Team: Reporting to the CEO About the Role We're a 30-person company scaling rapidly with a usage-based revenue model. We need someone to own finance end-to-end. You will be taking ownership of a function from the ground up - we have reached a scale where we need strong stewardship of this critical function. You'll be the person who makes sure the numbers are clean, the forecasts are credible, and the leadership team has the financial clarity to make good decisions fast. You'll work closely with the leadership team, not in a back office. We have existing accounting infrastructure in place, but it needs a proper owner who can run the day-to-day while also thinking strategically about how we scale. What You'll Do Accounting & Financial Control Own management accounts, month-end close, and financial reporting. Manage AP and AR Ensure tax compliance across USA, UK and Ireland Own relationships with external accountants and auditors FP&A & Budgeting Build and own the company budget with regular reforecasting Develop financial models and scenario analysis to support strategic decisions Track and report on SaaS and usage-based metrics: ARR, NRR, gross margin, CAC, LTV, revenue per transaction Prepare board packs and investor reporting Strategic Finance Support the leadership team on resource allocation, hiring plans, and go-to-market investment Support fundraising preparation when the time comes Provide commercial analysis on pricing, customer economics, and unit economics Operations Manage payroll coordination across USA, UK and Ireland Handle procurement and vendor management Jump in wherever else you are needed!
