564 | Senior C/C++ with Telecommunications Knowledge (2 months project)

We are working on a healthcare product — we developed from scratch a multilayer, web-based platform, built on the basis of microservice architecture which supports numerous integrations with external web services and third-party applications.

Programming Languages

• C/C++: Proficiency in C or C++ is essential, as FreeSWITCH is primarily written in these languages.
• (Optional) Lua: Familiarity with Lua for scripting within FreeSWITCH applications.

Telecommunications Knowledge

• SIP (Session Initiation Protocol): Understanding SIP signaling, which is fundamental for VoIP communications.
• (Optional) VoIP Concepts: Familiarity with Voice over IP technologies and protocols.

FreeSWITCH Framework

• Module Development: Experience in developing and integrating custom modules within the FreeSWITCH framework.

Networking

• TCP/IP: Understanding of networking concepts, including IP addressing, routing, and firewall configurations.
• Experience with TCP sockets and network streams

Operating Systems

• Linux/Unix Proficiency: skills in Linux/Unix environments where FreeSWITCH typically runs.

Audio Encoding

• Understanding of various audio codecs (e.g., G.711, G.729, Opus).
• Knowledge of audio encoding/decoding processes and transcoding techniques.
