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
