This is an exciting opportunity for an ambitious fundraiser to establish a robust mid-value (£10k-£99k) programme and pipeline of trusts, foundations, and National Lottery agencies. You will play a vital role in filling a gap in our current portfolio and will be supported by the Trusts & Statutory Fundraising Manager to build the new programme from the outset.
About the role
As part of the Trusts & Statutory team, you will sit within the Philanthropy & Partnerships department; a collaborative and creative collection of teams who are committed to diversifying the charity’s income.
The core function of your role will be to develop and manage a new programme of mid-value (£10k-£99k) trusts, foundations, and National Lottery agencies to increase income for both project and core activities. This will include researching and building a pipeline of prospects, preparing high-quality written proposals and reports, and delivering excellent stewardship. You will account-manage a small cohort of existing donors, delivering on contractual agreements and strengthening the relationships long term.
You will liaise closely with colleagues across services, research, and campaigning to gather the necessary project information, data, case studies, and outcomes for use in your applications and impact reporting.
About you
If your knowledge, skills and experience include the following then we’d love to hear from you:
- A great communicator, who can write well, listen to others, and effectively present complex information.
- Proactive, well-organised, and able to work autonomously when required.
- Demonstrable experience of working in a similar role or a desire to develop transferrable skills.
- Experience of writing bids, applications, or proposals.
- Experience in preparing detailed reports and using data to demonstrate impact.
- Experience of undertaking in-depth research and developing targeted proposals for presentation to prospects.
- Experience of developing and maintaining long term relationships with supporters or clients.
- Experience of securing and managing mid-level (£10k-£100k) gifts from trusts, foundations and National Lottery sources.
*As a hybrid worker the expectation is that you will spend around 40% of your working time in our office spaces or working in community settings. As an inclusive employer we will consider home-based working for anyone where office-based hybrid working would be a barrier to being able to work for us, for example for someone living with a long-term health condition or disability.
