You'll play a key role in supporting and maintaining business-critical voice systems, whilst developing your exposure to LAN, WAN, firewalls and wider network infrastructure.

• Support and administer Cisco Unified Communications Manager (CUCM), Cisco Unity and Microsoft Teams environments.
• Investigate and resolve complex voice-related incidents, ensuring minimal disruption to critical services.
• Support SIP connectivity, call routing and wider voice networking technologies.
• Work alongside experienced network engineers to develop your understanding of LAN, WAN, routing, switching and firewall technologies.

• Participate in BAU activities, infrastructure upgrades and technical improvement projects.
• Collaborate with internal teams and third-party suppliers to troubleshoot and resolve technical issues.
• Participate in an on-call rota, providing support for critical incidents across the wider network estate.

Essential Experience:

• Strong hands-on experience with Cisco Call Manager (CUCM) and Cisco Unity.
• Experience supporting Microsoft Teams and unified communications environments.
• Good understanding of SIP, VoIP and voice networking technologies.
• Experience troubleshooting complex voice infrastructure issues.

What Makes Someone Successful Here?
Our client is looking for someone who is naturally inquisitive, enjoys understanding how technologies work and isn't afraid to ask why.
You'll thrive in this environment if you:

• Are comfortable working across different technologies and learning from colleagues.
• Communicate clearly and enjoy contributing to a collaborative team.
• Want to continue developing your technical expertise beyond your core specialism.

Why Join?
