Project Manager

Role Summary: We are seeking a Project Manager / PMO, Site Delivery, Acceptance and Mobilisation, to join our fast-scaling team. In this role, you will take our sites from build through to service. In the first few months, you will lead on-site capital works and keep the build on track. After that, the focus moves to what happens once the build is finished: taking sites over from construction, getting them accepted and making them ready to go live. This is an opportunity to join a mission-led AI business redefining infrastructure, intelligence, and impact for enterprise customers. Key Responsibilities: Site delivery Track on-site works, contractors and suppliers against the plan. Deal directly with contractors on site and follow up on issues until they’re resolved. Check deliveries against what we ordered to ensure we know exactly what we’re signing for. Understand how the construction and commissioning schedule affects when a site is ready for equipment, and flag clashes early. Acceptance: Take over sites from the construction team once the build is complete. Run the acceptance checks: snag lists, test results and sign-off against what was agreed. Keep sites clean, safe and ready for testing and inspections. Mobilisation: Coordinate what’s needed to bring a site into service, working with the operations, technology and security teams. Ensure the handover to operations is clean, with nothing left open. Tracking and reporting: Keep site milestones, risks, actions and spend in one place, up to date and free of duplicates. Provide a short, clear site update for the weekly PMO pack, focused on the milestones that matter. Help build templates and checklists so each new site is quicker to set up than the last. Essential Experience: Experience of running or supporting construction, fit-out or capital works projects. Experience of handover, commissioning or bringing facilities into use. Good planning skills and experience of maintaining a risk log and action list. Comfortable working on site and dealing directly with contractors. Junior to mid-level project or PMO experience. We value hands-on delivery more than certifications. One or more would be an advantage: Data centre or critical facilities experience. Experience handing sites over from construction to the teams responsible for installing and operating the equipment. Some understanding of power, cooling and network readiness in a data centre. Experience in procurement, deliveries and goods received checks. Interest in AI infrastructure.
