Head of FP&A

Prolific

Prolific is not just another player in the AI space – we are the architects of the human data infrastructure that's reshaping the landscape of AI development. In a world where foundational AI technologies are increasingly commoditized, it's the quality and diversity of human-generated data that truly differentiates products and models.

The role

We’re looking for a strategic and commercially minded finance leader to build and scale our FP&A capability during a critical phase of growth. This role sits at the center of company decision-making, partnering closely with the CFO and leadership team to drive financial planning, business performance, strategic insight and operational excellence across the organization. You’ll own the company’s financial planning and reporting cadence, including board reporting, executive leadership updates, and company-wide financial performance reporting, ensuring stakeholders have clear, actionable insight to support decision-making at every level.

You’ll be responsible for developing a best-in-class FP&A function that combines robust financial modeling, scalable systems, deep commercial analysis, and high-quality decision support. This role requires a proactive leader who not only delivers insight but also actively shapes business strategy by identifying opportunities, making recommendations for change, and influencing key commercial and operational decisions.

A key focus of the role will be simplifying complexity across planning, forecasting, and performance management within a fast-paced, high-growth environment. You’ll bring structure, clarity, and scalable processes to support rapid business expansion while enabling faster and more effective decision-making across the company. You’ll also lead the evolution of our financial systems and infrastructure, including the implementation of next-generation FP&A and financial platforms, while embedding AI and automation into core finance workflows and processes to improve efficiency, insight generation, and forecasting capability. 

Alongside this, you’ll build, mentor, and elevate a high-performing FP&A team that acts as a true strategic partner to the business — fostering a culture of commercial thinking, innovation, accountability, and continuous improvement. This is an ideal opportunity for someone who thrives in fast-paced, high-growth environments, enjoys solving complex commercial problems, embraces technology and AI-driven transformation, and has the confidence to lead strategic conversations and influence organisational direction.
