What Does an AI Engineer Do Now? - Aparna Dhinakaran, Arize AI

Why watch

Aparna Dhinakaran explains how AI engineering has evolved from feature writing to building agent factories. The video covers Arize AI's Signal agent - an always-on system that reads traces, identifies issues from historical patterns, and autonomously opens pull requests. Key topics include trigger mechanisms for agent activation, sandbox execution design, durable state persistence across agent runs, and building eval frameworks to assess agent quality itself. Ideal for engineers building production AI agents who need observability and autonomous remediation.
