Reporting to the Group TMO Director , you’ll play a pivotal role in overseeing and coordinating transformation across our Group Functions portfolio , bringing together governance, investment, performance, benefits, risk and reporting to provide a clear view of portfolio delivery.

•Lead portfolio governance - manage the governance cycle for the Group Functions Portfolio Board, ensuring clear decision-making, effective stage-gate governance and alignment with Group standards.

•Support investment decisions - review business cases and investment proposals, providing assurance over quality, completeness and readiness for approval.

•Manage portfolio risks and dependencies - maintain an integrated view of key risks, issues and cross-portfolio dependencies, ensuring timely escalation and resolution.

•Drive portfolio maturity - continuously improve governance, reporting, tools and ways of working, embedding leading portfolio management practices across Group Functions.

•Connect the portfolio - act as a central point of coordination across transformation teams, helping leaders see the bigger picture and make informed portfolio-level choices.

Here's what we're looking for:

You’ll bring significant experience of portfolio management, transformation governance or Enterprise PMO/TMO delivery within a large, complex organisation, together with:

•Strong analytical and numerical skills, with the ability to turn data into meaningful executive insight.

•Experience producing high-quality Board and senior leadership reporting .

•Experience supporting enterprise-scale transformation and improving portfolio management capability.

•A practical, continuous-improvement mindset and a passion for making governance simpler, clearer and more effective.

Location:

We operate a Flexible First approach, empowering colleagues to work in the way that works best for them. The role can be predominantly home-based, but flexibility to travel to our Reading site when required will be needed.

This is an opportunity to join the TMO at an exciting point in our transformation journey. You’ll have the chance to work across a broad and evolving portfolio, influence how transformation is governed and managed, and help build a portfolio capability that supports better decisions and stronger delivery.

If you enjoy bringing structure to complexity, creating insight from data and helping senior leaders make better portfolio decisions, we’d love to hear from you.
