Job description

As Senior New Business Manager, you will lead the new business function of our high-performing and ambitious Corporate Partnerships team. You will be responsible for driving new corporate income by identifying, cultivating and securing major partnerships. You will lead all new business activity with the New Business Manager, from proactive outreach and developing compelling propositions to successfully negotiating and onboarding new partners. 

Working closely with teams across the Charity and The Royal Marsden, you will create partnership proposals that align corporate objectives with those of the Charity. You will also lead long‑term strategic planning of the function, support the development of our Corporate Partnerships Board, and ensure the highest standards of reporting, forecasting and data management. 

This is a highly visible and impactful role, ideal for someone who combines creativity, commercial insight and strategic thinking with a passion for building relationships that create meaningful impact. 

Key responsibilities 

  • Lead the New Business function, building a strong pipeline and securing high‑value, multi‑year corporate partnerships. 

  • Drive income growth, meeting ambitious six‑ and seven‑figure annual and multi‑year targets while managing financial performance, budgets and forecasts. 

  • Develop and deliver compelling, tailored corporate propositions, collaborating across the Charity and hospital to create standout proposals and pitches. 

  • Support senior leadership, including maximising the value of the Corporate Partnerships Board and strengthening key internal stakeholder relationships. 

  • Oversee new partner onboarding, negotiating partnership agreements and ensuring a smooth transition to the Partnership Management team. 

  • Lead and develop the New Business Manager, providing clear direction and supporting their growth. 

About you

You will be an experienced and driven partnerships specialist, with a strong track record of securing high‑value relationships in the charity or commercial sector. Confident, creative, highly proactive and a natural leader, you will bring a blend of strategic thinking and hands‑on delivery.
 

You will bring:
 

  • Proven success in corporate fundraising or business development, ideally within the charity sector. 

  • Excellent communication and relationship‑building skills, with the ability to engage confidently with senior stakeholders. 

  • Strong negotiation and influencing ability, with experience delivering high‑impact pitches and presentations. 

  • Creative and strategic thinking, with a flair for writing compelling proposals. 

  • Strong organisational, analytical and planning skills, with the ability to manage multiple priorities. 

  • A collaborative, solution‑focused approach and the confidence to work both independently and as part of a high‑performing team. 

What we offer: 

  • Competitive salary of £45,000-£50,000 

  • Hybrid working between home and Chelsea with occasional travel to Sutton 

  • Flexible working around our core hours of 10am to 4pm 

  • 27 days annual leave rising with length of service 

  • Training, support and development opportunities 

  • Access to the Blue Light discount scheme and other discounts opportunities 

  • Range of wellbeing initiatives including access to an employee assistance programme designed to save money and improve your physical, financial and mental health and wellbeing, access to free online GP appointments and free eye tests and contribution towards any glasses required for work purposes 

  • Opportunities for training and career development. 

Inclusion matters 

We are committed to building a diverse and inclusive workforce that reflects the communities we serve. We welcome applications from all backgrounds and walks of life. 

If this sounds like the opportunity for you, we’d love to hear from you.
