MEP/Commissioning Site Lead

Job Description

We're partnering with a well-funded, rapidly growing data center developer looking to appoint a experienced MEP Commissioning Site Lead to support a major development in Phoenix, AZ.

Backed by an established investment firm with significant assets under management, the business is building its presence across some of the most sought-after data center markets in the US, with an active development pipeline spanning Arizona, Virginia and California.

Unlike developers focused on building gigawatt-scale portfolios, this business is taking a more targeted approach, developing high-quality, mission-critical facilities in established Tier 1 markets.

With an experienced leadership team recruited from some of the industry's most recognised data center developers and operators, this is an opportunity to join at an early stage, take ownership of significant projects and play a key role in shaping the company's delivery capabilities.

The Role

I'm looking for an MEP Commissioning Site Lead who can take ownership of commissioning activities across a large-scale data center development, ensuring that mechanical, electrical and critical infrastructure systems are delivered, tested and commissioned to the highest standards.

Working on behalf of the developer, you'll be responsible for overseeing commissioning activities from construction and fit-out through to testing, integrated systems testing and final handover.

You'll work closely with general contractors, commissioning agents, engineering teams and other key stakeholders to ensure facilities are delivered safely, on schedule and in line with tenant requirements.

This is a hands-on, site-based position suited to individuals who enjoy being close to project delivery and taking accountability for results.

Key Responsibilities

• Lead and oversee MEP commissioning activities across large-scale, mission-critical data center developments.
• Represent the developer throughout the commissioning process, ensuring contractors and commissioning agents meet project requirements.
• Coordinate mechanical, electrical and critical infrastructure testing, including integrated systems testing (IST).
• Monitor commissioning schedules, identify potential delays and proactively resolve technical or delivery challenges.
• Work closely with general contractors, engineering teams, commissioning providers and tenant representatives.
• Ensure all commissioning activities comply with project specifications, quality standards and operational requirements.
• Oversee commissioning documentation, testing procedures, issue tracking and final handover deliverables.
• Support the transition from construction and fit-out through to operational readiness.
• Provide regular progress updates to project leadership, highlighting risks, milestones and areas requiring attention.
• Help establish effective commissioning processes and delivery standards as the business continues to expand.

What We're Looking For

• Strong experience in MEP commissioning within mission-critical environments, ideally hyperscale or large-scale data center developments.
• Previous experience working for a data center developer, owner/operator, commissioning consultancy or specialist mission-critical contractor.
• A strong understanding of the full data center construction lifecycle, from initial construction through fit-out, commissioning and handover.
• Technical knowledge of critical electrical and mechanical infrastructure, including power distribution, UPS, generators, cooling systems and associated controls.
• Experience overseeing general contractors, subcontractors and third-party commissioning agents.
• Familiarity with commissioning levels, functional performance testing and integrated systems testing.
• Strong communication and stakeholder management skills, with the ability to represent the owner's interests on-site.
• A proactive, delivery-focused approach and the ability to work independently within a growing organisation.

Owner-side experience would be particularly valuable, although we're equally interested in speaking with candidates from GC or commissioning backgrounds who have delivered complex mission-critical projects.

Why Consider This Opportunity?

You'll be joining a business at a pivotal stage of its growth, with the financial backing, development pipeline and industry expertise to deliver significant projects across the US.

The company is deliberately building lean, experienced teams, giving individuals genuine responsibility and the opportunity to influence how projects are delivered.
