Senior Mechanical Commissioning Engineer - Data Centres

We’re thrilled to announce that, due to recent project wins, we have several exciting roles opening up across our team, all of which are available to start immediately

We’re specifically interested in hearing from candidates with strong data center experience, so if this is your area of expertise, we’d love to connect.

If you’re ready to take the next step in your career, we’d love to hear from you.

The Role:

The CX Mechanical Engineer is responsible for the planning, execution, and management of commissioning activities for mission-critical mechanical systems within hyperscale data center environments. This role ensures that all mechanical and thermal infrastructure is installed, tested, integrated, and handed over in full compliance with project requirements, safety standards, and operational objectives, supporting high-availability and energy-efficient operations.

The responsibilities for this role include, but are not limited to, the following:

Commissioning Management

• Lead and manage the end-to-end commissioning process for mechanical systems, from pre-functional testing through integrated systems testing (IST) and final handover. • Ensure commissioning activities are executed in accordance with approved commissioning plans, project schedules and quality standards. • Coordinate phased and systems-based commissioning strategies typical of hyperscale delivery model

Mechanical Systems Testing & Validation

Commission and validate critical mechanical infrastructure, including but not limited to:

• Chilled water systems (chillers, pumps, cooling towers, heat exchangers) • Airside systems (CRAC/PAHUs, AHUs, FWUs) • Direct-to-chip, liquid cooling, or hybrid cooling systems (where applicable) • HVAC distribution systems (ductwork, piping, valves, dampers) • Fuel oil and lube oil systems supporting standby generation • Make-up water, water treatment, and blowdown systems • Verify system performance under normal, abnormal, and failure conditions. • Validate thermal performance, capacity, control response, and efficiency against design intent and client requirements.

Project Coordination & Oversight

• Plan, coordinate and lead mechanical commissioning activities in collaboration with design engineers, construction teams, vendors, controls specialists and operations stakeholders. • Act as the primary technical authority for mechanical commissioning issues on site. • Support construction readiness, system turnover and commissioning sequencing in fast-track hyperscale environments.
