Finance Manager Series B Clinical AI Scale-Up | London / Hybrid

The Client

Harmonic is delighted to be partnering with a Series B clinical AI company that is redefining how healthcare is delivered at scale. Backed by a premier Silicon Valley venture fund and holding the only Class II medical device certification for AI-enabled diagnostic support in their category, this business has built a genuinely world-class product, validated in peer-reviewed research and deployed across hundreds of thousands of patients. With a strong UK footprint and revenue accelerating rapidly in the US, they are now entering a new phase of international complexity and need a Finance Manager to grow with them.

The Role

Reporting to the Group Finance Director, the Finance Manager will own the core financial operations of a business scaling fast across two continents. The immediate priorities are US entity consolidation, an ERP migration away from Xero, and ensuring revenue recognition is robust as the business moves from a B2B-only model into direct-to-consumer channels in the US. Beyond those, you will own management accounts, month-end close, payroll, tax credits, and reporting against a debt facility. You will also support financial modelling and cash forecasting and will play a hands-on role in preparing the business for its next funding round. This is a genuinely broad role for someone who wants real responsibility in a high-growth environment, not a narrow specialism.

Key Responsibilities

• Own month-end close and prepare management accounts across multiple group entities.
• Lead consolidation of US entities as the American business scales, ensuring accuracy and timeliness across the group.
• Project-manage the migration from Xero to a new enterprise ERP, owning the transition end to end.
• Manage revenue recognition under IFRS 15 and US GAAP, covering SaaS contracts, healthcare agreements, and US insurer models as the business expands into direct-to-consumer.
• Run payroll and support on UK and US tax credit processes.
• Manage reporting obligations to the company's debt provider.
• Support the Group Finance Director with financial modelling, cash forecasting, and investor reporting ahead of a Series C raise.
• Leverage AI tools actively in finance workflows; the business expects proficiency well beyond basic use.

Essential Experience

• Qualified accountant (ACA, ACCA, CIMA, CPA, or equivalent); part-qualified considered where hands-on experience is strong.
• Circa 5 years of experience in finance or accounting roles, with meaningful exposure to international operations.
• Proven, hands-on experience managing US entity consolidations.
• Experience owning or leading an ERP migration (specifically moving away from Xero, or comparable transition).
• Strong technical understanding of revenue recognition under IFRS 15 and/or US GAAP.
• Background in a scaling startup environment, ideally with Series A, B, or C experience.

Desirable Experience

• CPA qualification or significant US tax and compliance exposure.
• Experience with debt facility or structured finance reporting.
• Financial modelling and rolling cash flow forecasting.
• Comfort building or working alongside AI tooling in a finance context.
