We are seeking a skilled Andriod Audio and Video SDK Developer to design and optimize cutting-edge real-time communication solutions. You will play a key role in enhancing our audio/video SDK and client applications, ensuring top-tier performance, reliability, and user experience.

Job Responsibilities:

Develop and optimize WebRTC-based SDKs, focusing on:

• Capture/rendering optimization, signaling/media protocols, codecs (H.264/Opus), AEC, and QoS (latency/fluency/bitrate adaptation).
• Key modules: congestion control, ULPFEC/FLEXFEC, jitter buffer, NACK, NetEQ, and STUN/TURN/ICE (RFC 5245).

Maintain and improve existing AV SDKs/clients to enhance performance (e.g., delay reduction, smoothness, video quality).

Research and integrate emerging WebRTC/streaming technologies into production.

Job Requirements:

Bachelor's degree or higher with 2+ years of C/C++ development experience.

Deep expertise in WebRTC native code:

• Customization/optimization of AV pipelines, jitter buffer, rate adaptation, and familiarity with Opus/H.264/H.265.
• Strong grasp of RTP/RTCP, ICE, STUN, TURN, and P2P networking.

Proficient in WebSocket, UDP/TCP/IP, HTTP, and tools like Wireshark/Charles/Fiddler.

Experience with FFmpeg, GStreamer, Janus, or similar open-source projects is a plus.

Prior work in end-to-end AV systems (capture, encode, streaming, playback) and WebRTC QoS tuning preferred.

Strong problem-solving skills, teamwork, and a passion for real-time multimedia technologies.
