Senior Data Scientist (Retention & Product)

• We’re hiring an ML-focused Data Scientist to own retention and churn for CookUnity. In a weekly subscription business, retention is the engine of growth — the gap between a healthy customer and a churned one is often just a few weeks of activity
• Your job is to predict who’s at risk, understand why they leave, and power the interventions that keep customers ordering and win back the ones who go. This is a hands-on role embedded with Product, CRM, Marketing, and Engineering
• Churn & retention modeling: Build churn/survival models and lifecycle-state models that flag at-risk customers early and anticipate where each customer is heading
• Intervention & reason understanding: Power the retention interventions that act on that risk — save flows, skip/pause deflection, lifecycle messaging — and classify why customers churn so the response fits the reason rather than being generic
• Resurrection & win-back: Develop propensity models and personalized experiences that bring churned customers back
• Personalization & Next-Best-Action: Decide the right action, offer, and message per customer across product surfaces, with an uplift layer measuring incremental impact
• Offer & promo optimization: Determine who gets an incentive, when, and at what value — maximizing retained revenue without over-discounting
• Production & MLOps: Own the full model lifecycle and ship models into the systems where they act; handle monitoring, retraining, and drift
• Experimentation & incrementality: Design experiments and uplift measurement so we intervene on movable customers and not on those who’d retain anyway

• End-to-end ML & MLOps: building, validating, and deploying models in production (CI/CD, registries, containerization, orchestration, monitoring)
• 5-8+ years in data science, applied ML, or statistics, shipping production models
• Collaboration: excellent communication; able to embed with Product/CRM/Marketing and turn models into decisions
• Ability to leverage generative AI to increase output quality and speed
• Engineering & tooling: strong Python (pandas, scikit-learn, gradient boosting; deep learning a plus), SQL, code hygiene and reproducibility
• Retention/churn depth: churn prediction, survival / time-to-event modeling, and lifecycle-state models in a subscription or recurring-revenue context
• Education: BS in a quantitative field required; MS/PhD preferred
• Causal & experimentation rigor: uplift/incrementality measurement and A/B testing, with the judgment to separate true impact from selection effects
• Lifecycle-state / Hidden Markov models for churn
• Causal and uplift libraries (e.g. EconML) or survival-modeling packages
• Subscription marketplaces, food-tech, or consumer marketplaces with a retention mandate
• Recommenders, embeddings, or personalization for retention and win-back
