Interim Finance Director/FP&A Lead

Interim Finance Director/FP&A Lead (FTC or Day Rate) £120-£130k equivalent

PE-backed SaaS business | London (Hybrid) | ASAP start (two weeks notice max)

We are supporting a PE-backed SaaS business with the appointment of an Interim Senior FP&A Lead / Finance Director to provide cover during a senior leadership maternity leave.

This is a 6–7 month assignment, starting in late February or early March, with potential to extend to c.9 months. The role can be structured as a fixed-term contract or day-rate interim, depending on candidate preference.

This is not a statutory Finance Director role. The emphasis is firmly on FP&A, commercial planning and performance management within a fast-growing, sponsor-backed environment.

The Role

You will take ownership of the group’s financial planning and forecasting agenda, operating as a senior number two to the CFO and working closely with the wider leadership team.

Key responsibilities include:

• Leading the full reforecast and annual budgeting cycles, including scenario planning and consolidation across multiple product lines
• Owning the production of budget and reforecast outputs for board and investor review
• Maintaining a strong audit trail, version control and sign-off across all financial models and decks
• Acting as a senior commercial partner to revenue, customer operations and go-to-market teams
• Reviewing and challenging new product and investment business cases
• Providing guidance and oversight to an established FP&A resource
• Ensuring continuity and quality across monthly performance processes

The role is delivery-focused and requires someone able to grip quickly, operate with pace, and add judgement rather than simply process.

What We’re Looking For:

• Proven experience in a senior FP&A or FP&A Director roles
• Background in PE-backed, SaaS or recurring-revenue businesses is essential
• Comfortable operating in scale-up environments with tight planning timelines
• Strong stakeholder management skills and commercial judgement
• Able to review, steer and consolidate complex financial outputs rather than build everything personally
• Immediately available or short notice preferred (2 weeks max)

Logistics:

• Start: Mid Feb
• Location: London, hybrid working (2–3 days in office)
• Contract: FTC or day-rate interim

This is a high-impact interim role in a well-capitalised business with a strong finance platform already in place.
