Full Job Posting

Nice to Have

  • ArgoCD, Atlantis, Linkerd/Envoy, Traefik, Karpenter, Helm
  • OpenTelemetry, SigNoz (our stack), Grafana, Datadog, or Prometheus
  • Backstage or other internal developer platform experience
  • AI/ML infra experience (GPU scheduling, model/agent hosting, inference gateways)
  • Rust service CI/CD, CloudFront/CDN experience
  • AWS Solutions Architect / DevOps Engineer – Professional certification
  • Distributed-systems background, OSS infrastructure contributions

Responsibilities

  • Cloud Infrastructure & IaC — Design, build, and operate secure, highly available AWS infrastructure using Terraform/OpenTofu with a GitOps workflow (Atlantis). Own capacity planning, DR, and cost optimization for the systems you run.
  • Kubernetes & Platform Operations — Operate and evolve EKS: autoscaling (Karpenter), upgrades, core add-ons, and Helm-based delivery (ArgoCD).
  • CI/CD & Developer Enablement — Build and maintain GitHub Actions pipelines that let platform and product teams ship fast and safely, with self-service tooling where it makes sense.
  • Networking, Ingress & DNS — Own ingress/egress (Traefik), service mesh and mTLS (Linkerd/Envoy), load balancing, edge TLS, and DNS (Route 53, Terraform-managed).
  • Observability & Reliability — Build observability with OpenTelemetry and SigNoz; use telemetry to drive reliability, performance, and cost decisions. Serve as an escalation point for complex incidents, leading troubleshooting and post-mortems.
  • Security & Compliance — Apply cloud security best practices across identity, secrets, and network boundaries, with particular care for student data and K-12 privacy. Operate posture/vulnerability tooling (Security Hub, GuardDuty, Inspector, Snyk) and org guardrails (Control Tower, SCPs).
  • Ownership & Mentorship — Set standards, mentor engineers, and leave the platform better than you found it.
  • 5+ years operating large-scale cloud infrastructure (AWS strongly preferred)
  • Deep IaC experience (Terraform/OpenTofu; CloudFormation/Pulumi/CDK also relevant)
  • Strong Docker/Kubernetes (EKS) production experience
  • Scripting/automation proficiency (Python, Go, or Bash)
  • Solid cloud networking fundamentals (VPC, DNS, load balancing, ingress, firewalls/WAF, VPNs) and security best practices
  • Proven CI/CD and GitOps experience (GitHub Actions or similar)
  • Observability experience (metrics/logs/traces) used to drive real decisions
  • Track record leading infrastructure projects independently, end to end
  • Strong communication across technical and non-technical audiences
