What you’ll do

  • Architect, build, and run resilient, scalable cloud infrastructure; drive AWS Well-Architected pillars (operational excellence, security, reliability, performance, cost, sustainability). 
  • Champion GitOps (e.g., Argo CD): declarative configs, PR-driven changes, continuous reconciliation. 
  • Implement and evolve CI/CD (GitHub Actions/Argo CD), secrets management, policy-as-code, and environment promotion.

  • Lead/mentor engineers; drive Terraform standards, modules, and reviews. 
  • Optimize cost and efficiency (FinOps) while maintaining reliability.

Requirements

What you bring (must-haves)

  • 5+ years hands-on DevOps/SRE in large-scale production.
  • Deep production experience: AWS (or major public cloud), Kubernetes, Terraform.
  • Proven ownership: design → implement → release → operate → improve (independent and team-based).
  • Excellent communication; comfortable collaborating with external stakeholders.

Nice to have

  • Linux, networking (DNS/HTTP/TCP/IP), and security fundamentals.
  • CI/CD with GitHub Actions/Argo CD; service mesh; policy-as-code.
  • Observability: OpenTelemetry, Prometheus, Grafana.
