About FILE
 The Foundation for International Law for the Environment (FILE) is a not-for-profit philanthropic organisation working to accelerate legal action on climate change.
 

Through grant-making and in-house legal expertise, we empower our partners to deliver strategic, innovative legal interventions and we support lawyers in their own countries to bring their own cases.

Legal action can unlock the systemic changes in finance, policy and social systems needed to protect all of us from climate change. The power of the law is both direct (changing policy and practice) and indirect (signalling the wider shifts taking place across these systems).  

FILE is a ‘regrantor’ - this means we do not bring legal action in our own name. We receive grants from our philanthropic donors and make onwards grants to partners who align with FILE’s charitable aims and purposes. We do not seek to make any profit from our activities either in a relevant financial year or in the longer term.  

The Role

We are looking for an exceptional interim finance leader to join FILE during a period of organisational transition, as we shape our strategy for the next three years and review our long-term leadership structure. 

This is a strictly interim appointment, created to provide visible senior leadership across our Finance function while FILE undertakes a wider review of its long-term organisational design and permanent leadership arrangements. 

As Interim Director of Finance, you will be a key member of the Senior Leadership Team, partnering closely with the Executive Director, Supervisory Board, and senior leaders to ensure strong financial stewardship and sharp strategic insight. You will lead a talented finance team and help build the foundations for our future operating model. 

This is an opportunity for a senior finance leader who enjoys combining financial rigour with strategic influence, is energised by complexity, and is motivated by helping an ambitious organisation maximise its impact on climate justice and environmental law. 

The role spans across four core areas: strategic and team leadership, financial strategy planning and analysis, finance operations and systems, and risk and compliance.

Key Responsibilities

Strategic and Team Leadership (20%) 
As an interim Senior Leadership Team member during a period of organisational change, you will ensure the development, delivery and assessment of FILE's Strategic Plan, supporting collective SLT decision-making and accountability. You will advise the Executive Director and boards on financial governance, lead a high-performing finance team, provide independent challenge to strategic decisions, and represent FILE with auditors, banks, donors and other external stakeholders. 

Financial Strategy, Planning and Analysis (30%) 
You will hold overall accountability for FILE's long-term financial planning, budgeting, scenario modelling and reporting, ensuring financial sustainability and acting as a thought partner to senior leadership and boards. This includes supporting fundraising and grantmaking with high-quality financial insight, stewarding donor funds effectively, and maintaining a reserves strategy aligned to FILE's mission and risk appetite. 

Finance Operations and Systems (20%) 
You will hold overall accountability for finance operations including compliance, taxation, audit and treasury management, with day-to-day execution delegated to the Head of Finance. Responsibilities include cashflow forecasting, foreign exchange and banking relationships, and supporting the development of a finance systems roadmap to harmonise platforms across the FILE network. 

Risk and Compliance (30%) 
You will lead financial risk identification, assessment and mitigation across the organisation, overseeing the development, implementation and evaluation of finance policies and procedures to ensure consistent compliance with relevant local laws, tax regulations and donor requirements, underpinned by strong internal and external assurance including statutory and donor audits.
