Responsibilities

Develop AI solutions: Create ML and generative AI systems for RAG pipelines, chatbots, classification, forecasting, and recommendation. Ensure alignment with enterprise standards, seamless integration, and secure scalability.
End-to-End Solution Development: Own the AI lifecycle from problem framing through deployment: data prep, modeling, evaluation, model change management, orchestration, observability, drift detection, and synthetic data generation.
Collaborate closely with AI engineers, data engineers, platform, security, and IT to ensure solutions are robust, maintainable, production ready, follow safety filters/guardrails, and rollback plans.
Prompt and AI Agent design: Experience with system prompts, one-shot, few-shot, and ability to automate or optimize prompts using LLM as a prompt enhancer. Ability to design and orchestrate multi-agent pipelines such as sequential with well-orchestrated callbacks for deterministic AI agent, tool, or LLM behavior.
Project management for AI delivery: Drive execution from discovery to rollout by defining scope, milestones, and acceptance criteria; managing dependencies/risks; coordinating cross-functional workstreams; and maintaining clear status reporting, issue escalation, and delivery timelines.
Stakeholder Collaboration, Domain Knowledge & Influence: Partners closely with Product, Underwriting, Distribution, Risk, Legal, and Compliance to align AI initiatives with enterprise objectives and governance expectations.
Translates complex model behavior and evaluation outcomes into clear, actionable business insights with defined success criteria (accuracy, cost, performance, reuse, ROI).
Develops deep understanding of insurance business processes, data, and regulatory constraints, embedding domain taxonomies, access controls, and security into solution design.
