Senior DevOps Engineer

• Blockchain node fleet: operate validator, sentry, seed, RPC and archive nodes, including peering topology, snapshots, sync and client upgrades.

• Networking and edge: VPC design, load balancers, DNS, Cloudflare Workers, Tunnels and WAF, and keeping internet egress deliberate and cheap.

• Infrastructure as code and CI/CD: every environment defined in Terraform or Pulumi. You design and run CI/CD on Jenkins or an equivalent such as GitHub Actions or GitLab CI, covering…
