The job Join our Value Creation stream as a Senior Product Analyst embedded in Core Health teams. You will focus on deepening user engagement and driving meaningful product outcomes through personalised experiences, content relevance, gamification mechanics, new market and segment expansion, and AI-powered personalisation.

You'll be responsible for: Working closely with Product Managers, UX Researchers, Designers, and Engineers to support data-driven decision-making across core product initiatives — from feature conception through to post-launch evaluation. Identifying new growth opportunities across underserved user segments, behavioural patterns, and emerging use cases that can be addressed through core product development. Helping the team understand which company-level goals can be influenced through product and experimentation decisions, defining relevant proxy metrics, and monitoring them over time.

Supporting hypothesis formulation and prioritisation using data: estimating segment sizes, potential impact, and expected uplift across personalisation, gamification, and content initiatives, while defining clear success metrics grounded in user behaviour. Helping the team prioritise ideas and initiatives based on expected impact, confidence level, and effort — with particular attention to long-term retention and engagement signals, not just short-term conversion. Participating in product planning and roadmap discussions, providing analytical input to shape priorities around core product bets — including new segments, market expansion, AI-driven features, and engagement mechanics.

Evaluating experiment results holistically, assessing the true impact on core product and business metrics rather than isolated local effects — including downstream effects on retention, lifetime value, and user satisfaction. Translating analytical findings into clear, actionable recommendations for the team and stakeholders, helping bridge the gap between data signals and product strategy. Your Experience Must have: At least 5+ years of work experience as a Data/ Product Analyst; Experience with A/B testing, knowledge of statistics for A/B testing; Advanced SQL/Python / R for data analysis; Experience in data visualization in Python/ Looker /Tableau or similar.
