Sr. Data Scientist

Target Target · Retail · Bangalore, India

This role focuses on leading the design, development, and productionization of ML systems for e-commerce search, including query understanding, content understanding, retrieval, ranking, and ads/recommendations. It involves owning technical direction, architecting end-to-end solutions, and developing a multi-year vision for search and relevance capabilities. The role requires deep expertise in modern ML techniques, LLM adaptation, and agentic workflows, with a strong emphasis on delivering production ML systems at scale.

What you'd actually do

  1. Leading the design, development, and productionization of ML systems across query understanding, content understanding, retrieval, ranking/relevance, and ads/recommendations
  2. Owning technical direction for a problem area: defining strategy, influencing roadmaps, setting quality bars, and driving execution through a team of scientists and engineers
  3. Architecting end-to-end solutions that integrate modeling, experimentation (offline + online), and engineering systems for scalability, latency, and reliability
  4. Developing a multi-year vision for key search/relevance capabilities on [Target.com](http://Target.com), aligned to business outcomes and measurable metrics
  5. Serving as a technical leader and mentor, raising the bar for scientific rigor, design reviews, and best practices across the org
