Position Summary

We are seeking a highly skilled and resourceful Unified Voice & Firewall Engineer to join our team. This is a critical role for our client who can expertly bridge the gap between our enterprise voice collaboration systems and our network firewall security. You will be a key player in ensuring secure, reliable systems. This is a unique, long-term opportunity for a hands-on engineer who thrives in a dynamic, cross-functional environment. While the ideal candidate will have extensive experience, we are open to strong candidates with a passion for excellence and a proven track record of success. We are also open to considering two separate resources for the voice and firewall aspects of this role.

  • Administer and support Cisco Unified Communications Manager (CUCM), Webex Calling, and Webex Contact Center.

  • Manage and maintain voice recording platforms (Cistera or similar).

  • Oversee the entire certificate lifecycle, including deployment, renewal, and securing certificates for voice systems.

  • Monitor voice system performance using tools such as LogicMonitor, WhatsUp Gold, or SolarWinds to ensure optimal quality of service and uptime.

  • Network Firewall Security:

  • Configure, administer, and maintain enterprise firewalls, with a primary focus on Cisco ASA/FTD and Fortinet FortiGate .

  • Implement robust firewall policies, Virtual Private Networks (VPNs), Network Address Translation (NAT), and Access Control Lists (ACLs) to secure the universitys network.

  • Proactively identify and address security vulnerabilities and risks.

  • Cross-Functional Engineering:

  • Serve as the primary point of contact for troubleshooting complex issues that span both the voice and security domains.

  • Collaborate with other IT teams to ensure voice and network systems are integrated seamlessly and securely.

  • Maintain detailed documentation of configurations, procedures, and troubleshooting steps.

Required Skills & Qualifications
  • Experience: Hands-on experience in both Voice/Unified Communications engineering and Firewall administration. While 6 years of experience is preferred, we value expertise and demonstrated capability over a specific number of years.

  • Voice/UC Expertise:

  • Strong hands-on knowledge of Cisco CUCM, Webex Calling, Webex Contact Center, and SIP trunks.

  • Proven experience with voice system integration.

  • Proficiency with voice recording platforms.

  • Network Security Expertise:

  • Expertise in Cisco ASA/FTD and Fortinet FortiGate administration is a must.

  • Experience with Palo Alto firewalls is a strong plus.

  • In-depth knowledge of firewall policies, VPNs, NAT, and ACLs.

  • Certifications:

  • Relevant industry certifications such as CCNP Collaboration, CCNP Security, Fortinet NSE, or PCNSE are highly preferred.

  • Monitoring & Tools:

  • Familiarity with network and performance monitoring tools like WhatsUp Gold, LogicMonitor, or SolarWinds.
