Network Engineer

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

· 6–10 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 at least one of: C/C++, JavaScript/TypeScript, Go, or Rust, 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
