Senior Expert Acquisition Lead

Team: Human Data

About 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 Senior Expert Acquisition Lead to join our Human Data Operations team, the team responsible for building and scaling the global network of expert contributors that powers our customers' AI training, evaluation, and research.

This isn't traditional recruitment. Rather than hiring employees, you'll design and scale the acquisition strategies, sourcing engines, and systems that enable us to attract, engage, and onboard highly specialised experts across software engineering, healthcare, finance, and other in-demand domains.

This is a high-impact, high-ownership role for someone who enjoys solving complex acquisition challenges. 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.

Working closely with Product, Engineering, Data Science, and the wider Human Data Operations team, you'll help ensure we can rapidly build high-quality expert communities that meet evolving customer demand.

Success isn't measured by how many people you recruit. It's measured by how effectively you build scalable acquisition systems that consistently deliver exceptional experts.

What You’ll Bring to the Role

• 7+ years' experience building acquisition strategies for specialist talent, expert communities, or difficult-to-reach professional audiences.
• Experience working within marketplaces, expert networks, crowdsourcing platforms, talent platforms, or other two-sided ecosystems is highly desirable.
• A proven track record of building scalable sourcing strategies rather than simply executing existing recruitment processes.
• Strong experience sourcing specialist or technical audiences across multiple domains or geographies.
• Experience improving acquisition funnels through experimentation, conversion optimization, and data-driven decision-making.
• Strong analytical skills, with experience using acquisition metrics to evaluate channel performance, funnel health, and growth opportunities.
• Experience building dashboards, reporting, or operational metrics that improve visibility and decision-making.
• 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 ambiguous problems and building processes where none exist.
