It provides reliable, self-service foundations for engineering teams and works on a small, senior-leaning team where infrastructure decisions directly affect reliability, performance, cost, and developer velocity.
Requirements
- At least 5 years of experience operating large-scale cloud infrastructure; AWS is strongly preferred.
- Deep infrastructure-as-code experience with Terraform/OpenTofu; experience with CloudFormation, Pulumi, or CDK is also relevant.
- Strong production experience with Docker and Kubernetes, including EKS.
- Proficiency in scripting or automation with Python, Go, or Bash.
- Solid cloud networking fundamentals, including VPC, DNS, load balancing, ingress, firewalls/WAF, and VPNs, and knowledge of security best practices.
- Proven CI/CD and GitOps experience with GitHub Actions or similar tools.
- Observability experience with metrics, logs, and traces, used to drive real decisions.
- A track record of independently leading infrastructure projects end to end.
- Strong communication skills with technical and non-technical audiences.
Nice To Haves
- Experience with ArgoCD, Atlantis, Linkerd/Envoy, Traefik, Karpenter, or Helm.
- Experience with OpenTelemetry, SigNoz, Grafana, Datadog, or Prometheus.
- Backstage or other internal developer platform experience.
- AI/ML infrastructure experience, such as GPU scheduling, model or agent hosting, or inference gateways.
- Rust service CI/CD experience or CloudFront/CDN experience.
- AWS Solutions Architect or DevOps Engineer – Professional certification.
- Distributed-systems background or open-source infrastructure contributions.
Responsibilities
- Design, build, and operate secure, highly available AWS infrastructure using Terraform/OpenTofu and a GitOps workflow with Atlantis.
- Own capacity planning, disaster recovery, and cost optimization for the systems in operation.
- Operate and evolve EKS, including autoscaling with Karpenter, upgrades, core add-ons, and Helm-based delivery with ArgoCD.
- Build and maintain GitHub Actions pipelines that enable platform and product teams to ship safely and quickly; provide self-service tooling where appropriate.
- Own ingress and egress, service mesh and mTLS, load balancing, edge TLS, and DNS.
- Build observability with OpenTelemetry and SigNoz, and use telemetry to guide reliability, performance, and cost decisions.
- Serve as an escalation point for complex incidents, leading troubleshooting and post-mortems.
- Apply cloud security best practices across identity, secrets, and network boundaries, with particular care for student data and K-12 privacy.
- Operate security posture and vulnerability tooling, including Security Hub, GuardDuty, Inspector, and Snyk, as well as organizational guardrails such as Control Tower and SCPs.
- Set standards, mentor engineers, and continuously improve the platform.
