Job Description

About Judgment Labs

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.

About the Role

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.

What You'll Own

• 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

Requirements

Must-Have

• 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-Have

• 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

• Salary: $200,000 – $350,000
• Experience: 3–7 years
• Visa: H-1B sponsored
• Location: San Francisco FiDi — 5 days in-person
• Equity: Competitive

Benefits & Perks

• Full benefits package
• Equinox membership
• Private chef
• Work with cutting-edge AI infrastructure
• Direct customer interaction and fast track to founding experience
