About the role

• Title of role: Senior Data Scientist
• Location: New York or Boston; Hybrid (2 days in the office required)
• Approved Salary Range: 145k- 150k

About the Role

Rue Gilt Groupe is hiring a Senior Data Scientist to build and ship the personalization systems behind Rue La La, Gilt, and ShopSimon. You will own products end to end, not just the models behind them: from problem framing and success metrics through feature engineering, training, real-time serving, and monitoring, and see your work reach 50M+ members every day.

Flash sale off-price is one of the hardest settings in e-commerce for recommendations. Inventory is limited and short-lived, new products and boutiques launch daily, and cold start is the norm, not the edge case. If that sounds like a fun problem, we would like to talk.

Key Responsibilities

• Personalization at scale: Ranking and recommendation models that power product discovery across boutiques, product pages, and our AI shopping assistant
• Core algorithms: Boutique sort, similar styles, complete the look, and real-time reranking that blends member intent with merchandising goals
• Exploration and learning: Contextual bandits and adaptive strategies that adjust the experience to how each member likes to shop
• Product and model ownership: Shape the roadmap and success metrics with Product, then build the production training and inference pipelines, batch and real-time, with the monitoring and reliability to match
• Experimentation: Design offline evaluation and online A/B tests, and turn results into clear decisions with Product and Merchandising
• GenAI where it helps: Use LLMs and embeddings where they improve recommendations, and expose models as tools the shopping assistant can call
• Cross-functional impact: Partner with engineering, product, marketing, and merchandising teams, and present your work to leadership

Experience and Background Needed

• Contextual bandits, reinforcement learning, or cold-start techniques
• Embeddings, two-tower or sequence models, and vector search
• Databricks (MLflow, Unity Catalog, Model Serving) or GCP (Gemini Enterprise Platform)
• Production LLM for inference, RAG, evaluation, or agent tool calling
• E-commerce, retail, or fashion experience
• Deriving insights from complex data through analysis and modeling

Our Stack

• Databricks, Python, SQL, Spark, PyTorch, GCP (Gemini Enterprise Platform), and AWS.
