The Role
Lumen is seeking a Lead Site Reliability Engineer (SRE) who will be a catalyst for transformational change and operational excellence. The ideal candidate not only builds and operates systems but proactively identifies gaps, challenges legacy approaches, and delivers high-impact changes that improve customer experience. You will own platform engineering standards across Azure Public and Azure Government clouds, lead the design of CI/CD and observability systems, and partner closely with development teams to deliver scalable, secure, and compliant high-availability services.
Location
- This role is designated as a fully remote position within the United States.
The Main Responsibilities
- Design, build, and operate AKS clusters with enterprise guardrails (RBAC, pod security policies, node pools, autoscaling, upgrade strategies).
- Implement GitOps with Flux CD; define Helm chart standards and manage lifecycle via Helm 3.
- Own container platform best practices: Docker image standards, multi-stage builds, SBOM, vulnerability scanning, and base image governance.
- Configure Nginx (ingress controller) and Kong (API gateway) including routing, rate limiting, mutual TLS, JWT/OAuth2 auth, and WAF integration.
- Stand up Prometheus for metrics scraping, alert rules, and exporters; integrate Grafana for dashboards and SLO/SLA visualization.
- Lead Jenkins pipeline automation and GitHub Actions workflows for build/test/deploy, with reusable templates and environment promotion strategies.
- Build infrastructure-as-code and policy-as-code pipelines using Terraform (or similar tools like Bicep), with automated validations, PR gates, and compliance checks.
- Architect and enforce secure integration with Azure Key Vault for secret, key, and certificate management; automate cert-manager/issuer (ACME/PFX).
