## Description

As an Senior Infrastructure Engineer on the Platform team, you will architect, build, and operate the cloud infrastructure and developer platform that every Level product runs on. You will own critical infrastructure end-to-end - the Kubernetes platform, infrastructure-as-code, CI/CD and GitOps delivery, networking (ingress and egress), DNS, observability, and cloud security posture - and provide the reliable, self-service foundations the rest of engineering builds on. You will work on a small, senior-leaning team where infrastructure decisions have direct, visible impact on reliability, performance, cost, and developer velocity., * 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.
