Senior Data Scientist

Build the Data & Intelligence Layer for a Next-Generation MarketplaceNearly $1 trillion is spent globally each year on talent acquisition, yet the process remains inefficient, fragmented, and highly manual.Our client is building a category-defining marketplace platform that combines human expertise, proprietary data, and AI-driven workflows to transform how critical business outcomes are delivered. Every interaction on the platform generates unique behavioural, transactional, and operational data, creating a rich environment for experimentation, optimisation, and machine learning.As the platform scales, data science sits at the centre of product strategy, marketplace health, growth, and intelligent automation.The OpportunityWe're looking for a Senior Data Scientist to take ownership of high-impact initiatives across growth, marketplace dynamics, product optimisation, incentives, and AI-powered decision systems.This is an opportunity to work on the types of problems typically found in leading marketplace businesses, including:Matching and recommendation systemsSupply and demand optimisationMarketplace liquidity and efficiencyPricing and incentive designGrowth experimentationUser activation and retentionPredictive modelling and decision intelligenceYou'll partner closely with Product, Engineering, Design, and Commercial teams to identify opportunities, design experiments, build models, and influence product direction through data.What You'll Be DoingGrowth & ExperimentationDefine and optimise key funnel metrics across acquisition, activation, retention, and monetisationDesign and analyse experiments to improve user behaviour and business outcomesDevelop predictive models that drive growth and engagementMarketplace & Product IntelligenceImprove matching quality, marketplace efficiency, and workflow performance through analytics and machine learningBuild measurement frameworks for marketplace health and operational performanceDevelop decision systems that improve outcomes for all participants on the platformIncentives, Pricing & BehaviourDesign and evaluate incentive structuresModel behavioural responses to pricing and marketplace changesForecast impact and identify unintended consequences or gaming risksDevelop guardrails that support sustainable marketplace growthApplied Machine LearningBuild, deploy, and monitor production-grade modelsPartner with engineering teams to operationalise ML solutionsContribute to the evolution of AI-assisted and autonomous workflows across the platformWhat We're Looking ForProduct-Oriented Data ScientistYou focus on business outcomes, not just analysis.
