The Role
Reporting to the CFO, this role isn’t about routine budgeting and forecasting. You will play a pivotal role in shaping financial strategy and building financial models for long-term strategic projects including M&A and future funding. This is a hands-on role, so you must be excited about rolling up your sleeves and proactive in finding innovative tech-enabled solutions to build efficiencies across the function.
Key Responsibilities:
- Own and maintain the integrated three-statement financial model (P&L, Balance Sheet, Cash Flow), ensuring it is dynamic, accurate, and scalable.
- Lead the annual budgeting and reforecasting processes, partnering with department heads to build bottoms-up plans aligned with strategic goals.
- Deliver rapid, accurate scenario analysis (e.g., hiring ramps, new markets, efficiency initiatives) to support executive decisions and fundraising.
- Act as the custodian of key SaaS metrics (ARR, NRR/GRR, CAC Payback, LTV, Magic Number), ensuring consistent definitions and robust methodology.
- Prepare monthly and quarterly Board and investor reporting, focusing on insights, drivers of performance, and actionable recommendations.
- Benchmark performance against industry peers and best-in-class SaaS standards to identify improvement opportunities.
- Partner with Revenue Operations and leadership to design incentive plans that drive the right behaviours while maintaining capital efficiency.
- Own end-to-end commission and variable compensation calculations, ensuring accuracy, transparency, and timely pay-outs.
- Analyse the ROI of incentive spend to assess whether plans are delivering intended outcomes.
- Lead the transition from manual, Excel-based workflows to more automated FP&A and BI-driven reporting.
- Act as a bridge between Finance and Data teams to ensure CRM and billing systems produce clean, reliable data for reporting.
About you:
- A strong track record in FP&A or Commercial Finance in a high-growth environment.
- Previous experience in a B2B SaaS or relevant subscription business.
- An expert in financial modelling with the ability to build complex and scalable financial models from scratch.
- Experience with financial planning and BI tools would be a strong plus.
- A commercial mind, with a demonstrable ability to identify and focus on the most commercially meaningful and insightful data.
- A storyteller who can extract key insights from complex data sets and communicate these insights in a concise, simple and engaging way to a wide range of stakeholders.
