Excellent communication skills with the ability to collaborate across engineering, platform, and infrastructure teams.

Responsibilities

Design and implement enterprise-scale Network-as-Code (NaC), Infrastructure-as-Code (IaC), and GitOps solutions using Terraform, Ansible, Python, and Git as the single source of truth, eliminating manual deployment processes.
Build, optimize, and maintain CI/CD pipelines for network infrastructure, including automated testing, dry-run validation, deployment approval gates, and security/compliance checks to enable zero-downtime deployments.
Design, deploy, and support Kubernetes networking architectures, including Project Calico, OVN, VXLAN overlays, network policies, container networking, and integration with physical underlay networks.
Lead the design, modernization, and review of enterprise network architectures, providing expertise in BGP, OSPF, data center networking, multi-site routing, and high-availability solutions.
Serve as the Tier-4 escalation engineer for complex network incidents, troubleshooting overlay/underlay failures, asymmetric routing, microbursts, path selection issues, and network performance bottlenecks.
Lead root cause analysis (RCA) and drive long-term remediation and continuous improvement initiatives to enhance network reliability, scalability, and operational efficiency.
Implement Security-as-Code practices by automating validation and enforcement of ACLs, firewall policies, security groups, and configuration standards before production deployments.
