Senior Expert Acquisition Lead

About this role

Senior Expert Acquisition Lead

Team: Human Data

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.

You'll combine hands-on sourcing with strategic thinking, continuously testing new approaches, improving conversion and building repeatable processes that make expert acquisition faster, smarter and more scalable.

• Confidence working cross-functionally with technical stakeholders, including Product, Engineering and Data Science teams.

• Experience using CRM, sourcing, recruitment or growth tooling, with an eye for automation and process improvement.

• A structured, first-principles approach to solving…
