Computer Vision Engineer

Zillion Technologies, Inc.; Virginia (IL); Hybrid; USD 120,000 - 150,000; Full time

Job summary

Zillion Technologies, Inc. is hiring a Computer Vision Engineer for a hybrid role in Ashburn, VA or Bethesda, MD. You will own computer vision engineering efforts, building edge-deployed pipelines on NVIDIA Jetson hardware and GPU servers to operate in real-world spaces.

You will build systems for person and intent detection, multi-camera tracking, and track packaging events at shelf zones. You will also create training and deployment pipelines and optimize edge performance for robust inference.

Qualifications

• 5+ years of hands-on computer vision engineering experience, with at least 2 years deploying models to production edge hardware (not just cloud or research environments)
• Deep practical experience with the YOLO family of detectors - training, fine-tuning, hyperparameter tuning, and understanding failure modes in real-world conditions
• Proficiency with PyTorch for model training and ONNX / TensorRT for inference optimization; hands-on experience with INT8 or FP16 post-training quantization
• Experience building multi-object tracking pipelines - SORT, DeepSORT, BoT-SORT, or equivalent - and understanding the tradeoffs between tracker accuracy, computational cost, and track stability
• Solid Python and C++ skills for pipeline development; comfort reading and modifying GStreamer pipeline graphs
• Experience with NVIDIA GPU tooling: CUDA, cuDNN, TensorRT, and the JetPack / Jetson SDK ecosystem
• Experience building annotation pipelines and managing training datasets for custom object detection tasks - not just using pre-trained models on standard benchmarks
• Comfort working with RTSP IP camera streams in Linux environments; understanding of H.264/H.265 codec pipeline and hardware decode
• Experience with cross-camera person re-identification - OSNet, FastReID, or equivalent architectures; homography-based multi-camera fusion
• Experience with zone-based spatial analytics - polygon intersection, floor-plane projection, homography calibration from camera to world coordinates

Responsibilities

• Own computer vision engineering efforts across edge devices and GPU servers.
• Build and optimize CV pipelines for edge deployment on NVIDIA Jetson hardware.
• Develop systems for person and intent detection, and multi-camera tracking.
• Create model training and deployment pipelines and perform edge deployment and performance optimization.

Job description

Role: Computer Vision Engineer

Type of Employment : Full time with Zillion Technologies

Location: Ashburn, VA or Bethesda MD (Hybrid)

The Computer Vision Engineer role owns all computer vision engineering effort. You will work on edge-deployed CV pipelines running on NVIDIA Jetson hardware, and GPU servers - building, training, optimizing, and deploying models that handle real-world conditions in public and commercial spaces.

You will build systems with person and intent detection, multi-camera tracking, track package placement and removal events at shelf zones. You will also build model training and deployment pipelines and perform edge deployment and performance optimization.

Required

• 5+ years of hands-on computer vision engineering experience, with at least 2 years deploying models to production edge hardware (not just cloud or research environments)
• Deep practical experience with the YOLO family of detectors - training, fine-tuning, hyperparameter tuning, and understanding failure modes in real-world conditions
• Proficiency with PyTorch for model training and ONNX / TensorRT for inference optimization; hands-on experience with INT8 or FP16 post-training quantization
• Experience building multi-object tracking pipelines - SORT, DeepSORT, BoT-SORT, or equivalent - and understanding the tradeoffs between tracker accuracy, computational cost, and track stability
• Solid Python and C++ skills for pipeline development; comfort reading and modifying GStreamer pipeline graphs
• Experience with NVIDIA GPU tooling: CUDA, cuDNN, TensorRT, and the JetPack / Jetson SDK ecosystem
• Experience building annotation pipelines and managing training datasets for custom object detection tasks - not just using pre-trained models on standard benchmarks
• Comfort working with RTSP IP camera streams in Linux environments; understanding of H.264/H.265 codec pipeline and hardware decode
• Experience with cross-camera person re-identification - OSNet, FastReID, or equivalent architectures; homography-based multi-camera fusion
• Experience with zone-based spatial analytics - polygon intersection, floor-plane projection, homography calibration from camera to world coordinates

Strongly preferred

• Experience building CV systems for retail, logistics, or security environments where the camera network covers a physical space and detections must be spatially anchored
• Familiarity with Roboflow or CVAT for dataset management and annotation workflow automation
• Experience with the NVIDIA Metropolis or DeepStream framework - even if ultimately not used, understanding where these add value vs a custom open-source stack
• Prior work on privacy-preserving CV pipelines - on-device inference, derived-data-only architectures, anonymization techniques
