Job summary

Category Labs is seeking a Senior DevOps / Infrastructure Engineer to operate Monad’s globally-distributed infrastructure, combining AI-guided workflows with robust guardrails. You will own IaC tooling, observe fleet health, and drive automation to reduce toil across mainnet and testnet.

You should bring 5+ years in DevOps/SRE, strong Linux and scripting skills, and hands-on experience with Ansible, Terraform, Kubernetes, and GitOps.

Qualifications

• 5+ years in DevOps, SRE, or Infrastructure Engineering, operating production systems at scale.
• Strong Linux, systemd, networking, and shell fundamentals; comfortable debugging live systems over SSH.
• Hands-on infrastructure-as-code experience with Ansible and Terraform.
• Observability stacks experience (Prometheus, Grafana, Loki).
• Hands-on fluency with AI-assisted engineering; using coding agents and LLM tooling.
• Experience designing automation with safe guardrails and incident response.
• Programming/scripting experience (Python, Bash).
• 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.

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.
