Senior Finance Officer (Part-time)

WePlanet is entering a phase of organisational growth that requires stronger financial modelling, forecasting, and financial planning systems to support responsible expansion and strategic decision-making. 

We are seeking a Senior Finance Officer (part-time) to help strengthen our financial planning and analysis capabilities. This role focuses on forward-looking financial modelling, cashflow forecasting, grant financial planning, and financial risk monitoring. 

Working closely with the Secretary General, the Senior Finance Officer will help ensure leadership has the financial insight needed to plan hiring, manage grant funding, and support the organisation's long-term sustainability. 

This role is particularly suited to someone who enjoys building financial models, translating financial data into strategic insight, and working in a small, distributed organisation where financial planning plays a critical role in decision-making. 

The role is remote and part-time, with an estimated commitment of 16–20 hours per week during the first 3–4 months, reducing to approximately 8–12 hours per week once systems and processes are established. 

Applications will remain open until the position is filled, but priority will be given to candidates who apply promptly and are available to start at the earliest opportunity.
