Job description

Project Coordinator

Location: London, with travel across Europe · Reports to: Delivery Manager · Team: Delivery

Company Overview:

Radiant is redefining how AI infrastructure is built.

We design and operate AI-native cloud platforms engineered for sovereignty, performance, and scale. Our infrastructure powers GPU-native workloads, multi-tenant control planes, and high-performance AI systems designed for the most demanding environments.

We are not building a generic cloud. We are building purpose-built AI infrastructure — from powered land, to compute, to software.

As we scale, we're building this organisation from the ground up. We're looking for people who'd rather build the playbook than inherit one — who are comfortable doing the work themselves as well as directing others, and who can adapt as fast as our strategy does. This is a startup model: attitude and adaptability matter more to us than years of experience or the size of team you've previously managed.

This is a client-side role supporting our Delivery Manager across data centre construction projects, with exposure to executive stakeholders, EPCs, contractors, cost consultants, equipment OEMs, and the teams receiving each completed site.

What You'll Do

You'll own governance and reporting across Radiant's live construction projects, for all RIBA stages, supporting multiple sites across regions from our London base. You'll work directly with the Delivery Manager, running the project controls and taking ownership of building new ones where gaps appear.

Key Responsibilities

Programme and Governance

• - Own the governance cadence — agendas, pre-reads, minutes, action logs and decision registers — and chase overdue items without waiting to be asked.
• - Track programme milestones, stage gate criteria and critical path dependencies across multiple sites, flagging slippage early.
• - Maintain risk and issue logs, making sure every item has an owner, a mitigation and a date.

Procurement and Contractors

• - Track long-lead items against programme dates and elevate risk to energisation early.
• - Be the day-to-day interface with contractors and consultants: progress meetings, RFIs, submittals and change requests.

Cost

• - Keep a close eye on monthly costs against budget, tracking forecasts and change across each site.
• - Review interim payment valuations submitted by the Project Manager and cost consultant ahead of our approval, checking them against progress, programme and budget, and raising queries early.

Reporting and Information

• - Produce clear regular reporting for senior stakeholders.
• - Keep project documents, drawings and correspondence organised and easy to find.

Build the playbook

• - Help define Radiant's project controls templates, reporting standards and lessons-learned routines from scratch.

What You Bring:

• - Attitude matters more to us here than number of years of experience.
• - Experience in construction projects, on the contractor, consultant or developer side.
• - A working understanding of the design and construction lifecycle (RIBA Stages 2–6 or equivalent).
• - Comfort with numbers — budgets, forecasts and payment valuations — and the confidence to question them.
• - Comfort building routines and templates from experience rather than inheriting mature ones.
• - We're hiring for the instinct to spot problems early and follow them through, not years of managing a project office.
• - Clear writing and confidence chasing contractors, consultants and suppliers.
• - Willingness to travel to sites across Europe at short notice as projects demand; this is not a purely desk-based role.

Preferred Skills (Nice to Have):

• - Data centre or other mission-critical infrastructure experience.
• - Familiarity with scheduling and document control tools.
• - APM PMQ, PRINCE2, or equivalent.

Qualities we look for:

• - Set the standard: Every single day, you spot opportunities to constructively shake things up.
• - Inspire the change: There's no blueprint for the future. You'll embrace challenges and change.
• - You're real and you're true to yourself: We cherish and celebrate diversity so you'll feel right at home whoever you are and whoever you're talking to, you treat everyone the same.
• - Get stuck in: You'd rather be building than overseeing. Our strategy will keep evolving, and so will you — attitude and adaptability matter more to us than a fixed playbook or a big team behind you.
