About the role We are looking for a Senior Data Scientist to be a part of our growing Data Science team, which will report to our Director of Data Science. You will own machine learning that directly shapes what arrives at customers’ front doors. You will iterate on existing models and push our personalization toward more sophisticated approaches as our data grows. Your models will ship, not sit in a notebook. Responsibilities Separate durable preference from noise. Design robust feature representations from high-cardinality, implicit behavioral data (swaps, skips, saves) to capture true user intent and predict future engagement. Model temporal dynamics and changing tastes. Architect sequential and recency-aware systems that adapt to shifting user preferences, ensuring recommendations reflect current intent rather than stale history. Solve the cold-start problem. Leverage cohort signals, clustering, and content embeddings to generalize learnings across users, ensuring that even a new customer’s first box feels deeply personalized. Br
