Cisco Identity Services Engine (ISE) Lead to provide senior engineering, operations, and technical leadership for enterprise network access control. The successful candidate will lead the development, testing, implementation, and sustainment of Cisco ISE policies that enforce Comply-to-Connect (C2C) requirements across wired, remote-access, and network-device-administration environments.
The ECS3 program supports our intelligence customer across CONUS and OCONUS locations through the design, transition, operations, modernization, technology refresh, and continual improvement of enterprise LAN, Unified Communications, and cybersecurity services. The Tier 3 ISE Lead will work with network, cybersecurity, endpoint-management, and identity teams to translate approved access-control requirements into scalable, supportable ISE policy and operational capabilities.
Responsibilities: Lead ISE and C2C policy engineering Design, create, test, implement, document, and sustain ISE authentication and authorization policies, authorization profiles, identity source sequences, endpoint groups, profiling rules, posture policies, and exception workflows.
Implement enterprise access-control methods Engineer and support 802.1X, EAP-TLS, MAB, RADIUS, TACACS+, guest access, contractor access, certificate-based authentication, and network-device administration.
Develop C2C enforcement and remediation workflows Implement policy actions using dynamic VLAN assignment, downloadable ACLs, Security Group Tags, Change of Authorization, reauthentication, restricted-access controls, quarantine actions, and endpoint-remediation workflows.
Lead ISE integrations Integrate and sustain ISE connections with Active Directory, PKI and certificate authorities, endpoint-management tools, endpoint-security platforms, vulnerability-management tools, SIEMs, pxGrid clients, switches, VPN infrastructure, and other approved security services.
Provide Tier 3 troubleshooting and incident support Resolve complex authentication, authorization, certificate, profiling, posture, endpoint, CoA, RADIUS, TACACS+, and network-device issues. Analyze ISE Live Logs, session traces, alarms, packet captures, switch logs, support bundles, and endpoint data to determine root cause and corrective actions.
Maintain ISE platform health and resiliency Administer and troubleshoot the distributed ISE deployment, including PAN, secondary Administration node, PSNs, MnT, pxGrid, node groups, replication, backups, restores, certificates, performance, capacity, and disaster-recovery procedures.
Plan and execute lifecycle activities Support ISE upgrades, patches, certificate renewals, policy migrations, technology refresh, node recovery, backup validation, and approved maintenance activities. Develop implementation, test, validation, rollback, and post-change review plans.
Establish technical standards and change controls Develop and maintain policy naming standards, configuration baselines, test procedures, implementation checklists, rollback procedures, SOPs, and knowledge articles. Review proposed policy changes for operational impact, dependencies, and access risk.
Lead C2C onboarding and operational improvement Support pilot efforts, site onboarding, phased rollout, transition to operations, recurring-incident reduction, and continuous improvement of C2C policy and service delivery.
Provide technical leadership and escalation management Mentor teammates; provide technical guidance to engineering and operations teams; coordinate Cisco TAC cases; and produce complete escalation packages, root-cause analyses, and after-action reports.
