The position

As a key member of our IT function, the PMO Manager will be assigned across different PMO offices and initiatives according to business need. This is a hands‑on senior role for someone who thrives in the detail - you will understand the work deeply enough to manage it credibly, not just report on it.

The role operates across three core areas of activity, and the balance will shift depending on where the business needs focus at any given time:

• Ensure plans are realistic, tracked, and owned - holding project managers and workstream leads to account in a constructive and credible way.
• Provide end‑to‑end oversight of the project portfolio, ensuring initiatives are delivered on time, within scope, and on budget, while achieving the desired outcomes.
• Lead regular portfolio reviews to ensure alignment with strategic objectives and the efficient use of resources.
• Provide a planning framework to allow critical resources to be managed across portfolio and within individual programmes.
