About The Position

Judgment Labs builds infrastructure for Agent Behavior Monitoring (ABM). While traditional observability focuses on logging exceptions and latency, Judgment's ABM surfaces behavioral anomalies — instruction drift, context retrieval loss — in production at scale. Hundreds of teams building autonomous agents rely on Judgment to understand how their systems behave post-deployment. Raised $30M+ across two rounds in the past five months from Lightspeed, SV Angel, Valor Equity Partners, Michael Ovitz, Kevin Hartz, and others. Judgment Labs is hiring an Agent Product Engineer to build high-taste products for self-learning agents. The role is majority agent work with a baseline of full-stack engineering. Candidates can come from a front-end/design engineering background or an AI engineering background, but both must have prior experience building and designing agents, preferably at a startup with 0-1 product ownership.

Requirements

3–7 years of software engineering experience
Prior experience building and designing agents (Applied AI / agent engineering background) — production work, not hackathon projects
Solid product engineering capabilities; ships features end-to-end
Strong customer-facing communication skills
Comfort with 0-1 product work and ambiguity
Basic full-stack engineering ability
Based in SF or willing to relocate; 5 days in office in FiDi

Nice To Haves

Prior evals, observability, or behavior-monitoring product experience (heavily preferred)
TypeScript fluency
Prior Series A or seed startup experience
Strong design taste at consumer-grade product polish levels

Responsibilities

Design and ship agentic product surfaces used by hundreds of engineering teams
Build, evaluate, and improve agents that power Judgment's self-learning loops
Create intuitive, polished UI/UX for complex behavioral monitoring data
Work directly with customers to understand how they interact with agents in production
Drive evals, observability, and behavior-monitoring product features
