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 62368-1
- 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. ISO9001)
Desirable Skills
- Specialist knowledge of IEC 62368-1 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.
