Tech Lead Cloud Call Controller

We are looking for a Technical Lead who will drive the technical architecture , design and development of cloud media server and controller systems. S trong skills in C/C++, networking protocols, real-time media systems, WebRTC, RTP/RTCP, and WebSockets Basic Requirements We are looking for a Technical Lead who will drive the technical architecture , design and development of cloud media server and controller systems. Primary Skills Expertise in C/C++ systems programming, including concurrency models, memory optimization, and network stack tuning. Production experience with: UDP / TCP, RTP / RTCP timing models, ICE / STUN / TURN at scale, and NAT traversal strategies. Strong architectural knowledge of WebRTC internals, SIP / VoIP signaling flows, SFU/MCU design patterns, jitter buffer algorithms, and latency optimization techniques. Hands-on experience leading deployments of open-source RTC stacks such as LiveKit, Janus, or similar WebRTC platforms. Strong skills in performance profiling, scalability engineering, and production-grade debugging. Secondary Skills Experience integrating AI voice systems (STT / TTS / VAD) into RTC pipelines. Strong cloud architecture experience (GCP, Docker, Kubernetes, multi-region failover). Solid understanding of distributed systems, high-availability design, and observability frameworks. Familiarity with ACE (C++) framework. Job Responsibilities Own the architecture and development of cloud media server and call controller software. Design scalable signaling infrastructure, TURN routing strategies, and media routing topologies for high volume concurrent sessions. Define performance and latency optimization strategies across modules. Lead debugging and resolution of complex production issues involving call failures, QoS degradation, congestion, and scaling bottlenecks. Establish engineering standards for reliability, observability, and performance benchmarking. Mentor engineers, conduct design reviews, and guide architectural decisions. Drive continuous improvements in scalability, resilience, and operational excellence. Experience/Education Qualification Experience: 8+ years Bachelor s degree in computer science, Electronics & Communication, Electrical Engineering, Information Technology, or a related technical discipline (Optional but preferred) Master s degree (M.Tech/M.S/MCA.) in a relevant field is a plus.
