We're looking for an experienced Senior Portfolio Delivery Manager to lead and manage a critical portfolio of transformation and technology initiatives for a major UK energy provider. This is a strategic role focused on shaping, guiding and delivering programmes that impact millions of customers - all while aligning with wider business and digital strategies.

About the Role

In this role, you will take full ownership of a complex, high-value portfolio - leading planning, governance, and execution across multiple workstreams. You'll ensure delivery stays on track to scope, time and budget, while safeguarding business outcomes and return on investment.

You will play a key role in shaping change direction, supporting long-term planning cycles, and ensuring delivery is aligned to both digital transformation and business unit strategies. You'll work closely with senior stakeholders and cross-functional teams across business and technology functions.

Key Responsibilities

• Manage delivery of the portfolio and associated projects, ensuring defined business outcomes and benefits are realised
• Own the overall portfolio plan, budget, scope, and prioritisation - proactively managing interdependencies and risks
• Lead the development of business cases, plans, impact assessments and operating models across wide-ranging change initiatives
• Establish and run portfolio governance, driving decisions and resolving obstacles with clear, accurate reporting
• Support the quarterly, annual, and 3-year strategic planning cycle for change, identifying strategic dependencies
• Ensure alignment of delivery with enterprise digital and business strategies
• Champion benefit realisation and ensure return on investment is optimised throughout the portfolio lifecycle
• Lead stakeholder engagement and change management activity to ensure smooth transition and adoption of change
• Manage relationships with internal delivery teams and third-party suppliers to ensure delivery to quality standards
• Build and lead high-performing, cross-functional teams, motivating and coaching others to deliver successful outcomes
• Conduct structured quality assurance and health check reviews across the portfolio as needed

What We're Looking For

• Extensive experience leading portfolios or large-scale programmes across business and IT
• Proven ability to manage complex budgets, governance, and stakeholder landscapes
• Strong understanding of change delivery methodologies (agile, waterfall, hybrid)
• Demonstrated experience working in or with regulated, customer-centric industries
• Outstanding leadership, planning, and communication skills
• Ability to lead through complexity and ambiguity, aligning delivery to strategic goals

Why Apply?

This is an opportunity to play a pivotal role in delivering business-critical change for a leading organisation with a national footprint. You'll join a collaborative team with strong executive backing and a clear mandate to transform and innovate.

The role is hybrid with just one day per week in Windsor - giving you flexibility alongside strategic impact.
