Portfolio Manager - Inspire Millions Strategic Portfolio
We’re looking for an experienced Portfolio Manager to help shape, coordinate and enable the delivery of the National Trust’s Strategic Portfolio for Inspire Millions – one of our key goals of our ten-year strategy.
You’ll play a pivotal role in enabling the work of the portfolio, helping senior stakeholders navigate challenges, understand risks and dependencies, maintain momentum and stay focused on delivering outcomes.
What it's like to work here
You’ll work as part of our Communications & Fundraising Directorate, supporting a Strategic Portfolio and reporting to a Head of Planning & Programmes, with a functional connection into the Strategic Portfolio Office.
As a member of our wider portfolio, programme and project management community, you’ll have opportunities to share learning, develop best practice and contribute to the continued evolution of strategic delivery across the Trust.
Your contractual location will be our head office in Swindon and there will be an expectation for you to attend the office. However, there is flexibility on where you are based at other times. You will be required to work at a National Trust location for 40-60% of your working week. This will be discussed in more detail at interview.
What you'll be doing
You’ll help ensure that the Inspire Millions Strategic Portfolio operates efficiently, effectively and in line with agreed governance and delivery frameworks.
The portfolio includes a number of key strategic initiatives to transform how we reach and connect with new and more diverse audiences so we can inspire millions of people to connect with nature and culture, turning inspiration into meaningful engagement and impact for our cause. Through reimagined content, powerful storytelling and inclusive calls to action – including a major fundraising appeal - we aim to engage people wherever they are, build shared momentum and inspire large‑scale change.
