Electronics Design Engineer - High Voltage; HV Design

Position: Electronics Design Engineer - High Voltage (HV Design)
Location: Greenwich

Electronics Design Engineer - High Voltage (HV Design) - RATE DOE - London - 12-Month Contract

We are seeking an experienced Electronics Design Engineer specialising in High Voltage (HV) design to support the development of subsea power transmission equipment used in critical global infrastructure.

This role focuses on the design, validation and optimisation of high-voltage electronics capable of generating up to 21kV DC, ensuring long-life reliability and compliance with international safety standards.

Working within a multidisciplinary engineering team, you will contribute to the development of advanced HV power converters and subsystems, supporting the full hardware lifecycle from concept through to qualification.

Key Responsibilities

Design and develop high-voltage electronic subsystems for subsea power transmission equipment
Assess and resolve HV creepage and clearance requirements in line with IEC (phone number removed)
Develop solutions for HV clearance challenges at system and switching levels
Contribute across the full hardware design lifecycle from concept to qualification
Conduct HV risk analysis and DFMEA for high-voltage systems
Define HV testing strategies, including insulation resistance, withstand testing and partial discharge validation
Produce engineering documentation including schematics, specifications, test plans and reports

Required Experience

Degree in Electrical or Electronic Engineering
Mid to senior Engineering experience in electronics hardware development
Strong expertise in high-voltage electronics and power electronics
Experience designing DC-DC converters, HVDC systems, or power converters (~5kW)
Strong understanding of HV design principles including creepage, clearance and insulation coordination
Experience working within regulated engineering environments (e.g. ISO
9001)

Desirable Skills

Specialist knowledge of IEC (phone number removed) HV safety standards

Experience with HV switches and precision measurement circuits
Understanding of thermal management for high-power electronics
Experience using Altium Designer
Familiarity with PLM systems such as Windchill

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
