Job description

Senior Data Scientist - Growth

Prolific is not just another player in the AI space we are the architects of the human data infrastructure thats reshaping the landscape of AI a world where foundational AI technologies are increasingly commoditised its the quality and diversity of human-generated data that truly differentiates products and models.

The Role

We're looking for a Data Scientist with strong analytical skills and a passion for solving complex systems problems to join our team. You will own the end-to-end growth funnel for our core participant pool treating it as a dynamic growth engine. You'll work cross-functionally with product engineering and marketing teams driving initiatives that attract activate and retain high-quality participants at scale. You'll have significant autonomy to design build and deploy models, develop measurement frameworks and influence decisions that directly impact our platforms growth trajectory and business strategy.

What you'll be doing

• Develop and own the quantitative framework that measures and optimizes the entire participant growth funnel (Acquisition Activation Retention Referral) creating the core metrics and models that guide our growth strategy.
• Develop sophisticated models to understand user acquisition channels predict participant lifetime value (LTV) and identify the key drivers of engagement and churn.
• Analyze and optimize the levers of growth including referral programs onboarding flows and communication strategies to build a healthy engaged participant base.
• Collaborate closely with product managers engineers and marketing partners to identify opportunities where data science can drive the strategy for participant acquisition and long‑term retention.
• Synthesize complex analyses of our growth funnels and user journeys into actionable insights presenting compelling data‑driven narratives to influence strategic decisions.
• Design and analyze experiments to test hypotheses about user acquisition channels onboarding experiences and retention tactics.
• Partner with data engineers to enhance data pipelines and logging systems creating a robust foundation for advanced growth modeling and user behavior analysis.

What you'll bring

• Experience in modeling and analyzing user growth funnels such as acquisition loops user lifecycle marketing or product‑led growth dynamics.
• A strong background in building measurement systems and analytical frameworks particularly using experimental design and advanced causal inference methods.
• Experience with or interest in working with human behavioral data annotation / labeling systems or projects involving human feedback for AI development and evaluation.
• Solid software engineering fundamentals with expertise in Python / R SQL AI / ML frameworks and the modern data science stack.
• A toolkit spanning from classical statistical methods to state‑of‑the‑art ML techniques (especially in predictive LTV churn modeling and marketing mix modeling) with knowledge of how to choose and apply the right tool for each unique problem.
• Proven ability to effectively communicate with and influence stakeholders across the organization from engineers to executives.
• Ability to thrive in fast‑paced environments and balance speed with quality.
• Strong prioritization skills consistently focusing on high‑impact work.
