• Deep understanding of network protocols (BGP, OSPF, EIGRP, STP, VXLAN, VPNs, QoS, MPLS, etc.).
• Strong experience with infrastructure automation using Ansible and Salt.
• Proficiency with observability tooling such as Grafana, Splunk, or equivalent.
• Solid understanding of SRE practices including SLIs, SLOs, error budgets, and proactive reliability.
• Strong troubleshooting, analytical, and performance optimization skills.
• Excellent communication and collaboration skills, with the ability to influence and guide technical stakeholders.

Nice to Have

• Experience with network programmability (Python, API‑driven networking, NetConf/RESTConf).
• Exposure to cloud networking (AWS, Azure, GCP).
• Knowledge of zero‑trust, SD‑WAN, and network security best practices.
• Experience creating self‑healing or fully automated network workflows.
