Lead VoIP / Unified Communications Engineer

Chicago, IL – Onsite

Base Salary: $150K–$160K

No Remote

No Sponsorship offered

I’m conducting a confidential search for a Lead VoIP / Unified Communications Engineer to join a highly respected, mission-driven organization in Chicago that is making a significant investment in modernizing its technology infrastructure.

This is much more than a VoIP support role.

We are looking for a senior-level voice engineer who can remain technically hands-on while becoming a trusted technical leader and right hand to infrastructure leadership .

The environment includes enterprise voice, VoIP PBX, SIP trunking, Call Center technologies, e911, eFax, voicemail and the underlying network infrastructure required to deliver highly available voice services.

What You'll Do:

  • Lead the design, implementation and support of enterprise voice infrastructure
  • Serve as the technical escalation point for complex VoIP and telecommunications issues
  • Support VoIP PBX, SIP trunking and Contact Center technologies
  • Lead complex voice and infrastructure projects
  • Mentor and provide technical direction to other engineers
  • Work closely with vendors and internal technology teams
  • Help establish technical standards and procedures
  • Monitor and improve voice infrastructure performance and reliability
  • Participate in the continued modernization of a large enterprise infrastructure environment

Ideal Background:

  • 5+ years of enterprise VoIP/voice engineering experience
  • Strong Avaya or comparable enterprise voice technology
  • VoIP PBX and SIP trunking expertise
  • Contact Center / Call Center experience
  • Strong understanding of networking and QoS
  • Experience supporting large, complex, mission-critical environments
  • Technical leadership or mentoring experience
  • Healthcare experience is helpful but not required
  • Cisco knowledge is highly desirable

The right person will be someone who enjoys being in the weeds technically but also wants greater leadership visibility and influence .

This is an onsite Chicago opportunity with a long-term opportunity to play an important role in a significant infrastructure transformation.

Please message me directly if you'd like to learn more or know someone who could be a fit.
