Software Engineer C++ VoIP offline onboarding in Tashkent (2–3 months)

We build cloud telephony for business — from small teams to call centers. Our platform works without hardware, integrates incoming and outgoing communications, and is used by thousands of companies. Under the hood, it's our own VoIP solution on a Windows stack, which we build and develop in-house.

What you will do

Develop and maintain our own VoIP engine — server and client telephony components. Real tasks: performance optimization, voice traffic quality, integration with telephony gateways and carrier APIs. Participation in code reviews and architectural decisions — not a formality, but part of the job.
