Sales Executive jobs in United Kingdom

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.

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.

• 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

• 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

We've built a unique platform that connects researchers and companies with a global pool of participants, enabling the collection of high-quality, ethically sourced human behavioral data and feedback. This data is the cornerstone of developing more accurate, nuanced, and aligned AI systems.

We believe that the next leap in AI capabilities won't come solely from scaling existing models but from integrating diverse human perspectives and behaviors into AI development. By providing this crucial human data infrastructure, Prolific is positioning itself at the forefront of the next wave of AI innovation—one that reflects the breadth and the best of humanity.

Working for us will place you at the forefront of AI innovation, providing access to our unique human data platform and opportunities for groundbreaking research. Join us to enjoy a competitive salary, benefits, and remote working within our impactful, mission-driven culture.
