State Street — Bangalore, India

Job Title AVP - Lead Data Scientist (Overall 12+ years of professional experience) Role Description We are seeking an AVP – Lead Data Scientist with deep expertise in applied machine learning and Generative AI/LLM solutions , strong Python skills, and a track record of delivering models and experimentation into production-grade applications/platforms. This role will lead the data science strategy, modeling approach, evaluation standards, and experimentation discipline for GenAI and ML use cases, partnering closely with AI/ML engineers, data engineering, and application/platform teams (including agentic application development). Candidates with experience shaping end-to-end solutions (problem framing → modeling → evaluation → productionization → monitoring) and influencing architecture/design decisions are preferred. Roles & Responsibilities Lead end-to-end data science delivery across multiple initiatives: problem framing, hypothesis design, feature strategy, model development, evaluation, and iteration . Drive development and improvement of ML and GenAI solutions , including model selection, fine-tuning approaches (where applicable), and performance optimization. Define and implement evaluation frameworks for ML/LLM systems (offline metrics, test sets, error taxonomy, regression testing, human evaluation loops). Provide DS leadership for RAG-based solutions (retrieval strategy, grounding, relevance quality, context optimization) and partner with engineering on implementation. Guide data science contributions to agentic applications : tool selection logic, planning/routing heuristics, guardrails, and measurable quality outcomes. Partner with AI/ML engineers and software/platform teams to transition models into production: packaging, APIs, monitoring, and continuous improvement. Collaborate with data engineers to define data requirements, data quality checks, preprocessing utilities, and feature engineering pipelines. Use cloud platforms (Azure preferred / AWS) t
