Senior Infrastructure Engineer

Level
Bellevue, WA
On-site

Who this role is best for

Best suited to experienced cloud architects with a focus on automation and observability working in the education technology domain.

Best fit for

  • Experienced cloud architects with a track record in end-to-end infrastructure ownership
    — “own critical infrastructure end-to-end — the Kubernetes platform, infrastructure-as-code, CI/CD and GitOps delivery”
  • Candidates with strong automation and observability expertise in cloud environments
    — “Build observability with OpenTelemetry and SigNoz; use telemetry to drive reliability, performance, and cost decisions”
  • Individuals who thrive in small, senior-leaning teams with direct impact on platform reliability
    — “you will work on a small, senior-leaning team where infrastructure decisions have direct, visible impact”

Things to consider

  • The role demands strong cross-functional communication, including non-technical stakeholders
    — “Strong communication across technical and non-technical audiences”
  • Expect a high level of responsibility in areas like cloud security and incident escalation
    — “Serve as an escalation point for complex incidents, leading troubleshooting and post-mortems”

How to stand out

  • Highlight your experience with GitOps tools like Atlantis and ArgoCD in your resume and interviews
    — “operate with a GitOps workflow (Atlantis)”
  • Demonstrate your ability to lead end-to-end infrastructure projects independently
    — “Track record leading infrastructure projects independently, end to end”
  • Emphasize your hands-on experience with EKS, Karpenter, and Helm-based delivery
    — “Operate and evolve EKS: autoscaling (Karpenter), upgrades, core add-ons, and Helm-based delivery”
  • Showcase your use of telemetry data to make infrastructure decisions
    — “use telemetry to drive reliability, performance, and cost decisions”
  • Demonstrate your skills in cloud networking and security, particularly with AWS tools
    — “Solid cloud networking fundamentals (VPC, DNS, load balancing, ingress, firewalls/WAF, VPNs) and security best practices”

About Level

Level is a learning technology company dedicated to helping students build real academic and life skills with confidence and joy. We combine proven curriculum principles with world class interactive design to make meaningful practice something students want to come back to, not something they struggle through. We support what teachers, schools, and parents are already doing by increasing student engagement with high quality, standards aligned practice that reinforces classroom learning.

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.

What You'll Do

  • 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.

What You Need

  • 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

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
