[Remote] Senior Data Scientist, Retention & Product
Note: The job is a remote job and is open to candidates in USA. CookUnity is a pioneering platform that connects the world with exceptional chefs and delivers millions of meals annually. They are seeking a Senior Data Scientist focused on retention and churn, responsible for developing models to predict customer behavior and implementing strategies to enhance customer retention in a subscription business.
Responsibilities
- 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
Skills
- 5-8+ years in data science, applied ML, or statistics, shipping production models
- Retention/churn depth: churn prediction, survival / time-to-event modeling, and lifecycle-state models in a subscription or recurring-revenue context
- Causal & experimentation rigor: uplift/incrementality measurement and A/B testing, with the judgment to separate true impact from selection effects
- End-to-end ML & MLOps: building, validating, and deploying models in production (CI/CD, registries, containerization, orchestration, monitoring)
- Engineering & tooling: strong Python (pandas, scikit-learn, gradient boosting; deep learning a plus), SQL, code hygiene and reproducibility
- Collaboration: excellent communication; able to embed with Product/CRM/Marketing and turn models into decisions
- Education: BS in a quantitative field required; MS/PhD preferred
- Ability to leverage generative AI to increase output quality and speed
- Subscription marketplaces, food-tech, or consumer marketplaces with a retention mandate
- Lifecycle-state / Hidden Markov models for churn
- Causal and uplift libraries (e.g. EconML) or survival-modeling packages
- Recommenders, embeddings, or personalization for retention and win-back
