Research Engineer at Judgment Labs | San Francisco

At Judgment Labs, we are at the forefront of developing Infrastructure for Agent Behavior Monitoring (ABM). Unlike traditional observability which primarily captures logging exceptions and latency, our innovative ABM technology identifies behavioral anomalies—such as instruction drifts and context retrieval loss—within scaled production environments.Numerous teams creating autonomous agents depend on Judgment to gain insights into their systems' post-deployment behaviors. Rather than responding reactively to incidents, our clients can analyze patterns across conversations and workflows, correlate regressions to specific interaction types, and accurately identify where reliability falters in their operational context.Recently, we successfully raised over $30M across two funding rounds in just five months. Our esteemed investors include top-tier firms and individuals such as Lightspeed, SV Angel, Valor Equity Partners, and many others.The Role:We are seeking a highly motivated Product Engineer with a minimum of 2 years of experience to join our dynamic team. This role is vital for expanding our product offerings to cater to growing customer demand while upholding our commitment to delivering an outstanding user experience in the fast-paced AI agent domain. We are looking for someone passionate about enhancing agent behavior and contributing to a product that is powerful yet enjoyable to use.What You’ll Do:Collaborate closely with our design team to develop new features and refine existing user flows based on user feedback.Engage with customers to capture their needs, gather insights, and propose new features.Develop core product features on both the front-end and back-end, including database interactions.Experiment with new features and technologies, delivering quick demonstrations for the team, and implementing promising solutions.Participate in product design reviews to ensure a high-quality and intuitive user experience.Why Judgment?Essential for Agents: Today's agents face challenges such as hallucination and drift in production. We are building the monitoring infrastructure that allows agents to improve autonomously.Driven to Succeed: Our small but mighty team of fewer than 20 operates with the efficiency of a larger team, delivering daily. You will collaborate with olympiad medalists, debate champions, and competitive athletes who all maintain the same intensity in building the company.

At Judgment Labs, we are pioneering the way that Agent Behavior Monitoring (ABM) is approached. Unlike conventional observability methods that primarily focus on logging exceptions and latency, our innovative ABM technology identifies behavioral anomalies such as instruction drifts and context retrieval losses in large-scale production environments.Our platform is trusted by numerous teams developing autonomous agents, enabling them to gain insights into system behavior post-deployment. By moving beyond reactive incident management, our users can analyze patterns across conversations and workflows, correlate regressions to specific interaction types, and accurately identify where reliability issues arise within their operational context.Recent funding success: We have successfully raised over $30M across two funding rounds within the last five months, attracting notable investors such as Lightspeed, SV Angel, Valor Equity Partners, and more.
