Controller

Our client is a fast-growing, venture-backed SaaS company in the AI space, serving a large, global customer base. The business is fully remote with a distributed, global team.

The Role

We're looking for a hands-on Controller who owns the numbers end to end — someone who does the work personally rather than just reviewing it. You'll partner directly with company leadership and the wider finance function, bringing enterprise-grade financial discipline to a business that runs at a scale well beyond its headcount. With high transaction volumes, a subscription-based revenue model, and a lean finance team, the role demands both precision and pace. You'll begin as an individual contributor and grow the accounting function as the company scales.

Key Responsibilities

• Own the monthly close process and management reporting in full — financial statements, recurring revenue metrics by product/plan, gross margin analysis, expense classification, and cost capitalization, all in accordance with US GAAP.

• Oversee billing and revenue integrity — reconcile payment processor data against internal reporting systems, track refunds/credits/disputes and bad debt, monitor processing fees, and manage recovery workflows for failed payments.

• Administer global payroll and contractor payments — run payroll for employees and international contractors across multiple platforms and currencies, and maintain the headcount and compensation records.

• Manage accounts payable and vendor relationships — invoice review and approval workflows, vendor disbursements, and company-wide spend visibility.

• Lead cash and treasury management — monitor balances across banking relationships, ensure payroll and large payments are properly funded, and maintain disciplined treasury processes.

• Support audit and diligence readiness — partner with top-tier external auditors and advisors on annual audits, diligence requests, and tax matters, keeping the books audit-ready at all times.

• Produce the recurring business reporting that leadership relies on — recurring revenue, churn, upsell, and team performance metrics.

• Own net revenue retention (NRR) reporting and cohort-level analysis of retention, expansion, and churn by product, plan, and customer segment.

• Own and evolve the finance systems stack — select and implement scalable accounting, billing, and banking tools, and drive automation wherever possible.

What You'll Bring

• Prior experience as a Controller or senior accounting leader at a large-scale, product-led-growth SaaS company with a self-serve, high-transaction-volume business model.

• Deep, hands-on experience with high-volume subscription billing systems.

• A recognized professional accounting qualification (CPA, ACA, ACCA, or equivalent).

• Strong fluency in US GAAP.

• A true hands-on operator, comfortable owning the close solo before building out a team.

• Based in the UK or Canada.

Nice to Have

• Experience taking a company through a Big 4-caliber audit.

• Experience with usage- or credits-based pricing models.

• Experience preparing a company for a financing round, M&A process, or IPO-level reporting standards.

• Experience at a fast-growing, remote-first company.
