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

Aparna Dhinakaran of Arize AI argues that the AI engineer's job is shifting from writing features to building the loop that builds them: evals that review non-deterministic work, telemetry that agents consume, and always-on agents that act on it. She uses Arize's Signal agent as a case study, covering triggers, sandboxes, durable state, model and harness independence, and evaluating the evaluators.
