Principal Engineer in Technical Fellow Office

Join the Technical Fellow Office to solve hard, ambiguous problems, set the bar for technical excellence, and shape how the broader engineering organization builds — across teams and beyond our immediate department. You will work at the intersection of large-scale distributed systems and the frontier of agentic AI, architecting the platforms, workflows, and guardrails that let autonomous and human-in-the-loop AI systems do real work at scale.

If you want to work where cutting-edge AI meets production-grade engineering — and influence how an entire division builds — this is that role.

**What You'll Do**

+ Architect & build: Lead the design of critical systems — agentic pipelines, orchestration platforms, and the services around them — running design reviews and contributing hands-on to development.
+ Ship agentic systems: Productionize LLM-powered workflows — multi-agent orchestration, tool use, retrieval/knowledge systems, and human-in-the-loop control pla...
