ECCO Select is seeking a Senior Network Architect (Subject Matter Expert) to support a key customer initiative. This role requires deep technical expertise in enterprise routing and modern data center networking, combined with a strong operational mindset.

The ideal candidate is a hands-on architect who can design, implement, and support complex network environments while maintaining stability in live production systems. This individual will play a critical role in shaping network strategy, driving innovation, and ensuring high availability across enterprise infrastructure.

Key Responsibilities

• Own and evolve enterprise routing architecture with a focus on BGP and OSPF, including policy design, traffic engineering, and convergence optimization
• Design and operate modern data center fabrics (spine-leaf architectures, VXLAN/EVPN) with integration into cloud and virtualized environments
• Lead and execute complex network changes and migrations with minimal to zero service disruption
• Serve as a top-tier escalation point, driving issues from initial symptoms to root cause across network, security, and application layers
• Perform deep packet and protocol analysis using tools such as Wireshark and PCAP
• Design and enhance network segmentation, access control, and visibility, leveraging tools like Cisco ISE and Gigamon
• Integrate and support secure access and edge solutions (e.g., Zscaler, Cisco FTD)
• Evaluate existing network environments and recommend improvements for performance, scalability, and operational efficiency

Balance architectural leadership with hands-on engineering and troubleshooting

Required Qualifications

Demonstrated CCIE-level expertise (certification not required)

Extensive experience designing and supporting large-scale enterprise networks

Advanced knowledge of BGP, OSPF, and VXLAN/EVPN architectures

Strong hands-on experience with Cisco platforms (Nexus, Catalyst, NX-OS, IOS-XE)

Proven experience with Network Access Control (NAC) solutions (Cisco ISE or equivalent)

Experience with network visibility tools (Gigamon or similar)

Deep understanding of TCP/IP and packet-level behavior

Ability to troubleshoot complex issues in high-pressure production environments
