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.

You'll also be expected to get your work in front of the right audiences at conferences, journals, in the press, and through Prolific's own channels. This isn't a role for someone who needs a well-worn path. We want someone who generates more ideas than they can execute, moves quickly, and thrives when the next interesting problem is always around the corner.

- Presenting and disseminating your work: Representing Prolific at academic conferences and industry events, and working with our marketing team to maximise the reach and impact of research findings
- Contributing to the wider sciences agenda: Our current work spans data quality, representativeness, synthetic data, and methodological innovation. We're looking for someone who can help shape this agenda, not just execute within it
Who we're looking for
Core requirements:
- PhD in a relevant quantitative field such as psychology, research methodology, computational social science, statistics, economics, social science, or similar
- Strong grounding in online research methods, with experience in at least some of: online sampling methodologies, data quality assessment, non-probability sampling, or synthetic data approaches
- Demonstrated ability to lead research projects end-to-end, with a track record of publications, conference presentations, or equivalent public outputs
- Strong quantitative research skills, including experimental design, statistical analysis, and data interpretation, with proficiency in tools such as R, Python, or Qualtrics
- A self-starter who is comfortable executing a research programme with limited hand-holding and genuine intellectual curiosity about where online research is heading
- High output and comfortable working at pace, you get things done, ship work, and don't wait for perfect conditions
- An ideas-first mentality: you keep a close eye on the latest developments across relevant fields, and you're quick to spot their implications for online research and translate them into concrete directions
- Based in the US East Coast or UK
Nice to have:
- Postdoctoral or industry research experience (one or the other is expected if industry experience is limited)
- Familiarity with online panel platforms and the trade-offs of working with them
- Experience working across academic–industry partnerships
- Comfort with on-the-record commentary or media engagement
Why Prolific is a great place to work

- Analytics Expertise: Advanced SQL and strong Python proficiency (e.g. pandas, experimentation analysis, automation), with a track record of building scalable reporting frameworks in modern BI tools (Metabase, Looker, Tableau). Comfortable owning problems end-to-end — from raw data to executive-ready insight.
- Experimentation & Statistics: Experience designing and analysing A/B or operational experiments, with solid grounding in statistical concepts and causal thinking.
- Commercial Acumen: Strong ability to connect operational metrics to revenue, margin, and financial performance — understanding not just what is happening, but why it matters commercially.
- Autonomy & Ownership: Comfortable operating with high autonomy in a fast-moving environment, setting priorities, challenging assumptions, and driving initiatives from problem definition through implementation.
- Stakeholder Management: Proven ability to partner across Product, Operations, Commercial, and Finance functions.
- Marketplace Understanding: Strong grasp of B2B and two-sided marketplace metrics and economics.
- Clear Communication: Ability to translate complex analysis into concise, decision-ready insights that shape strategy and execution.

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
Prolific for AI is a high-growth, greenfield vertical building the infrastructure behind human-aligned AI. As Data Science Manager, you'll build and lead the data science and analytics function for this vertical - setting strategy, hiring the team, and partnering with commercial, product, and ops stakeholders to drive measurable impact. You'll define what great looks like, then build the team and systems to deliver it.
What you'll be doing
Build & Lead the Team
- Hire, develop, and retain a high-performing team of Data Scientists and Analysts
- Set clear expectations for technical quality — rigorous causal inference, well-designed experiments, principled modelling — and coach the team to meet them
- Define ways of working, prioritisation, and how the team interfaces with commercial and product stakeholders
Drive Commercial Growth through Data
- Ensure your team delivers analytics that fuel the Prolific for AI Sales and Ops functions: pipeline health, forecasting, customer health, and retention signals
- Act as a senior data thought partner to commercial leadership — translating business questions into analytical problems and outcomes into decisions
Own the Experimentation Standard
- Set and hold the bar for how your team designs, runs, and interprets experiments — going beyond basic A/B testing toward rigorous causal inference and algorithmic work
- Partner with Product to make experimentation a core capability across the vertical, not just a tool
Ensure Data Quality at Scale
- Lead your team to build scalable frameworks that guarantee high-quality AI training and evaluation data for Prolific's frontier lab partners
- Establish governance: clear rules, repeatable checks, and shared standards that Product and Engineering can build against
- Be hands-on in the early phase — contributing technically where needed — then transition to technical oversight and mentorship as the team matures
What you'll bring
- Proven track record leading data science or analytics teams — you've hired, developed, and held a high technical bar
- Technically deep enough to set direction, review work critically, and earn credibility with strong ICs — not just manage process
- Expertise in experimentation and causal inference; you know the difference between a well-designed study and a convincing-looking one
- Ability to translate ambiguous, high-stakes business problems into structured analytical work
- Strong stakeholder influence — you can align Product, Eng, Ops, and Commercial without direct authority
- Bonus: experience with AI data pipelines, RLHF, or human-in-the-loop evaluation systems
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.
