Senior Network Engineer II

We are looking for an experienced network engineering leader to help drive the design, modernization, support, and evolution of Nielsen’s enterprise network environment in India. This role is not limited to end-user experience. It is a broad technical lead role spanning network architecture, core infrastructure modernization, VPN transformation, network segmentation, security controls, operational stability, and cross-functional delivery. You will serve as a technical lead across both project and operational domains, partnering with network engineering, NOC, cybersecurity, cloud/platform teams, application owners, local IT, and support teams to deliver secure, scalable, and resilient network services. This person should be equally comfortable working in product-oriented environments that prioritize speed and roadmap execution, and in support-oriented organizations that require operational rigor, incident response, stability, and service excellence. Role overview This position will lead technical direction across enterprise networking initiatives, with a strong focus on architecture, modernization, and execution. The successful candidate will help evolve legacy environments into well-governed, enterprise-grade network platforms while also supporting ongoing production operations and mentoring engineers across the team. Key responsibilities Lead network architecture and modernization initiatives across campus, branch, datacenter, internet edge, remote access, and hybrid cloud connectivity environments. Act as the technical lead for VPN strategy and transformation, including modernization of remote access models, alignment with next-generation firewall capabilities, and improvements to secure user and site connectivity. Drive network segmentation initiatives to improve security posture, limit lateral movement, and establish risk-based trust zones and access controls without disrupting business operations. Partner with cybersecurity, application teams, server owners, and change management teams to design, test, and implement network changes in a controlled and pragmatic manner. Provide technical leadership across routing, switching, DNS, DHCP, wireless, firewalling, authentication, and access control domains. Support the evolution of enterprise and cloud networking patterns, including hybrid connectivity, governance, scalability, and performance optimization. Act as a senior escalation point for complex network incidents, chronic issues, and cross-functional troubleshooting involving support, operations, and engineering teams. Create and maintain network diagrams, traffic flow maps, standards, SOPs, and implementation documentation. Use traffic analysis, telemetry, firewall logs, and network data sources to identify bottlenecks, reduce risk, and improve performance and reliability. Mentor other engineers, influence technical direction, and help establish best practices that balance product agility with enterprise reliability and governance.

12+ years of hands-on experience in network engineering, network architecture, and production support in medium to large enterprise environments. Proven experience operating as a technical lead or senior engineer across both project delivery and business-as-usual support models. Prior experience working in both product-oriented organizations and support/service-oriented organizations. Strong background in core networking, including routing, switching, DNS, DHCP, and enterprise wireless. Strong experience with VPN technologies, remote access architecture, firewall policy design, and network security controls. Experience leading or materially contributing to network segmentation, access control, and zero trust or trust-zone initiatives. Excellent troubleshooting skills and the ability to lead high-severity issue resolution across multiple teams. Experience with authentication and network access technologies such as 802.1x, NAC, RADIUS, and EAP-TLS. Strong communication and stakeholder management
