About the Role As an LLM Systems / AI Agent Engineer, you will focus on building and evolving production AI agents on foundation models, covering orchestration, context engineering, evaluation pipelines, and production observability and monitoring. This is an LLM systems and AI agent engineering position rather than a traditional ML model-training role. You will be the first dedicated AI-agenting hire, working directly alongside the engineer who currently leads this function. The product currently uses a custom orchestration layer, and your knowledge of agent architecture patterns will help inform whether to continue with this approach or adopt a production framework such as LangGraph or LangChain. Roadmap timings are somewhat tentative, but you will be assigned measurable deliverables immediately upon onboarding.
