I'm supporting a long-established UK engineering company specialising in power systems and grid infrastructure to recruit a Lead Design Engineer with strong expertise in high-voltage (HV) substation design . This is a senior, hands-on technical role where you'll lead the design and delivery of complex transmission and distribution (T&D) projects. You'll play a critical role in shaping engineering solutions across AIS and GIS substations , ensuring designs are robust, compliant, and fit for purpose from concept through to commissioning. Key Responsibilities: Lead the end-to-end design of HV substations (typically 11kV-400kV) across transmission and distribution networks

Deliver detailed design for both AIS (Air Insulated Substations) and GIS (Gas Insulated Substations)

Perform and review busbar design and calculations , including thermal rating, fault level withstand, and mechanical forces

Produce and approve key design deliverables: Single Line Diagrams (SLDs)

Protection & Control schematics

General Arrangements (GA) and layout drawings

Cable schedules and interconnection diagrams

Undertake primary and secondary design coordination
