About us 
At Macmillan you'll find talented people working together to do whatever it takes to support people living with cancer. We're going all out to find even better ways to help even more people who need our support. Our values are at the heart of who we are and everything we do, inspiring our thinking and guiding our actions. 

About the role:

Macmillan is expanding it’s work in Social Investments where we invest in cancer-related healthcare projects to improve the wider healthcare system. We currently back around 15 UK-wide projects, with successful sites repaying us so we can reinvest the funds to help even more people with cancer. 

We are looking for an exceptional Senior Finance Business Partner to play a key role in supporting our Social Investments. You’ll partner closely with the System Investments team who work directly with NHS colleagues — so an understanding of NHS accounting or NHS financial frameworks would be a real advantage.

In this role, you’ll act as a trusted adviser, providing expert financial insight, challenge and guidance to support strategic decision‑making. You’ll lead on quality assurance, support with social investment negotiations and carry out financial planning and modelling based on outcome contracts. You’ll feed into budgeting, forecasting and monthly reporting, build strong relationships with senior stakeholders, and ensure financial plans align with Macmillan’s long‑term goals.

You’ll analyse performance and provide clear, evidence‑based recommendations that help teams make the best use of resources. You’ll also support key programmes and projects, contribute to cross‑finance initiatives, and champion continuous improvement in our financial systems and ways of working.

About you:

You’ll bring:

• A recognised accountancy qualification (CIMA, ACCA, ACA or equivalent).
• Strong business partnering experience, ideally in a complex organisation.
• Confidence influencing senior stakeholders and providing robust financial challenge.
• Experience in management accounts, financial modelling and strategic costing.
• Advanced Excel skills and strong data literacy.
• Excellent communication skills and a collaborative, solutions‑focused approach.
• The ability to work under pressure, manage competing priorities and deliver high‑quality outputs.
• Knowledge of and/or an interest in Social Investment and outcome-based contracts
• Experience of NHS accounting and frameworks (desirable but not essential)

This is a fantastic opportunity to shape a growing area of Macmillan’s work and ensure our resources deliver the greatest possible impact for people living with cancer.
