Judgment is the learning infrastructure for AI agents. Agents in production don't improve from prompts alone. They improve from experience: the tasks they attempt, the mistakes they make, the edge cases they hit. Here's how it works:
We ingest everything your agents do in production: traces, tool calls, decisions, outcomes
Judgment turns that raw experience into structured signals: failure modes, behaviors, rubrics, evals
Teams close the loop, shipping agent improvements validated against real production evidence
You'll own problems end-to-end: talking to customers, defining what to build, building it, and iterating until it's great. This is not a role where you implement specs handed down.
What You Will AccomplishInvestigation interfaces: Design how engineers understand what their systems did and why. Long traces, tool calls, decisions, failures. How do you make a complex sequence of events legible in minutes?
Verification: Build the platform for verifying system changes: hosted simulated environments, trajectory replay, and monitors for unintended behavior changes.
The improvement loop: Build the workflows that turn production data into datasets, evaluations, and regression checks, so the path from "found a problem" to "verified a fix" feels like one motion.
The platform underneath: Workspaces, roles, permissions, billing, usage, and limits for teams running many workflows across many environments.
Experience building and scaling end-to-end production systems, from data layer to UI

What We Do
Judgment Labs builds agent behavior monitoring (ABM) infrastructure. Judgment provides a toolkit to track and judge agent behavior in online and offline setups, enabling you to convert high-signal interaction data from production/test environments into more reliable agents.
