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
