Data Analyst (Supply)

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

As Prolific scales, maintaining a healthy and sustainable participant marketplace is critical to meeting the growing demand for high-quality human data. To champion this effort, you will own analytics across the entire participant lifecycle, spanning acquisition, onboarding, activation, engagement, quality, retention, and reactivation.

Working hands-on with SQL and Python, you will build the metrics, dashboards, and experimentation frameworks that help us understand behavior and improve the participant experience. By partnering closely with Product, Operations, Growth, and Data Science, you will identify opportunities, structure experiments, and translate complex marketplace data into clear decisions that ensure participant health, marketplace liquidity, and long-term supply sustainability.

What you’ll bring to the role

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.
Lifecycle Analytics: Experience analysing user acquisition, onboarding, activation, engagement, retention, churn, and behavioural cohorts.
Experimentation & Statistics: Experience designing and analysing A/B or operational experiments, with solid grounding in statistical concepts and causal thinking.
Product Thinking: Ability to translate participant and marketplace challenges into measurable hypotheses, success metrics, and actionable recommendations.
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.
