Senior Computer Vision & Video Inference Engineer (DeepStream / TensorRT / GStreamer)

We are seeking a Senior Computer Vision & Video Inference Engineer to audit, optimize, and stabilize a real-time, multi-stream video analytics pipeline. The core focus of this engagement is strictly the computer vision and edge/GPU inference layer—optimizing detection, multi-object tracking, hardware-accelerated video decoding, and GPU throughput across concurrent RTSP feeds. You will work alongside our core engineering team to harden the pipeline for long-running reliability and integrate metadata outputs into our existing backend services. Key Responsibilities - Audit and tune Ultralytics YOLO models (v8+) using TensorRT FP16/INT8 quantization for production deployment. - Refine multi-object tracking (ByteTrack) to minimize ID switches, trajectory fragmentation, and false boundary crossings using spatial heuristics (confirmation frames, hysteresis, dead zones). - Harden RTSP stream ingestion, decoding, and watchdog recovery using GStreamer and OpenCV to eliminate backpressure and dropped frames. - Profile and scale inference throughput using NVIDIA DeepStream (nvstreammux, nvinfer, nvtracker) on discrete GPUs and/or Jetson targets. - Identify and eliminate memory leaks, thread contention, and CPU-GPU transfer bottlenecks using Linux/CUDA profiling tools (e.g., Nsight Systems). - Expose telemetry metrics (FPS, stream health, latency) and bridge metadata via ZeroMQ, REST, or lightweight IPC. Required Qualifications - Proven track record deploying production video pipelines with NVIDIA DeepStream SDK, TensorRT, and CUDA. - Deep hands-on experience with GStreamer pipeline construction, RTSP protocols, and hardware decoding. - Strong practical background with YOLO architectures, ByteTrack (or similar MOT algorithms), and boundary/line-crossing analytics. - Advanced concurrent Python (multiprocessing, async, queues) with strong Linux systems debugging. - Experience writing or configuring custom C++ parsers/plugins for DeepStream is a strong plus.
