• Configure advanced switching features (STP, EtherChannel, VLAN segmentation).
• Optimize traffic engineering and QoS policies for application performance.
• Integrate SD-WAN with firewalls and security policies.
• Establish cloud-onramp connectivity with AWS/Azure using IPsec and BGP.
• Develop automation scripts (Python/Ansible) for configuration and monitoring.
• Perform root cause analysis for complex network issues and provide permanent fixes.
• Mentor L2 engineers and review their configurations.
• Maintain detailed network diagrams and configuration baselines.

Required Skills:

• 8+ years of experience in network engineering.
• 4+ years of SD-WAN experience (Silver Peak mandatory).
• Expert-level knowledge of routing (BGP, OSPF, route redistribution) and switching (L2/L3).
• Strong understanding of MPLS, IPsec, QoS, and WAN optimization.
