Lead Network Engineer

About Us At Providence Global Center Hyderabad, we build and operate highly reliable, secure, and scalable enterprise network platforms that support mission‑critical applications across on‑premises and hybrid cloud environments. We are looking for a hands‑on SD‑WAN / WAN Engineer to support and operate large‑scale enterprise WAN environments spanning campus, clinics, and hospital locations. This role focuses on day‑to‑day SD‑WAN stability, BGP‑based routing, incident response, lifecycle management, and automation, with exposure to multiple SD‑WAN platforms such as VMware VeloCloud, Cisco SD‑WAN (Viptela), Fortinet, Aruba/Silver Peak, or similar technologies. Key Responsibilities Provide L2/L3 operational support for WAN and SD‑WAN services across geographically distributed sites using platforms such as VMware VeloCloud (preferred), Cisco SD‑WAN, Fortinet Secure SD‑WAN, Aruba EdgeConnect, or equivalent. Participate in On‑Call rotation (including weekends/after hours as required) to restore WAN outages and critical connectivity incidents within SLA. Monitor WAN and SD‑WAN health using tools such as SolarWinds, VeloCloud Orchestrator, Cisco vManage, FortiManager/FortiAnalyzer, and act on performance, stability, and compliance issues. Own internet edge and site‑to‑site connectivity, ensuring redundancy using dual ISPs, HA designs, and optimal routing/path selection. Troubleshoot Layer‑3 WAN issues, including BGP peering, routing convergence, failover behavior, packet loss, latency, jitter, and path selection. Support SD‑WAN overlay and underlay troubleshooting, tunnel stability, and application‑aware routing policies. Drive DPMO and service reliability improvements by identifying recurring WAN defects and implementing preventive fixes. Execute WAN Get‑Well initiatives, including EOL/EOS router replacements and SD‑WAN edge refresh programs. Perform Cisco IOS upgrades, SD‑WAN edge software upgrades, and assist with WAN hardware lifecycle management. Plan and execute maintenance window activities, including WAN cutovers, SD‑WAN turn‑ups, migrations, ISP transitions, and post‑change validation. Create and follow Method of Procedure (MOP) documents and coordinate with ISPs, carriers, and field engineers. Ensure configuration standardization and compliance across WAN routers and SD‑WAN devices. Support incident, problem, and RCA processes, with clear documentation and stakeholder communication. Work closely with LAN, Wireless, Security, Voice, and Service Desk teams to ensure end‑to‑end connectivity and application reachability. Support network segmentation and security integration, coordinating routing and traffic‑steering with firewall and security teams. Identify opportunities to automate WAN and SD‑WAN operations using Python, Ansible, or similar tools. What Would Your Day Look Like? Review WAN/SD‑WAN health dashboards, ISP status, BGP adjacencies, and alerts at the start of the day. Handle incidents involving ISP failures, BGP instability, SD‑WAN tunnel drops, and application performance issues. Proactively monitor routing stability and failover/path optimization behavior. Work with ISPs, telcos, and site teams to resolve circuit and last‑mile issues. Analyze recurring WAN defects and contribute to continuous improvement initiatives. Execute planned maintenance such as IOS upgrades, SD‑WAN edge upgrades, new site turn‑ups, and router refreshes. Prepare and execute MOP‑based changes, perform validations, and share post‑change reports. Participate in On‑Call support, providing timely restoration, updates, and RCAs. Develop or enhance automation scripts to reduce manual WAN/SD‑WAN operational effort. Who Are We Looking For? Bachelor’s Degree (or equivalent) in Engineering / Technology. 6-9 years of enterprise networking experience , with: 6+ years of hands‑on WAN / SD‑WAN operational experience Experience working on router lifecycle, refresh, or EOL/EOS activities 4+ years of BGP‑based WAN routing experience Hands‑on exposure to SD‑WAN platforms such as VMware VeloCloud (preferred), Cisco SD‑WAN (Viptela), Fortinet, Aruba/Silver Peak, or similar Strong understanding of WAN fundamentals: BGP, QoS, NAT, ACLs, IP SLA, ISP redundancy, and HA designs. Experience supporting large or distributed enterprise WAN environments. Comfortable troubleshooting routing, SD‑WAN overlay/underlay, ISP, and application‑path issues. Proactive mindset with ability to identify recurring issues and improve reliability. Experience executing planned maintenance, software upgrades, and hardware refreshes. Disciplined approach to configuration standards and documentation. Willingness to participate in On‑Call rotations. Exposure to automation using Python, Ansible, or similar tools is strongly preferred.
