Crexendo operates a hosted unified communications platform (VoIP, SIP, FreeSWITCH, OpenSIPS) serving over six million end users globally. The tech stack reveals a traditional telecom infrastructure foundation — Linux, SIP signaling, open-source switching — combined with Microsoft Office tooling and TestRail for QA. Hiring momentum centers on sales (3 roles) with lighter engineering lift, consistent with a maturing platform focused on customer onboarding and adoption rather than core infrastructure rebuilds.
