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 hiring a Data Science Manager, Supply Marketplace to lead this space. This is a high-impact leadership role at the heart of Prolific’s marketplace. You will build and lead the team responsible for the science, models, and decision systems that shape participant marketplace health, from growth and activation to allocation, engagement, quality, and long-term retention.

What you'll be doing

• You will define the strategy for Supply Data Science and lead the analytical and algorithmic foundations that help us understand and optimize participant supply at scale. 
• You will work across participant acquisition, onboarding, liquidity, matching, quality, engagement, and retention, ensuring we can meet rapidly growing demand without degrading participant experience or data integrity.
• You will partner closely with Product, Engineering, Operations, and company leadership to translate complex marketplace problems into a clear roadmap of models, experiments, and decision systems. This includes leading algorithmic work such as matching, ranking, optimization, allocation, and other production-grade systems that improve marketplace efficiency while preserving trust, representation, and participant experience.

What you'll bring 

• This role is well suited to a strong technical lead who is ready to grow into full-time management. Today, this is a small team with room to grow. We are open to someone stepping into their first formal management role, provided they bring strong technical depth, sound judgment, and a track record of leading high-impact work in a product, platform, or marketplace environment.
• You should have experience in experimentation, causal inference, statistical modeling, forecasting, and marketplace or product analytics, ideally in a two-sided marketplace or similar business where supply-demand dynamics, liquidity, and user behavior are central.
• Experience leading algorithmic work such as matching, ranking, optimization, allocation, or decision systems would be especially valuable.
• We’re looking for someone who can set technical direction, partner effectively across Product, Engineering, and Operations, and build a strong team over time.

The job spec is a guideline and we are always looking for the best people—we encourage you to apply even if you feel like you don’t meet all the requirements.
