Senior Platform Infra Engineer: Cloud, Kubernetes & GitOps

Level; Bellevue (WA); On-site; USD 150,000 - 195,000; Full time

Job summary

Level, a learning technology company, is seeking a Senior Infrastructure Engineer to design, build, and operate the cloud platform that powers Level products. You’ll own the Kubernetes platform, IaC pipelines, CI/CD and GitOps delivery, network ingress, DNS, and cloud security posture across teams.

You will lead reliability improvements, drive capacity planning, cost optimization, and security posture while mentoring engineers and raising platform standards.

Qualifications

• 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.

Responsibilities

• Design, build, and operate secure, highly available AWS infrastructure using Terraform/OpenTofu with a GitOps workflow (Atlantis).
• Operate and evolve EKS: autoscaling (Karpenter), upgrades, core add-ons, and Helm-based delivery (ArgoCD).
• Build and maintain GitHub Actions pipelines that let platform and product teams ship fast and safely, with self-service tooling where it makes sense.
• Own ingress/egress (Traefik), service mesh and mTLS (Linkerd/Envoy), load balancing, edge TLS, and DNS (Route 53, Terraform-managed).
• Build observability with OpenTelemetry and SigNoz; use telemetry to drive reliability, performance, and cost decisions.
• Apply cloud security best practices across identity, secrets, and network boundaries, with care for student data and privacy.
