Job description

Era4 develops, owns and operates AI infrastructure across the UK, powered by renewable energy.

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

• 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.
• 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.
• 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.

Why Join Era4

You’ll be joining a mission-driven start-up building critical national infrastructure, where operational excellence directly enables growth. This role offers high visibility with leadership, real autonomy, and the chance to shape how a next-generation company operates at scale.
