Define and enforce the organization's Infrastructure-as-Code standards using Terraform and Ansible; drive adoption of GitOps workflows. Build and maintain CI/CD and automated deployment pipelines for all services and applications across environments. Evaluate and introduce emerging technologies (eBPF, WASM, service meshes) to improve platform capabilities. Partner with engineering leadership to embed reliability requirements into the SDLC; champion chaos engineering and resilience testing programs. Mentor and grow mid-level and junior SREs across global teams through code reviews, pairing, and structured knowledge sharing. Drive capacity planning, cost optimization, and FinOps practices across the AWS environment. Contribute to the engineering roadmap and help define the long-term reliability strategy for the CWAN platform.
