+ Automate provisioning, configuration, and monitoring tasks using Python, Go, Bash, and PowerShell, integrating with AWS Lambda, GCP Cloud Functions, and Azure Functions.
+ Collaborate with SRE, cloud security, and platform teams to ensure alignment with zero trust, compliance frameworks, and cloud-native security controls.
+ Solve sophisticated hybrid networking issues across LAN, WAN, cloud interconnects, Internet, and routing protocols (BGP, OSPF, EVPN, VXLAN).
+ Implement cloud load balancers, CDN integrations, DNS failover, and traffic steering policies for high availability and global resiliency.
+ Evaluate and deploy next-gen technologies, including service mesh, cloud-managed firewalls, cloud-native monitoring, and observability platforms.
+ Drive adoption of guidelines for cost optimization, tagging strategies, and governance across multi-cloud infrastructure.
+ Continuously evaluate current systems, pinpoint opportunities for improvement, and put in place effective solutions for automation.
+ Standardize documentation, runbooks, and design patterns for network and cloud operations.

**Who You Are**

+ **What you’ll bring with you:**
+ 10+ years of experience supporting high-performance production environments.
+ 3–5 years of hands-on cloud networking experience across AWS, GCP, and Azure.
+ Demonstrable experience designing and operating secure hybrid multi-cloud networks, including site-to-site VPNs, ExpressRoute, Direct Connect, Cloud Interconnect, and Transit Gateway topologies.
+ Strong programming and automation skills in Python, with experience in network automation frameworks and cloud SDKs/APIs (boto3, gcloud, azure-cli).
