About the Role
We're a venture-backed health-tech business on a mission to help people take control of their health, with strong growth behind us and big plans ahead. As we build out our finance function, we're looking for someone sharp, organised, and brilliant with systems to run the operational engine of our finance team. Reporting to the Finance Lead, you'll own the day-to-day running of finance and support decision-making across the business. You'll work closely with our B2B team, a fast-growing side of the business with big expectations ahead. We care far more about how you think than which exams you've passed. If you're a natural problem-solver who spots what isn't working and fixes it, who's ruthless about accuracy, and who loves making a process better, we'll teach you the accounting. This is a role you can grow into and, over time, well beyond. We're a small team that supports each other, but we also need someone who can work independently and take the initiative. You'll have real ownership of your work, with the freedom to improve how things are done, broad exposure across the business, and room to grow, all while doing genuinely meaningful work.

Responsibilities
Run the day-to-day finance function, keeping things accurate, timely, and well-controlled. Own the month-end close and monthly management accounts, including balance sheet reconciliations and revenue recognition. Deliver monthly reporting and commercial analysis, including variance analysis and ad hoc deep-dives, to present performance and insight clearly. Act as finance business partner to the B2B team and ops leads, supporting their finance needs, ensuring on-time payment and no revenue leakage, with revenue reporting at the contract level. Support the budgeting, forecasting, and FP&A cycle, partnering with the Finance Lead on planning and decisions. Manage the annual audit, acting as the main point of contact for auditors and ensuring a smooth close. Design, build, and improve the processes, systems, and controls the finance function needs as the business scales. Work across teams to provide insight, drive efficiency, and support decision-making.
