About the role

Role focused on building product experiences and agents to run scalable, end-to-end agent investigations and improvements within Judgment Labs’ AI agent platform.

Responsibilities

  • Judgment Agent: Shape how the Judgment Agent runs large-scale investigations across production traces and merge results into a single answer.
  • Verification: Build platform for verifying agent changes including simulated environments, trajectory replay, and monitors for unintended behavior changes.
  • Agent investigation interfaces: Design interfaces to understand agent decisions, long traces, tool calls, and reasoning; enable fast debugging of multi-step trajectories.
  • Swarm UX: Design dashboards and workflows to monitor parallel investigations and guide investigators.
  • The improvement loop: Create workflows to turn production trajectories into datasets, judges, and regression checks to streamline problem-to-fix flow.
  • The platform underneath: Develop workspaces, roles, permissions, billing, usage, and limits for multi-environment agent deployments.
  • Judgment everywhere agents are built: Provide an SDK and terminal-first experience to summon Judgment as a subagent during development.

Qualifications

  • Experience building and scaling end-to-end production systems from data layer to UI.
  • Strong technical problem-solving skills in fast-changing environments.
  • A builder and tinkerer's mindset with high agency and shipping mindset.
  • Hands-on experience building with LLMs or agents, or the drive to acquire it quickly.
  • Comfort working directly with customers to understand needs and solve real-world problems.
  • Excellent communication skills across technical and non-technical audiences.
  • Reinforcement learning, post-training, agents, or machine learning fundamentals.
