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
Qualification
Required
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)
Preferred
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
