Senior Mechanical Engineer in England

We are seeking an experienced Senior MEP professional to lead the mechanical, electrical, and public health (MEP) delivery of large-scale data centre developments. This role is critical to ensuring mission-critical infrastructure is designed, coordinated, and delivered to the highest standards of reliability, resilience, and efficiency.

The successful candidate will provide technical leadership across the full project lifecycle — from concept and early-stage design through procurement, construction, commissioning, and handover — working closely with clients, designers, contractors, and operations teams.

• Technical Leadership: Lead all MEP aspects of data centre projects, including power distribution, UPS systems, generators, cooling strategies, BMS, fire systems, and resilience architecture. Ensure compliance with relevant codes, standards, and best practices (e.g. TIA-942, EN, IEC, ASHRAE, Uptime Institute principles). Review and challenge MEP designs to achieve optimal availability, redundancy, and energy efficiency (PUE).
• Design Management: Manage and coordinate MEP consultants throughout concept, schematic, detailed design, and IFC stages. Drive design decisions related to topology (N, N+1, 2N), scalability, and future expansion. Ensure full multidisciplinary coordination with structural, architectural, and civil teams.
• Delivery & Construction: Oversee MEP procurement strategies, including early contractor involvement and long-lead equipment. Monitor construction progress, quality, and compliance with specifications. Resolve complex technical issues and manage change efficiently.
• Commissioning & Handover: Lead and coordinate Level 1–5 commissioning, IST, and integrated testing activities. Ensure systems are fully validated, documented, and handed over in line with client and operator requirements. Support operational readiness and smooth transition to facilities management.
• Stakeholder & Commercial Management: Act as a key technical interface between client, funders, contractors, and operators. Provide input into budgets, programmes, risk registers, and value-engineering exercises (without compromising resilience). Support technical due diligence for acquisitions or new site developments.

• Essential: 10+ years’ experience in MEP delivery on mission-critical or complex infrastructure projects. Proven experience delivering data centres, hyperscale facilities, or equivalent high-reliability environments. Strong understanding of electrical and mechanical systems for high-density loads. Experience managing complex commissioning and integrated systems testing. Excellent stakeholder management and leadership skills.
• Desirable: Degree in Mechanical, Electrical, or Building Services Engineering (or equivalent). Chartered Engineer status (CEng / PE or equivalent). Experience working with hyperscale, colocation, or edge data centre operators. Exposure to sustainability strategies, energy efficiency, and low-carbon solutions.

• Decisive and technically confident, with a calm approach under pressure.
• Commercially aware, with a strong understanding of risk and programme drivers.
• Detail-oriented yet capable of taking a big-picture, system-level view.
• Comfortable working in fast-paced environments with demanding clients.

What We Offer: Opportunity to work on high-profile, critical infrastructure projects. Competitive salary and benefits package. Long-term career progression within a growing data centre delivery platform. Exposure to end-to-end development, from greenfield sites to live environments.
