Primary Responsibilities
Provide technical leadership for a major area of the AI and Data Science portfolio, translating the broader AI strategy and product vision into executable architecture, capability roadmaps, and measurable outcomes
Lead prioritization and technical sequencing of AI products and capabilities within the assigned domain, balancing business value, feasibility, delivery risk, reuse, and long-term platform direction
Hold end-to-end architectural ownership for complex data science and AI capabilities, with accountability for scalability, accuracy, latency, cost, reliability, security, and maintainability in production
Lead the design and production delivery of agentic and LLM-driven systems, including retrieval, tool use, orchestration, state management, evaluation gates, human-in-the-loop controls, and robust failure handling
Define and implement enterprise-grade LLM evaluation and quality programs using automated metrics plus structured human review, covering relevance, faithfulness, hallucinations, robustness, bias, readability, and offline/online evaluation strategy
Establish Responsible AI guardrails for owned capabilities, including prompt-injection defense, toxicity and safety filtering, privacy/PII controls, scope and refusal behavior, adversarial testing, automation-bias mitigation, auditability, and alignment with RAI/AIRB processes
Lead end-to-end MLOps and LLMOps design, including reproducible experimentation, model and prompt lifecycle management, CI/CD, release controls, monitoring, drift detection, observability, rollback, data pipelines, orchestration, and technical documentation
