We are supporting a highly specialised engineering organisation developing high-reliability power systems for critical long-life infrastructure applications.

This is a senior System Design role focused on high-voltage DC-DC power architecture. The product is a modular multi-stage power conversion system, converting low-voltage DC input into multi-kilovolt DC output, designed to operate with 99.999% availability over a 25-year lifecycle.

This is not a pure board-level design role and not a requirements-capture position. You will own the system architecture, translating product requirements into subsystem specifications and defining the overall technical strategy.

Key Responsibilities

• Define and develop DC-DC system architecture
• Translate product feature lists into subsystem requirements
• Allocate reliability targets across converters and subsystems
• Define redundancy strategy and technical development roadmap
• Work closely with electronics, software and mechanical teams
• Support technical reviews, validation and long-term product evolution

Essential Experience

• 8+ years in power electronics
• Hands-on design experience with DC-DC power supplies (3-5kW+)
• Strong understanding of control loops and power converter behaviour
• Experience designing high-reliability systems
• Experience taking complex products from concept to production
• Strong written and verbal technical communication

Desirable Backgrounds

• Industrial power supplies
• Rail or heavy industry
• High-voltage systems
• Energy or grid-related power conversion

Automotive validation-only profiles are unlikely to be suitable unless they have genuine DC-DC architecture ownership.

This is a succession opportunity, working alongside an established Principal Engineer with long-term product ownership.

Excellent benefits package on top of a market leading salary, including car allowance, 10% bonus, private medical & health insurance, life assurance (8x salary), and more
