Chief Financial Officer | Post-Series B2B SaaS | Fully Remote

Chief Financial Officer | Post-Series A B2B SaaS | Fully Remote (UK)

We are partnering with a growing, post-Series A B2B SaaS business operating in a specialist enterprise software category. The platform provides mission-critical solutions to organisations with complex operational and regulatory requirements.

The company is revenue-generating, capital-efficient and backed by institutional investors. With a distributed team across multiple geographies and a strong recurring revenue base, the business is entering its next phase of structured growth.

As part of this evolution, they are seeking an experienced Chief Financial Officer to act as a strategic partner to the Founder & CEO. This role will play a central part in strengthening financial strategy, enhancing investor communication, and building governance frameworks appropriate for a scaling, multi-entity SaaS organisation.

Reporting directly to the CEO, the CFO will take full ownership of financial operations and reporting, ensuring clarity, insight and forward-looking strategic control.

This is a hands‑on role suited to a finance leader who thrives in a lean environment and is comfortable operating as a player‑coach. The successful candidate will combine strong financial controls with commercial depth, elevate the sophistication of SaaS metrics and modelling, and build a scalable finance function fit for the next stage of growth.

The CFO will play a central role in investor communications and board engagement, strengthening financial storytelling and supporting future fundraising initiatives.

• Own cash forecasting, financial modelling and unit economics analysis to drive profitability and growth insight.
• Partner closely with the CEO on investor communications, fundraising and board reporting.
• Implement automation, reporting enhancements and scalable processes to modernise the finance function.
• Elevate SaaS KPI tracking to ensure finance acts as a true front‑office contributor to revenue growth.
• Mentor and develop the finance function as the business scales.
• Establish governance frameworks appropriate for a multi‑jurisdictional SaaS organisation.

• Proven hands‑on experience managing multi‑entity operations and cross‑border considerations.

• Experience implementing reporting improvements, automation or data visualisation tools.
• Strong commercial judgement and intellectual agility.
• Comfortable operating as a player‑coach in a lean, scaling environment.

• Experience operating within a VC‑backed environment, ideally through fundraising rounds from Seed to Series A/B.
• Exposure to long sales cycles and complex enterprise deal structures (multi‑year contracts, phased implementations, revenue recognition considerations).
• Experience building or reshaping a finance function from a lean starting point ahead of scale.
• Strong understanding of core SaaS metrics (ARR, NRR, CAC, LTV, cohort analysis) and their application in strategic decision‑making.
