Job Description

We're supporting a fast-growing international NGO working save the lives of children through avoiding a preventable cause of childhood death. Following a period of significant growth and multi-year philanthropic funding, the organisation is now strengthening its internal finance capability to support delivery across 40+ countries, with further expansion planned.

This is an opportunity for an experienced Finance Controller to work either remotely or from their London-offices and play a central role in building structure, rigour and confidence in financial information during a critical phase of growth.

Key responsibilities:

  • Own the quality and integrity of financial records, including balance sheet and donor / restricted fund accounting
  • Lead and embed a predictable, high-quality month-end close process
  • Ensure financial information is audit-ready and support external audits and statutory reporting
  • Strengthen financial controls, identifying and addressing gaps in a pragmatic, proportionate way
  • Support oversight of payments and banking activity, ensuring appropriate authorisation and audit trails
  • Act as a key owner of finance systems, data standards and core finance processes
  • Support improvements to systems, workflows and documentation as the organisation scales
  • Work closely with the Head of Finance and Finance Business Partner to ensure financial data supports forecasting, donor reporting and decision-making

About you:

  • Qualified accountant (ACA / ACCA / CIMA) or equivalent experience
  • Strong background in financial control, reporting and audit readiness
  • Experience working in charities, NGOs or multi-funder environments is highly desirable
  • Comfortable operating in small, evolving organisations and building structure where needed
  • Confident communicator, able to work effectively across teams and time zones

The role is a six-month contract initially and is expected to be part-time initially (around three days per week), with strong potential to become permanent and possibly full-time as the finance function continues to mature.
