The company is building autonomous machines for defense markets and needs a Lead/Principal AI Engineer to design, develop, and deploy low-latency machine learning models for real-time detection, tracking, and classification of hostile FPV suicide drones.

Requirements

  • Non-negotiable proficiency in Python.
  • Extensive experience with deep learning frameworks such as PyTorch and TensorFlow.
  • Deep understanding of classification models, neural network architectures, and demonstrated experience with sensor fusion.
  • Practical experience with the entire machine learning lifecycle, including model optimization for edge deployment and resource-constrained environments.
  • Strong knowledge of linear algebra, calculus, and statistics necessary for debugging, optimizing, and writing core machine learning algorithms.

Responsibilities

  • Design, train, and optimize novel neural network architectures specifically for rapid threat classification (e.g., differentiating hostile drones from environmental clutter).
  • Implement robust sensor fusion techniques to combine and interpret disparate data streams (radar, RF, acoustic, and optical sensors).
  • Drive MLOps and edge deployment strategies, ensuring machine learning models are efficiently deployed, monitored, and updated in the field on low-SWaP hardware.
  • Apply advanced machine learning techniques, particularly anomaly detection (AD), to ensure the system can adapt to and identify new, custom-built drone threats not present in the training data.
  • Collaborate with the robotics and computer vision teams to ensure model output seamlessly translates into real-time trajectory predictions for interceptor guidance.

Other

  • Must be willing to submit to a background check.
  • Compliance: This position requires access to export-controlled information under ITAR. Only U.S. persons are permitted to access such information.
  • Security clearance or ability to obtain one
  • Prior defense startup experience
  • Passion for building robots or engineering projects as a hobby
