## Description

Judgment Labs builds infrastructure for Agent Behavior Monitoring (ABM). Where traditional observability logs exceptions and latency, Judgment surfaces behavioral anomalies such as instruction drift and context-retrieval loss in production AI agents at scale, and hundreds of agent-building teams rely on it.

The company has raised $30M+ across its seed and Series A, led by Lightspeed with SV Angel, Valor Equity Partners, Nova Global and angels including Chris Manning, Michael Ovitz and Kevin Hartz.

The Role

This is a critical early senior hire to mature Judgment's software systems and engineering practices as the company scales. You will be a hands-on technical leader, writing code daily while shaping architecture, code quality and deployment standards, working deeply in backend systems and OLAP infrastructure (ClickHouse), mentoring a growing team, and partnering with the founders on scalability and reliability.

What You Will Do

 * Lead backend development hands-on while guiding architecture and design decisions.
 * Improve code quality, reduce technical debt and implement scalable practices as volume grows.
 * Build and optimize backend systems on columnar/OLAP databases such as ClickHouse.
 * Mentor engineers and raise engineering maturity.
 * Partner with the founders on reliability, scalability and deployment decisions.
