• Strong debugging skills in production environments (packet captures, logs, RTP analysis).

Secondary Skills

• Experience with AI voice systems (STT / TTS / VAD).
• Cloud experience with GCP, Docker, and Kubernetes.
• Familiarity with distributed systems and high-availability architectures.
• Exposure to ACE (C++) framework.

Job Responsibilities

• Design and implement scalable audio/video systems using WebRTC, RTP/RTCP, and WebSocket-based signaling.
• Build and enhance cloud media server/controller components including signaling layer, TURN routing, call control, and media processing.
• Optimize performance for low latency, high throughput, and network resilience.
• Debug and resolve call failures, media negotiation issues, voice quality degradation, jitter, and packet loss.
• Perform root cause analysis (RCA) for production issues.
• Contribute to performance benchmarking and system scalability improvements.

Experience/Education Qualification

• Experience: 5+ years
