• Leading commissioning activities across MEP, controls, life safety and specialist systems, including wet/dry, hot/cold and live/dead testing and full Integrated Systems Tests (IST).
• Ensuring all systems are tested, verified and documented to meet design intent, client performance requirements, regulations and uptime standards.
• Coordinating with design teams, vendors, subcontractors and project delivery teams to integrate commissioning requirements into project planning and delivery.
• Managing commissioning teams and specialist vendors, overseeing functional testing, performance validation and completion of commissioning records.
• Supporting client training, O&M documentation, test certificates and as-built information to enable a smooth and fully evidenced handover.
• Identifying risks and opportunities throughout the commissioning process and working proactively to deliver commercial and technical value.

• HND minimum in Electrical, Mechanical, Building Services or Controls Engineering (BEng Hons or equivalent preferred).
• 10+ years' experience operating as a senior commissioning manager.
• Incorporated Engineer status with MCIBSE, MIET or equivalent.

• Proven track record delivering complex commissioning programmes.
• Familiarity with industry standards such as ASHRAE, BSRIA, Uptime Institute and NFPA.

• Excellent leadership, communication and stakeholder management skills with the ability to coordinate multiple parties and manage deadlines.

Desirable:

• Chartered Engineer status (CEng FCIBSE, FMIET).
• CxA certification or equivalent commissioning qualifications.
• Experience in data centres, high-technology or industrial facilities.
• Experience with BIM/Revit, Navisworks and commissioning/project management software tools.

What's In It For You?

• Competitive salary of £80,000–£100,000 (based on experience).
• Hybrid working arrangement with office base in Corsham and travel to cutting-edge project sites.
• Opportunity to take a lead technical role across flagship, mission-critical projects in data, defence and energy sectors.
• Work within a business that is genuinely "built around people", investing in wellbeing, work-life balance and long-term career development.
• Inclusive, values-driven culture focused on teamwork, innovation and delivering exceptional work, not just ordinary.
• Support for professional development, further qualifications and progression within a growing, technically strong organisation.
