As part of the Optum Health Financial Tech team, the Architect will define and own the end-to-end architecture for AI-enabled and Generative AI solutions aligned with business outcomes, scalability, security, and enterprise compliance. In this role, you will design reference architectures for LLM-based systems (including prompt orchestration, Retrieval-Augmented Generation [RAG], and agent frameworks), evaluate foundation models and AI platforms, and integrate advanced AI capabilities into existing microservices and event-driven data platforms.

You will serve as the technical authority across cross-functional engineering teams to drive AI innovation, enforce Responsible AI principles, and deliver scalable, high-performance solution designs.

You’ll enjoy the flexibility to work remotely
