Engineer for Video Communications Systems (VCS-SE) responsible for designing, developing and testing the Media System framework and Media Systems for VoIP / Video Communications. The overall scope also involves integrating and testing audio / video processing components such as speech and video codecs, design, develop and test QoS features of VoIP / VC applications such as Jitter management, AEC/ANR, VAD/CNG, etc. Responsibility also includes development of end applications including integrating signaling protocols such as SIP / H.323 as well as designing, developing and testing of the user agent, GUI and the system state machine.

The job profile includes, but not limited to,

1. Development of IPs for VCS such as Adaptive Jitter Buffer, CPT, DTMF, VAD / CNG, Dynamic Bandwidth Adaptation for various network conditions, etc
2. Integration of speech and video codecs and components (like AEC / ANR / Resampler, etc)
3. Development, integration and testing of protocols such as RTP, RTCP, SRTP etc
4. Development, integration and testing of signalling user agents for SIP, H.323
5. Analysis of media signal pipeline on different SDKs, platforms for optimizations and effeciency
6. Working with internal teams and customers to understand requirements and technology and develop solutions.
7. Ensuring all of functionality, performance, and reliability of VCS applications on target platforms
