- Drive automation and scalability by integrating Infrastructure as Code (IaC) practices using Python, Ansible, and API integrations to streamline NAC deployments and policy enforcement at enterprise scale.
- Ensure network reliability and compliance through proactive monitoring, certificate management, performance troubleshooting, root‑cause analysis, and documentation via ServiceNow.
- Lead and collaborate on network projects, develop design documentation, implementation plans, and support new solution rollouts, upgrades, and cross‑functional stakeholder communications.

What Do You Need to Have?
- Bachelor's degree in a technology‑related field or equivalent combination of education and hands‑on experience.
- Proven experience deploying and supporting Cisco ISE in large enterprise environments, including building rules, policies, and ISE solutions across diverse infrastructures.
