Senior Philanthropy Officer in London

Who we are: Hope is here. The Global Returns Project (GRP) is a UK charity unlocking new philanthropy to deliver urgent solutions for our planet. We are a fast-moving nonprofit that makes donations to high-impact nature and climate charities simple – and we don’t take any fees. We’ve already mobilised over £3 million for top environmental solutions and are working to unlock at least £30 million annually by the end of the decade. We are growing quickly: Last year's annual fundraising was 275% higher than the previous year.

The problem: Charities protecting our planet can turn the tide on climate change and nature loss. They have the skills, strategies and networks to deliver fast and global impact. But less than 2% of philanthropy goes to climate mitigation.

Our solution: In the UK alone, around £2 trillion sits with “HNW” individuals – those holding between £100k and £30 million. Yet traditional philanthropy largely overlooks them. We’re unlocking this funding by offering trusted, pro bono advice and a simple, portfolio approach to giving. Our expertise in UK wealth advice offers a unique path to scalability and systems-change.

What we are looking for: We’re looking for a confident, capable fundraiser to play a key role in major-gift fundraising – helping to secure transformational support from high-net-worth individuals. You’ll manage your own portfolio of prospects and donors, contributing across the full fundraising cycle: prospecting, cultivation, making direct asks, closing and stewardship. Alongside this, you’ll support the development of relationships with wealth advisers to generate referral leads, while also prospecting independently for major gifts.

The ideal candidate will be excited to build networks of wealth managers, private-client teams and other advisers to HNWIs, and to convert adviser introductions into committed support. You’ll complement this with proactive outreach to identify and engage new major donors beyond existing referral channels.

To succeed, you’ll develop strong fluency across three distinct fundraising pitches: a business case for advisers; an impact case to persuade donors to support our portfolio charities; and a systems-change case to win backing for GRP’s operating costs (salaries, office costs, etc) to keep the charity running fee-free. You’ll be comfortable making direct asks for funding, ideally with experience of securing significant gifts or multi-year commitments. You’ll be hands-on in day-to-day fundraising activity and able to manage multiple relationships and priorities effectively. You’ll thrive in a small, fast-moving team—taking initiative, being collaborative, and contributing to shared goals. Crucially, you’ll care deeply about climate and nature.

Experience required: Strong experience in frontline fundraising (as a guide, likely 3-6 years).

Location: Centrally located, light and airy office on Regent Street, London. Estimated two days per week in the office.

Benefits: 20 days’ annual leave (pro-rata), plus statutory bank holidays (pro-rata). Occasional 1–2 days’ additional paid leave over Christmas period. Flexible working.
