The Senior AI Engineer designs and operates production AI systems integrated with core platforms including agent workflows retrieval strategies and MLOps pipelines. This role owns end to end system design with responsibility extending from single services to integrated production-grade workflows. The AI Engineer 3 emphasizes ownership of reliability observability CI/CD practices and lifecycle management with expectations to select shape and evolve architectural and operational patterns for AI systems.

• Design multi-step agent/tool workflows with clear control flow (planning vs execution separation).
• Select and implement retrieval strategies appropriate to the domain: hybrid retrieval (BM25 + vectors) multi-hop retrieval and catching.
• Implement safe rollout patterns: feature flags canaries phased traffic shifting and automated rollback triggers.
• Deliver production AI systems are integrated with core platforms (CRM/ECM) using high-availability patterns and graceful degradation.
• Define and enforce service-level objectives: latency budgets error budgets and cost budgets.
• Apply threat modeling to agent workflows and retrieval pipelines identifying risks such as prompt injection data exfiltration and context poisoning.
