radiant - Principal Programme Manager

• You have run large, integrated delivery programmes where construction, hardware and software all had to land together. That is the core of this role, and it is what we are hiring for. • Strong track record running infrastructure or data centre delivery programmes at scale, with many vendors and dependencies live at once. • You hold a master schedule in your head and on the page, manage the dependencies and the residual schedule risks. • You set the order of operations first and dates second. You press partners for the prerequisites, not just the deadline. • You write clearly and report plainly. Leadership reads your update and the status/actions are clear. • You build the process, and you keep it light enough that people actually use it. • You bring teams together across disciplines and hold the plan, comfortable as the point of contact without becoming a bottleneck. • You have built or grown a PMO function, or you are ready to. • We are not asking for deep AI or GPU knowledge. We have that in the team, and you will pick up what you need quickly. We care far more about your judgement as a programme manager. • Exposure to HPC, GPU clusters, or liquid-cooled high-density deployments. • Experience with GPU reference architectures, OEM delivery, or co-location fit-outs. • Familiarity with Jira as a delivery tool. We run our schedules there. • A relevant certification (such as APM, PRINCE2 or PMP), though experience matters more. • HOW WE'LL BACK YOU • A direct line to the CTO and the senior team. You are not buried in the org. Your work is seen. • The mandate to build the function your way, within clear standards we agree together. • Dedicated support from day one, so you start on the strategy and the build rather than the backlog. • The budget and backing to grow the team as the estate scales. • A business that moves quickly and gives you real scope from week one.
