Senior Human Data Operations Partner, Research

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.

As a Senior Human Data Operations Partner (Research), you will own the operational success of complex and high‑value research customer projects, while also helping shape the long‑term capability of Prolific’s Research participant supply. This role combines hands‑on delivery with strategic development. You will lead bespoke and technically demanding research engagements – spanning academic studies, product testing, user interviews, and B2B/B2C market research – ensuring feasibility, quality, and execution excellence. Alongside customer ownership, you will identify structural gaps and growth opportunities in our Research supply (i.e. niche professional segments, international expansion) and partner cross‑functionally to build scalable solutions. Success in this role means improving time‑to‑data, fill rates, and customer outcomes – while strengthening the long‑term foundations of Prolific’s Research vertical.

What you’ll be doing in the role:

• Serve as a key resource for client‑specific Research customer teams, acting as the primary point of contact for participant‑related operations.
• Support bespoke client projects by managing participant acquisition, onboarding, verification, and activation processes to meet deliverables.
• Partner with the Head of Human Data Operations to address gaps in participant supply, ensuring alignment with customer requirements and quality standards.
• Develop detailed project plans, workflows, and enablement materials to support efficient delivery.
• Maintain Prolific’s participant pools as high‑quality, diverse, and optimised to meet customer demands.
• Continuously optimise participant onboarding and activation funnels to enhance retention and task performance.
• Monitor participant engagement and quality metrics, using insights to drive improvements.
• Contribute to upskilling programmes and certification processes for participants involved in complex Research tasks.
• Work closely with product, data, science, and customer success teams to align operational priorities with strategic objectives.
• Collaborate with product managers to transform manual processes into scalable, technology‑driven solutions.
• Act as a conduit between delivery teams and operational functions to ensure seamless project execution.
• Document and communicate operational changes to stakeholders across the business, ensuring smooth adoption.
• Develop playbooks and documentation that turn reactive customer requests into repeatable operational capabilities.
• Contribute to roadmap discussions related to Research supply strategy and long‑term vertical growth.

What you’ll bring to the role:

• Experience in operations, ideally in marketplace or platform environments.
• Demonstrated ability to manage multiple projects and meet deadlines in a fast‑paced environment.
• Strong project management skills, with attention to detail and operational execution.
• Experience in implementing and optimising processes to improve efficiency and scalability.
• Proficiency in operational tools and systems such as Metabase, Zapier, Asana, and HubSpot.
• Exceptional communication and documentation skills, with a track record of stakeholder enablement.
• Confidence with data analysis and operational metrics to support decision‑making and continuous improvement.
• Familiarity with human data operations, product or data operations, participant recruitment, or managing global crowdsourcing/gig‑economy platforms.
• Experience supporting AI/ML lifecycle projects, such as data labelling, annotation, or domain‑specific task curation.
• Understanding of Prolific’s platform and its role in delivering high‑quality human data for AI research.
