Perception Engineer

Sourced from feeny.ai

9 Mothers is hiring a senior Perception Engineer to own the computer vision and machine learning stack powering real-time target detection, classification, and tracking in its counter-drone (counter-sUAS) systems. The role spans model design and training through optimized edge inference on NVIDIA Jetson hardware, plus dataset and simulation pipelines. This is a senior individual contributor position based onsite in Austin, TX.

• Own the visual perception pipeline end-to-end: detection, classification, and tracking of sUAS targets in real time
• Design and train ML models meeting latency and accuracy requirements for edge deployment on Jetson-class hardware
• Architect and maintain the dataset and simulation pipeline, including collection, labeling, augmentation, synthetic data, and closed-loop retraining
• Optimize inference on Jetson via pruning, quantization, TensorRT integration, and custom kernels
• Establish model evaluation frameworks and metrics for operational conditions
• Deliver target state information (position, velocity, identity, uncertainty) to the controls subsystem
• Collaborate with hardware team on camera, optics, and sensor selection

• 6+ years of professional experience in computer vision or machine learning, including production deployment on edge hardware
• Demonstrated experience shipping a detection or tracking system under real-world latency, small-object, or adversarial constraints
• Strong engineering skills beyond modeling, with PyTorch or JAX through to deployed, optimized inference
• Proficiency in Python for model development and C++ or Rust for deployed inference
• U.S. citizenship and ability to pass a background check

• Experience with infrared (IR), thermal, or multi-spectrum camera systems
• TensorRT and NVIDIA Jetson deployment at production scale
• Multi-object tracking under challenging conditions
• Multi-modal sensor fusion (EO/IR, radar, acoustic)
• Synthetic data generation and sim-to-real methodologies
• Prior defense or safety-critical computer vision experience
• Active security clearance or eligibility to obtain one
