Senior DevOps / Infrastructure Engineer

Category Labs (formerly known as Monad Labs) is a team of systems engineers and researchers on a mission to design and build at the frontier of decentralized technology. We strive to deliver significant improvements over existing blockchain solutions. After raising $225M in series A funding, led by Paradigm, we are growing our team. We’re the team behind Monad, a high-performance, EVM-compatible Layer 1 whose public mainnet is now live. We write the core software that runs it: a parallel-execution EVM https://github.com/category-labs/monad, a custom state database, and a BFT consensus client https://github.com/category-labs/monad-bft, all developed in the open. THE ROLE We're looking for a Senior DevOps / Infrastructure Engineer to operate the infrastructure behind Monad, and to push how much of that operation can be driven by AI. You'll keep our globally-distributed validator, full node, and archive fleet healthy across mainnet and testnet, own our infrastructure-as-code and observability, and build the agentic tooling and guardrails that let a small team safely operate a large fleet. As more of our engineering shifts toward AI, this role is central to designing the workflows, deterministic guardrails, and security perimeters within which autonomous agents operate our infrastructure; you'll also help stand up and operate the infrastructure behind our own growing model workloads. WHAT YOU'LL DO - Operate the Monad node fleet: health, sync, upgrades, and recovery across validators, full nodes, archive/historical, and indexer nodes on mainnet and testnet, including safe, staged rollouts and incident response. - Own our infrastructure-as-code: Ansible for fleet configuration, Terraform + Atlantis for cloud and DNS, and Kubernetes/Flux (GitOps) for platform services. - Build and operate observability and alerting (Prometheus, Grafana, Loki); create dashboards and alerts that catch problems before they page while minimizing false positives. - Automate the release pipelin
