Electronics Design Engineer - High Voltage (HV Design)

Electronics Design Engineer - High Voltage (HV Design) - Umbrella / PAYE Rate DOE - London - 12-Month Contract

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.
