Performance Period: June 2026- Dec 31 2026, with the possibility of multi-year extension based on performance

This role is for a Senior Network Architect SME 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
