Marketing Manager, Participants

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

Prolific\’s 200,000+ verified participants across 40+ countries are our competitive moat. Far more than a supply pool, our participants are a community of engaged contributors who make high-quality human data possible for AI labs, researchers, and enterprises.

What you’ll be doing in the role

• Design and run participant engagement programs that drive loyalty and retention, including seasonal campaigns, challenges, prize draws, recognition initiatives, ambassador programs, and advisory boards
• Own participant-facing content and education, producing newsletters, platform updates, training programs, webinars, case studies, and user-generated content in collaboration with internal and external experts
• Build and evolve the participant brand and value proposition, clearly communicating the tangible and intangible benefits of participating on Prolific across global and specialist segments
• Lead participant trust and transparency communications, including messaging around data quality standards, verification processes, policy changes, and product updates to drive adoption and confidence
• Be deeply embedded in participant communities, engaging across channels such as Reddit, Discord, forums, and review platforms, monitoring sentiment, moderating discussions, and responding quickly to concerns
• Bring the participant voice into Prolific, designing feedback loops, conducting participant research, and advocating for participant needs in product, supply, and strategic decision‑making
• Monitor market and competitor trends to ensure Prolific remains the best‑in‑class platform for online research participation and AI training

What you’ll bring to the role

• 5+ years in community management, product marketing in a B2C or marketplace environment
• Track record of building authentic relationships at scale, not just transactional marketing
• Experience creating and running engagement programs that drive measurable behavior change
• Content creation skills – you can write newsletters, develop messaging, create educational content
• Comfortable working in high‑growth, high‑autonomy environments and building programs from scratch
• Experience working with global, distributed communities
