Responsibilities
Design LTV models that capture structural—not just seasonal—value
Separate long-term signal from short-term promotions and seasonality
Model retention and monetization dynamics that persist across cycles
Stress-test models across cohorts launched in different macro and regulatory regimes
Incorporate high-granularity features
Build user- and cohort-level models that account for:
Geography (e.g., zip code, DMA, state-level effects)
Regulatory or market-specific constraints
Behavioral and product-usage signals
Explicitly model heterogeneity rather than relying on global averages
Ensure durability and generalization
Validate models across multiple years, product launches, and seasonal cycles
Monitor stability, drift, and cohort aging effects
Revisit assumptions as the business and user base evolve
Make LTV actionable at different resolutions (user, cohort, geo, channel)
Partner with Growth to avoid overfitting CAC decisions to short-term spikes
Align with Finance on long-range forecasting assumptions
Push back against simplistic or purely seasonal interpretations of value
Clearly communicate uncertainty, confidence intervals, and limitations
Prevent misuse of early-cohort or promotion-inflated signals
Qualification
Required
5–8+ years of experience as a Data Scientist in a consumer marketplace with meaningful seasonality
Proven ownership of an LTV model that lived in production for multiple years
Proven ownership of an LTV model that survived multiple seasonal cycles
Proven ownership of an LTV model that informed real budget, growth, or product decisions
Deep experience with cohort-based modeling and survival analysis
Deep experience with feature-rich segmentation (geo, behavior, product mix)
Deep experience with de-biasing early lifecycle and promotion-heavy data
Strong SQL and Python (or R); comfortable working with large-scale feature pipelines
Demonstrated ability to explain why a model generalizes—not just that it performs
