We are seeking an experienced Electronics Design Engineer with specialist expertise in High Voltage (HV) design to support the development of subsea power transmission equipment used in critical global infrastructure.
This role has a strong focus on IEC (phone number removed) compliance, including HV creepage, clearance, and insulation coordination for systems operating up to 21kV DC.
Working within a multidisciplinary engineering team, you will support the design, validation, and optimisation of advanced HV power converters and subsystems across the full hardware lifecycle.
Key Responsibilities
Design and develop high-voltage electronic subsystems for subsea power transmission equipment
Apply IEC (phone number removed) principles covering creepage, clearance, and insulation coordination
Resolve HV clearance challenges at system and switching level
Support the full hardware lifecycle from concept through to qualification
Conduct HV risk analysis and DFMEA activities
Define HV test strategies including insulation resistance, dielectric withstand, and partial discharge testing
Produce schematics, specifications, test plans, and technical reports
Required Experience
Degree in Electrical or Electronic Engineering
Mid to senior-level electronics hardware design experience
Strong expertise in HV electronics and power electronics
Proven experience applying IEC (phone number removed) within HV design environments
Strong understanding of HV creepage, clearance, insulation coordination, and electrical safety
Experience with DC-DC converters, HVDC systems, or power converters (~5kW)
Experience within regulated engineering environments (e.g. ISO9001)
Desirable Skills
Experience with HV switches and precision measurement circuits
Understanding of thermal management for high-power electronics
Experience using Altium Designer
Familiarity with Windchill or similar PLM systems
The Opportunity
This is an opportunity to work on high-reliability power electronics used in subsea infrastructure, supporting systems designed to operate continuously for decades in demanding environments
