Description:

Senior Network Architect

This role is for a senior network architect with deep expertise in routing and a strong operational mindset. The ideal candidate is not only a subject matter expert in BGP, OSPF and VXLANs, but also a well rounded network engineer who can support day-to-day operations, contribute to security and visibility platforms, and drive innovative improvements across the network.
You will be expected to take ownership of critical portions of the network, make high-impact design decisions, and execute changes in live environments without introducing instability.

Responsibilities & Qualifications
Own and evolve enterprise routing architecture with deep expertise in BGP and OSPF, including policy design, traffic engineering, convergence behavior, and failure handling at scale
Design, implement, and operate modern data center fabrics (spine-leaf, VXLAN/EVPN) including integration with cloud and virtual infrastructure platforms with a focus on stability, scalability, and operational simplicity
Lead and execute complex network changes and migrations in production environments with near-zero service impact
Act as a top-tier escalation point, driving issues from ambiguous symptoms to root cause across routing, switching, security, and application layers
Operate seamlessly between architecture and hands-on troubleshooting, including deep packet analysis (Wireshark/PCAP) and system-level debugging
Design and enhance network segmentation, access control, and visibility using technologies such as Cisco ISE and Gigamon
Integrate and support secure access and edge solutions (e.g., Zscaler, Cisco FTD) within the broader network architecture
Evaluate existing designs and proactively propose improvements to reliability, performance, and operational efficiency
Demonstrate CCIE-level expertise (certification not required), with proven experience designing and operating large-scale production networks
Strong hands-on experience with Cisco platforms (Nexus, Catalyst, NX-OS, IOS-XE)
Practical experience with NAC (Cisco ISE or equivalent) and network visibility tools (Gigamon or similar)
Deep understanding of TCP/IP and packet-level behavior, with the ability to troubleshoot under real production pressure
