Perception Engineer

The role

The Perception Engineer will own the computer vision and machine learning stack for counter-sUAS systems. This senior individual contributor will research, develop, and deploy a perception pipeline to enable real-time engagement of aerial threats.

What you will do

• Own the visual perception pipeline end-to-end including detection, classification, and tracking of sUAS targets in real time.
• Design and train machine learning models for edge deployment on Jetson-class hardware.
• Architect and maintain the dataset and simulation pipeline.
• Optimize inference performance on Jetson platforms.
• Establish the model evaluation framework and metrics.
• Deliver target state information to the controls subsystem.
• Collaborate with the hardware team on camera, optics, and sensor selection.

Required qualifications

• 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 including experience with PyTorch or JAX through to deployed, optimized inference.
• Proficiency in Python for model development.
• Proficiency in C++ or Rust for deployed inference.
• U.S. citizenship.
• Ability to pass a background check.

Nice to have

• Experience working with infrared (IR), thermal, or multi-spectrum camera systems.
• TensorRT and NVIDIA Jetson deployment experience at production scale.
• Multi-object tracking under challenging conditions.
• Multi-modal sensor fusion experience (EO/IR, radar, acoustic).
• Synthetic data generation and sim-to-real methodologies.
• Prior experience in defense or other safety-critical computer vision applications.
• Active security clearance, or eligibility to obtain one.
• A passion for building robots or engineering projects as a hobby.
