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 Cancer Support is recruiting a Volunteering Mass Engagement Manager for a 12‑month family‑leave cover role — a unique opportunity to shape the future of how thousands of people give their time to support people living with cancer.

This role is one of four Volunteering Mass Engagement Manager posts, but with a distinct and exciting focus. Rather than directly line‑managing the Volunteering Mass Engagement Leads, you will provide matrix management and day‑to‑day support as they deliver our calendar of face‑to‑face events and our micro‑volunteering programme.

Your primary responsibility will be to design, develop, test and launch a brand‑new mass‑engagement volunteering product — a simple, flexible, light‑touch way for people to “give time” that can inspire a lifetime of support for Macmillan. Over the course of the 12‑month contract, you’ll take this product from concept to large‑scale launch, before transitioning it into business‑as‑usual delivery.

Alongside this innovation work, you’ll also step in to support wider team needs, including event delivery, volunteer engagement and occasional line‑management cover, ensuring smooth operations during busy periods or staff absence.

What you’ll be doing

• Leading the end‑to‑end development of a new mass‑engagement volunteering product, from insight and design through to testing and national rollout.
• Working in an agile approach to quickly identify the challenge and the best ways to resolve it.
• Working with teams from across fundraising, innovation, digital and customer experience to get to the best outcomes fast.
• Testing and learning, adapting our approach to overcome unexpected challenges and obstacles. 
• Providing matrix management and expert support to Volunteering Mass Engagement Leads across events and micro‑volunteering activity.
• Coordinating inclusive volunteer journeys and ensuring volunteers feel supported, valued and connected.
• Working with colleagues across Fundraising, Advocacy, Corporate Volunteering and Events to create opportunities that are accessible, exciting and easy to join.
• Supporting impact measurement, data capture and continuous improvement across mass‑engagement volunteering.
• Responding flexibly to team needs, including covering events and stepping into line‑management responsibilities when required.
• Building strong relationships with Lead Volunteers and supporting the delivery of high‑quality, high‑reach volunteering experiences.

About you

You bring:

• Strong project management skills and an innovation mindset — able to take an idea from concept to delivery at scale.
• Experience managing volunteering in a fundraising or mass‑engagement environment
• Confidence working collaboratively and influencing across teams and stakeholders.
• Knowledge of volunteering best practice, including legal, compliance and EDI considerations.
• The ability to prioritise, make sound decisions and stay calm under pressure.
• Experience supporting events and managing volunteers, with the ability to step into line‑management when needed.

What you’ll achieve

• A new, scalable volunteering product that brings tens of thousands more people into the Macmillan community.
• A smooth, inclusive volunteer experience across events and micro‑volunteering.
• Strong collaboration across teams and a culture of continuous improvement.
• Increased reach, impact and income through volunteering

In return, we offer a range of benefits including: 

• 25 days holiday plus flexible bank holiday options, increasing by 1 day every year of service up to 30 days  
• Pension matched up to 7.5% 
• 120+ learning and development offers, with access to external professional qualifications 
• Flexible working patterns, such as compressed hours, flexibility to work earlier or later around our core working hours of 10am-4pm 
• Holiday buying and selling scheme, life insurance, free wills, retail discounts and much more
