Job description

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.

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.

Diversity & Inclusion:

Era4 is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
