Software Engineering Manager, AI Observability & Evals Platform (New York, NY)

Engineering management of the LangSmith team, which the posting describes as owning and building LangChain's core platform for observability, evaluation and production reliability of AI systems — from tracing through to evals. The role is framed as growing a team while staying close to the code: mentorship and engineering culture sit alongside long-term technical direction. It is a New York role, and a management counterpart to the principal engineering position on the same platform.
