Note: The job is a remote job and is open to candidates in USA. Category Labs is a team of systems engineers and researchers focused on decentralized technology and blockchain solutions. They are seeking a Senior DevOps / Infrastructure Engineer to manage their infrastructure and leverage AI to enhance operations.
Responsibilities
- 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 pipeline: node upgrades, canary rollouts, snapshot/restore, and the guardrails that bound blast radius (e.g., protecting validators from automated changes)
- Design and build agentic operations: develop AI agents, tooling (e.g., MCP servers), and runbooks-as-code that let agents safely investigate, diagnose, and execute routine operations, with deterministic guardrails and human oversight
- Codify operational knowledge into tools and automation that the whole team, and its agents, can reuse
- Harden nodes and services, manage secrets, and continuously drive down manual toil
Skills
- 5+ years in DevOps, SRE, or Infrastructure Engineering, operating production systems at scale
- Strong Linux, systemd, networking, and shell fundamentals, and comfortable debugging live systems over SSH
- Deep, hands-on infrastructure-as-code experience with Ansible and Terraform
- Experience with observability stacks (Prometheus, Grafana, Loki, or equivalents)
- Hands-on fluency with AI-assisted engineering: use coding agents and LLM tooling in daily workflow and have judgment on where it helps and where it's risky
- Experience designing automation with safe guardrails, and bring calm, methodical incident response
- Programming and scripting experience (e.g., Python, bash)
- Experience with Kubernetes and GitOps (Flux or Argo) is a plus
- Experience building AI agent tooling, MCP servers, or agent orchestration frameworks is a plus
- Experience serving inference, either locally or as a service is a plus
- Previous experience with blockchain clients or node operations is a plus
- A Bachelor of Science in Computer Science, Engineering, or a related field is a plus
