About the Role

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

* 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?
