A private equity-backed B2B SaaS business operating in a regulated, mission-critical sector is looking to appoint a Financial Controller to strengthen financial control, governance, and reporting as the business continues to scale.

This is a senior, hands-on role suited to a technically strong finance leader who is comfortable owning the detail while also improving processes and building for scale.

The role

The Financial Controller will be responsible for running a robust, scalable finance function, ensuring high-quality reporting, strong controls, and investor-grade outputs. The role spans group reporting, audit, systems, and M&A integration, working closely with senior leadership and external stakeholders.

Key responsibilities include:

Owning the monthly, quarterly, and annual close process, ensuring accuracy, consistency, and timeliness

Preparing and reviewing management accounts, balance sheet reconciliations, and variance analysis

Leading statutory reporting and audit across the group, acting as the primary point of contact for external auditors

Ensuring compliance with UK GAAP and IFRS, including oversight of any international entities

Supporting private equity reporting requirements, including board and investor packs and ad hoc data requests

Maintaining strong financial governance, controls, and documentation aligned to PE and board expectations

Owning and improving core finance systems, data integrity, and reporting processes

Driving automation and process improvements to support scale and efficiency

Managing and developing the accounting team and coordinating with external advisors (audit, tax, payroll, company secretarial)

Leading finance workstreams on acquisitions, including financial assessment, risk identification, and post-acquisition integration of systems, controls, and reporting

Supporting financial due diligence activity as required

Required experience

Qualified accountant (ACA, ACCA, CIMA, or equivalent)

Significant experience in a Financial Controller or senior finance role

Strong technical accounting background (UK GAAP and IFRS)

Experience operating in PE-backed environments

Proven track record in SaaS or recurring revenue, multi-entity businesses

Hands-on experience running financial control, statutory reporting, and audit processes

Comfortable working in a high-growth, change-oriented environment

Desirable experience

HealthTech or similarly regulated B2B SaaS sectors
Experience implementing or scaling finance systems
Exposure to M&A integration in a PE-backed setting

This role will suit someone who combines technical rigour with a practical, delivery-focused mindset, and who enjoys improving how finance functions operate as businesses scale.
