Financial Controller (Client Funds)

The following information aims to provide potential candidates with a better understanding of the requirements for this role.

Role Purpose: This role sits at the heart of our financial controls at the Social Change Nest and combines cash management oversight, payment operations and financial compliance. However, this is not a traditional Financial Controller position. You will work with the team to ensure robust financial controls, accurate reconciliations, secure payment processes and transparent reporting for our diverse portfolio of social impact clients. You will also be a key driver of operational improvement, identifying better ways of working as we scale.

About the Social Change Nest: The Social Change Nest (SCN) is a fiscal hosting organisation that removes the financial and administrative barriers preventing grassroots groups and informal movements from accessing funding. Since 2021, we have supported 700+ groups across the UK and internationally, helping them access over £50 million in funding for causes ranging from climate and housing to racial justice and social wellbeing. We also work closely with funders, providing Grant Distribution and Fund Management services, enabling us to support social action with confidence and transparency. We are at the forefront of fiscal hosting in the UK!

We’re a growing business operating at pace. We’ve established a lot – but as we grow, we’re still working some things out. The right person will thrive in this environment and relish building out a future-facing finance function. You’ll enjoy problem-solving, feel comfortable handling multiple priorities at once, and seek collaborative solutions. You’ll be adaptable, able to shift focus quickly when things change, and ensure strong communication across the team and with clients to keep everything aligned.

Act as the lead contact for external audits regarding client cash and payment controls. Support the preparation of year end accounts and SCN’s external Audit as it interfaces with Client funds.

• Operational Innovation & Client Service: Proactively research and implement new financial technologies to enhance speed, security and transparency of client services. Continuously evaluate existing workflows to eliminate bottlenecks and improve the client experience. Lead the roll-out of new financial tools or system upgrades, ensuring smooth transition for internal teams and external partners.
• Leadership & Collaboration: Line manage 1–2 members of the finance team, providing mentorship and support. Being the point of escalation for the Finance and Delivery teams on more complex finance queries and dealing directly with our clients for financial solutions.
