Job description

A leading international environmental and conservation-focused organisation is seeking an Interim Grants Finance Officer to support its London-based team for an initial three-month contract. With a pioneering funding model backed by a highly credible philanthropic founder, the organisation supports environmental partners across the globe— from small grassroots groups to established international NGOs—working to tackle some of the world's most pressing biodiversity challenges.

This is an exciting opportunity for someone with a strong understanding of risk and governance in a grant‑giving context to hit the ground running and play a key role in strengthening processes and ultimately helping to shape how this crucial function evolves.

As the Interim Grants Finance Officer your role will involve:

• Carrying out financial due diligence and organisational health assessments of grantee partners across a wide range of contexts, from those providing informal records to those with full audited accounts
• Reviewing financial documents, risk assessments, governance frameworks, and policies to ensure appropriate oversight is in place
• Liaising directly with partners to clarify risk‑related issues and make practical recommendations
• Supporting the Finance & Risk Manager by picking up day‑to‑day assessments, giving her space to review and refine broader processes and strategy
• Feeding into discussions around how to streamline and resource the function longer‑term

The ideal Grants Finance Officer will be:

• Experienced in grant‑making, particularly in international development or the charity sector, either as a funder or grantee
• Comfortable reviewing a wide spectrum of financial documentation and assessing organisational risk
• Skilled at communicating diplomatically and clearly across a range of cultures and contexts
• Happy to work autonomously and jump straight into the work
• Either a qualified accountant or qualified by experience (QBE) – the right background and approach are more important than letters

This role is available on a part‑time or full‑time basis (0.8 – 1.0 FTE), offering a day rate of £250 – £300, depending on experience. Hybrid working is in place, with three days per week expected in the Central London office.

This is a fantastic short‑term opportunity (with potential for extension) to join a values‑driven, globally‑minded organisation and contribute meaningfully to their mission while influencing how financial due diligence and risk are embedded for the future.
