The Lead Data Scientist will identify AI opportunities tied to Institutional and Specialty business challenges, drive experimentation and delivery of digital data science and AI product innovations, and partner with internal stakeholders to translate business strategy and voice of customer into technical plans, build decisions, and lifecycle directions.

Key Responsibilities

Identify and define opportunities aligned to Institutional and Specialty business challenges, navigating a range of problem types and solution approaches.
Drive experimentation and delivery of digital data science and AI product innovations aligned with the digital product vision.
Partner with internal business stakeholders to translate business strategy and VOC into technical opportunities, builds, and lifecycle decisions, communicating clearly across levels.
Architect and build AI solutions end to end across classical ML, LLM-based applications, and multi-agent systems, owning technical design decisions from the data layer through inference, API exposure, and product integration.
Own the production lifecycle of AI agents and models, including QA, monitoring, drift detection, prompt and version management, and retraining pipelines for reliable customer-facing outcomes.
Define and track effectiveness metrics for AI features in partnership with product and commercial teams.
Design evaluation frameworks with responsible AI practices, including champion/challenger pipelines, automated regression testing, guardrails, and audit logging.

1 year of shipping production LLM applications, including prompt engineering as a real discipline (structured prompts, output schemas, exclusion rules), RAG over vector indexes, and combining GenAI reasoning with deterministic logic for reliable and auditable outputs.
Hands-on experience building and orchestrating multi-agent systems, including sequential handoffs, tool-calling, and scheduled or DAG-based workflows, with judgment on when to use probabilistic reasoning versus deterministic rules.
Proven experience building and operating evaluation and quality frameworks for GenAI output, including measuring improvements from prompt or model changes, calibrating against subject-matter-expert ground truth, and reducing hallucinations in customer-facing products.
Experience with being a people manager.
Proven ability to balance business needs with technical rigor and communicate approach, assumptions, and tradeoffs to technical and non-technical audiences.
Excellent communication and presentation skills, including translating technical work into business context with structured, concise findings for diverse stakeholders.
