Participant Marketing Manager

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. We're looking for someone to own our marketing around the participant experience, building the trust, connection, and engagement that keeps our community thriving and positions Prolific as the platform of choice for quality-conscious contributors. This is a new role in the Marketing function, aligned to our Supply business unit. You'll work closely with Marketing, Growth, Product, and Ops teams to ensure participants feel heard, valued, and informed — which directly impacts data quality, retention, and Prolific's reputation in the market.
