About the role

Key responsibilities & impact

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.

Requirements

What you’ll need

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.
