversion work.
• Strong background in power electronics design, control methods and system simulation.
• Experience of analogue and digital circuit development.
• Solid understanding of switching devices, gate drive, thermal design and magnetics.
• Knowledge of embedded control and EMC behaviour in high-power systems.
• Ideal: high-power product development in energy/grid/industrial/data-centre domains.

Responsibilities

• Design high-power converters using MV/HV SiC and GaN devices.
• Develop SST architectures or lead SST design efforts.
• Model and simulate converter designs in PLECS; use CAD tools like CADSTAR.
• Carry out functional, thermal and electrical testing of prototypes.
• Run EMC and power compliance testing; implement fixes as needed.
• Write technical documentation and safety files to support approvals.

Job description

Power Electronics Engineer - SiC, GaN and Solid-State Transformers

Location: Newcastle upon Tyne
Salary: Up to £62,000 + relocation paid

KO2's client is a fast-growing technology company developing high-voltage server systems for quantum analytics. They're expanding their hardware team and are looking for a Power Electronics Engineer with wide-bandgap experience to help design their next generation of high-power conversion systems.

You'll design and develop high-power conversion systems rated at 10 kW and above, covering AC-AC, DC-DC and DC-AC platforms. Your work will span simulation and modelling, prototyping, testing and validation, through to supporting certification.

The role focuses on wide-bandgap technology. You'll work with medium- and high-voltage silicon carbide (SiC) and gallium nitride (GaN) devices, and you'll help develop solid-state transformer (SST) architectures. You'll have a central part in shaping the company's power hardware as it grows.

Key responsibilities

• Design high-power converters using MV/HV SiC and GaN switching devices
• Develop solid-state transformer (SST) architectures, or take a leading part in them
• Model and simulate converter designs in PLECS or similar, and use PCB CAD tools such as CADSTAR
• Carry out functional, thermal and electrical testing of prototypes
• Run EMC and power compliance testing, and design in fixes for any issues found
• Write technical documentation and safety files to support approvals and certification

Essential skills and experience

• Hands-on design experience with medium- or high-voltage SiC power devices
• Practical experience designing with GaN devices
• Experience of solid-state transformers, or the ability to take on SST design. This could come from related high-frequency isolated conversion work such as DAB or resonant converters
• A strong background in power electronics design, control methods and system simulation
• Experience of analogue and digital circuit development
• A good understanding of switching devices, gate drive, thermal design and magnetics
• An understanding of embedded control and EMC behaviour in high-power systems

Desirable experience

• High‑power product development in energy, grid, industrial or data‑centre applications
• Experience of high-frequency transformer and magnetics design for isolated converters
• Knowledge of insulation coordination and safety standards for MV/HV equipment

What's on offer

• A salary of up to £62,500
• Full visa sponsorship for the right candidate
• The chance to work on advanced wide-bandgap and SST technology
• A key role in a fast-growing company, with real influence over its hardware
