Responsibilities

• Lead the full lifecycle of Cisco ISE wired NAC deployment, including design, build, piloting, and phased production rollout across all branch locations.
• Develop and standardize access switch configurations (IOS/IOS-XE), integrating key security features like 802.1X, MAB, and downloadable ACLs.
• Integrate the NAC solution with external identity sources, including Active Directory, Public Key Infrastructure (PKI), and AAA services (RADIUS/TACACS+).

Required Qualifications

• 5+ years of professional experience in enterprise-level routing and switching technologies (e.g., OSPF, BGP, HSRP/VRRP, LACP).
• Demonstrable experience implementing Cisco ISE wired access control (802.1X/MAB/EAP-TLS) in a production environment of 500+ users.
• Strong practical knowledge of RADIUS/AAA, campus security controls (DHCP snooping, DAI), and endpoint onboarding troubleshooting.
• Proficiency in creating high-quality technical documentation, including Methods of Procedure (MOPs), runbooks, and rollback plans.

This contract role offers the chance to drive a critical security upgrade, leveraging your expert-level skills in Cisco networking and NAC to secure a large enterprise infrastructure.
