Role Summary
The Media Pipeline Engineer is responsible for designing, implementing, and stabilizing real‑time audio/video processing pipelines for our product. This role focuses on SDI capture and playout, file playout, encoding/decoding, transcoding, up/down conversion, logo insertion, and preview stream generation using open‑source media frameworks. The engineer will build and optimize long‑running, low‑latency media pipelines and integrate them with the product control plane and web application.

Key Responsibilities

Design real‑time media pipelines using GStreamer and/or FFmpeg.

Implement SDI capture and SDI playout using vendor SDKs and Linux drivers.

Build pipelines for:

File → SDI

File → SDI-4K

SDI-3G → H.264 stream

SDI-3G → SDI-4K

H.265 stream → SDI-3G

SDI → SDI with logo insertion

Implement low‑bitrate proxy preview pipelines for UI monitoring.

Optimize pipelines for low latency and stable long‑duration operation.

Implement audio handling and synchronization.

Integrate GPU acceleration (NVDEC/NVENC, VAAPI, QSV) where applicable.

Expose pipeline lifecycle controls (start, stop, restart, status).

Collect and report runtime metrics:

Bitrate

Frame drops

Buffer levels

CPU/GPU utilization

Troubleshoot SDI signal issues, format mismatches, and clocking problems.

Collaborate with backend engineers to integrate control APIs.

Participate in system‑level testing and demo validation.

Required Skills & Experience

Strong Linux systems programming background.

5+ years working with FFmpeg and/or GStreamer.

Experience integrating professional SDI I/O hardware (Deck Link, AJA, or similar).

Solid understanding of:

SDI formats (3G, 12G, UHD)

Interlaced vs progressive video

Frame rates and timebase

Color spaces (BT.709, BT.2020)

Experience with H.264 and H.265 encoding/decoding.

Experience with real‑time streaming protocols (SRT, RTP, UDP).

Debugging using ffprobe, gst-launch, Wireshark.

Preferred Qualifications

Experience building broadcast appliances or master‑control systems.

Familiarity with WebRTC or HLS preview pipelines.

GPU acceleration experience.

Experience building long‑running daemons/services.
