- Strong experience in HV substation primary plant design
- Background in transmission & distribution projects (up to 400kV desirable)
- Familiarity with utility standards (e.g. National Grid, SPEN, SSEN or equivalent)
- Experience delivering FEED and detailed design packages
- Strong understanding of HV electrical systems and substation design principles
- Experience working in multidisciplinary engineering environments
- Strong technical review and quality assurance capability
What’s on offer:
- Work on major UK transmission and substation infrastructure projects
- Full lifecycle engineering exposure (FEED → detailed design → commissioning support)
- Senior technical role with genuine design ownership
- Hybrid working with flexibility across UK office locations
- Collaborative multidisciplinary engineering environment
