Job Summary

Own hardware-accelerated video pipelines on ARM-based SoC platforms — encode, decode, transcode and streaming paths built on GStreamer and vendor codec interfaces, for multi-stream edge and enterprise devices.

Key Responsibilities

- Design, build and optimize GStreamer pipelines for hardware-accelerated encode, decode, transcode and composition.
- Integrate and maintain codec plugins and V4L2 stateful/stateless codec interfaces for H.264, H.265, VP9 and AV1 as supported by the platform.
- Enable multi-stream, multi-resolution concurrency with defined latency, bitrate and throughput targets.
- Implement zero-copy buffer flows between camera, video, GPU, display and inference stages.
- Build and tune low-latency streaming paths (RTSP/RTP/WebRTC class) and container/muxing handling.
- Profile and resolve pipeline stalls, dropped frames, A/V sync drift, latency spikes and memory bandwidth bottlenecks.
- Develop custom GStreamer elements and plugins where platform capability is not covered upstream.
- Define video KPI measurement methodology and contribute to automated video regression suites

Skill Requirements





- 8–10 years in embedded multimedia / video software engineering.
- Expert-level GStreamer — pipeline design, element and plugin development, negotiation, caps, queues, debugging with GST_DEBUG and pipeline graphs.
- Strong C/C++ on embedded Linux.
- Hardware codec integration experience via V4L2 codec APIs or vendor codec SDKs.
- Solid grasp of video compression fundamentals — GOP structures, rate control, profiles/levels, bitstream basics for H.264/H.265.
- Zero-copy buffer management (dma-buf / DMA heaps) and memory bandwidth awareness.
- Performance profiling and latency measurement on constrained SoC platforms
