Role Summary
Senior specialist responsible for real-time media delivery and network resilience. The role focuses on WebRTC-based streaming quality, end-to-end latency optimization, and robust operation across diverse network conditions.
Key Responsibilities
Design, build, and optimize WebRTC-based media pipelines for interactive video/audio and screen-sharing use cases
Improve quality-of-experience metrics: latency, jitter, packet loss recovery, audio/video sync, start-up time, and stability
Work with real-time protocols and components (RTP/RTCP, STUN/TURN, ICE) and diagnose NAT/firewall traversal issues
Integrate with SFU/media server solutions (e.g., LiveKit or equivalent) and tune server/client configuration for scale
Instrument, profile, and troubleshoot media performance issues across client, edge, and server boundaries
Partner with frontend and backend teams on signalling, session lifecycle, and feature integration
Create diagnostic tooling and reproducible test scenarios for network variability and media regressions
Must-have Skills & Experience
610 years in real-time communication or low-latency streaming systems
Hands-on production experience with WebRTC (client and/or server side)
Strong networking fundamentals and practical debugging (UDP behaviour, NAT, firewalls, packet capture/analysis)
Proficiency in Java with strong debugging skills
Experience profiling and optimizing performance for real-time workloads
Good-to-have / Bonus
Experience with SFU/media server platforms (LiveKit, mediasoup, Janus, Jitsi, Pion, etc.)
Knowledge of codecs and encoder tuning (H.264/H.265/VP8/VP9/AV1; audio codecs)
Experience with observability for media systems (metrics, tracing, QoE dashboards)
Familiarity with adaptive bitrate and congestion control strategies
