The Role

The Business Manager is a senior cross‑cutting role working in close partnership with FILEs Senior Leadership Team (SLT) to enable and enhance strategic alignment, organisational effectiveness and cross‑functional collaboration. This role balances strategic insight with operational excellence ensuring the SLT works as effectively as possible while driving delivery on organisational priorities.

This is a highly facilitative cross‑functional role requiring exceptional judgement, communication and organisational skills. It operates with a birds‑eye systems‑level view of the organisation acting as the connective tissue that keeps the SLT aligned. The role balances a forward‑looking strategic perspective with hands‑on operational execution. The postholder will work across teams to identify challenges and opportunities, manage critical projects, facilitate decision‑making and champion a culture of transparency, collaboration and accountability.

Key Responsibilities

• Strategic Partner to Senior Leadership Team: Work with the SLT as a thought partner to drive clarity, alignment and execution on organisational priorities including planning cycles, workflow management and organisational performance reviews.
• Operational Leadership and Execution (SLT): Lead operational cadences (SLT meetings, offsites, quarterly reviews and strategic planning sessions) and manage cross‑functional initiatives and 2026; this will include supporting the development of FILEs 2027‑2030 organisational strategy.
• Confidential & Complex Decision Support: Handle highly confidential issues such as legal, financial or organisational change initiatives with discretion and maturity. Provide quality recommendations to support complex and confidential decision‑making.
• Support Team Leadership & People Management: Manage, empower and develop the Executive Assistant team ensuring strong support for the SLT and fostering a collaborative, high‑performing leadership culture.
• Cross‑Functional Coordination and Collaboration: Enable effective communication and coordination across teams ensuring alignment and follow‑through on organisational priorities.

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 onward grants to partners who align with FILEs 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.
