Overview
We’re looking for a hands-on Site Electrical Commissioning Engineer to support the delivery of electrical commissioning activities on a major UK site. This is a self-delivery commissioning environment — meaning you must be comfortable personally carrying out testing and commissioning of electrical assets with minimal supervision/support.
If you’ve got strong on-site commissioning experience across LV and MV systems, thrive in fast-paced construction/industrial environments, and can work with minimal supervision, this is a great opportunity to step into a key delivery role.
What you’ll be doing
- Lead and execute on-site electrical commissioning activities and reporting
- Carry out inspections, test/verification and functional performance testing
- Work closely with Project Managers, Engineers, HSE and other site stakeholders to plan and deliver commissioning safely and efficiently
- Review design documents/drawings for compliance with specs, standards and codes
- Identify, troubleshoot and resolve commissioning issues/defects; manage close-out
- Maintain and update commissioning documentation including punch lists
- Coordinate with site interfaces including Siemens, LOTO and admin functions
- Support safe systems of work, including HSE compliance and permit/LOTO processes
Essential experience (must-have)
- Proven site-based commissioning experience in electrical systems
- Hands-on commissioning/testing of electrical assets including:
- LV & MV switchgear
- Generator Circuit Breaker (GCB)
- CT & VT testing
- Transformer testing
- Ability to work independently and deliver commissioning without reliance on supervision/support
- Strong understanding of relevant standards, codes and safe working practices
- Clear documentation and communication skills (reports, test evidence, punch lists)
Desirable
- Familiarity with Siemens systems/interfaces
- Experience with structured commissioning plans/procedures and close-out processes
- Safety certification (e.g., NEBOSH/IOSH/OSHA-equivalent) and strong HSE mindset
Degree/HND/HNC in Electrical Engineering (or equivalent).
