• Strong experience with Juniper, HPE, and Palo Alto technologies.
• Working knowledge of Network Access Control (NAC) solutions.
• Understanding of change control processes and technical documentation.
• Up-to-date networking accreditations (Juniper, Aruba, or equivalent).
• Excellent communication and stakeholder engagement skills.

Desirable:
