New York, New York, United States Lumicity Full time

Senior Video Infrastructure Engineer

We're building real-time ML systems that operate directly in live broadcast workflows. Our software ingests live streams from broadcasters (e.g. sports events), processes them in real time (including copyright audio removal), and returns broadcast-quality streams with ultra-low latency.

This role owns the
live video infrastructure
that makes this possible.

What You'll Do

  • Build and operate
    SRT-based live video ingest and output pipelines
  • Use
    FFmpeg
    to decode, process, and re-encode broadcast-quality video and audio in real time
  • Integrate real-time ML inference into live video streams with strict latency budgets
  • Tune pipelines for
    low latency, reliability, and long-running stability
  • Work with live protocols including
    SRT, RTMP, RTP/RTSP, MPEG-TS
  • Collaborate closely with ML engineers on production inference systems

What We're Looking For

Required

  • 5+ years experience with
    live video or broadcast systems
  • Deep, production experience with FFmpeg
    (required; core dependency)
  • Hands-on experience running
    SRT-based live video pipelines
  • Strong understanding of codecs, containers, and A/V sync in live environments
  • Systems programming experience (Python, C/C++, Rust, or similar)

Nice to Have

  • GStreamer or similar media pipeline frameworks
  • Broadcast or live sports streaming experience
  • GPU-accelerated video pipelines (NVENC, VAAPI, CUDA)
  • Experience operating media systems in cloud environments

Why This Role

  • Own mission-critical live video infrastructure
  • Work at the intersection of
    broadcast video and real-time ML
  • High autonomy, real production impact
