SENIOR CLOUD INFRASTRUCTURE ENGINEER San Francisco · On Site · Full Time Judgment Labs is building the infrastructure for continual learning in long-horizon AI agents. The next generation of agents will not improve from prompts alone. They will improve from experience: the tasks they attempt, the tools they use, the mistakes they make, the edge cases they encounter, and the outcomes they produce in production. The hard part is turning that raw experience into high-quality data that can actually improve the system. Judgment builds the infrastructure to do that. We turn long agent trajectories into clean, structured data for evals, labeling, rubric generation, context engineering, and RL workflows. Instead of only showing teams what happened, Judgment helps decide what matters, what should be learned from, and how that learning should flow back into the agent. Databricks built the data infrastructure for analytics. Judgment is building the learning infrastructure for agents. We’ve raised $30M+ from Lightspeed, SV Angel, Valor Equity Partners, and others. THE ROLE We’re looking for a Senior Cloud Infrastructure Engineer to own the infrastructure that lets Judgment run reliably across our cloud, customer environments, and enterprise deployments. This role focuses on cloud/platform infrastructure: Terraform, EKS, ArgoCD/Kargo, IAM, DNS, observability, CI/CD, multi-region architecture, BYOC, self-hosted deployments, private connectivity, and enterprise-grade reliability. You’ll work on the systems that keep high-throughput telemetry ingestion, ClickHouse, RabbitMQ, Temporal, evaluation workers, and customer-facing services running under real production load. You’ll also make Judgment deployable for customers with strict security and infrastructure requirements: multi-region, data residency, private networking, self-hosted, air-gapped, and Bring Your Own Cloud environments. INTERESTING TECHNICAL CHALLENGES - Enterprise-grade deployment architecture. Run Judgment in customer environments — self-hosted, air-gapped, or BYOC — while keeping operations, upgrades, observability, and reliability sane. - Multi-region reliability. Design failover, disaster recovery, data residency, and deployment patterns for customers that cannot tolerate downtime or ambiguous data movement. - Infrastructure for high-throughput telemetry. Support ingestion systems parsing and persisting hundreds of thousands of spans per second, with graceful backpressure and clear failure modes. - Operating stateful systems at scale. Keep ClickHouse, RabbitMQ, Temporal, evaluation workers, and supporting services healthy as workloads grow and customer traffic becomes spiky. - Private and secure connectivity. Build secure paths into customer environments using network isolation, IAM, SSO/SAML/SCIM, encryption, private connectivity, and restricted-network deployment patterns. - A single operational story across many deployment modes. Cloud, multi-region, BYOC, and self-hosted deployments should not become four totally different products to operate. - Safe production rollouts. Build deployment automation, environment parity, feature-flag discipline, CI/e2e reliability, monitoring, and rollback mechanisms so the team can move fast without breaking customer trust. WHAT YOU’LL DO - Own cloud infrastructure for production services across Terraform, EKS, ArgoCD/Kargo, IAM, DNS, networking, metrics, CI/CD, and deployment automation. - Build and operate infrastructure for trace ingestion, evaluation workers, RabbitMQ, Temporal, ClickHouse, and the systems that support Judgment’s core product. - Design multi-region and enterprise deployment architectures, including data residency, automatic failover, disaster recovery, and customer-managed environments. - Build secure deployment patterns for BYOC, self-hosted, private-network, and restricted environments. - Implement private connectivity, identity integrations, network isolation
