Muxers/demuxers (MP4, MKV, PS/TS, etc.)

AI inference pipelines with NPU/GPU acceleration

Zero-copy pipelines (Camera → GPU → NPU → Display)

Optimize pipelines for latency, throughput, CPU/GPU/NPU utilization, power efficiency, and memory footprint.Debug system-level multimedia issues involving drivers, HAL, middleware, and user-space frameworks.Work closely with hardware and firmware teams to enable new platform features and bring up next-generation SoCs.Contribute to architecture design, code review, documentation, and continuous integration.

Minimum Qualifications
