About this role
Rocket Lab Optical Systems solves mission-critical space domain and Intelligence, Surveillance, and Reconnaissance challenges for Department of Defense and Intelligence Community customers. Our vision is to revolutionize the space-based payload market with innovative and novel designs for space, terrestrial, and airborne environments.
Building on more than 20 years of electro-optical and infrared systems innovation from Geost, Rocket Lab Optical Systems delivers solutions to the warfighter for responsive, scalable sensing solutions across all orbital domains. As Principal Machine Learning Engineer for Rocket Lab Optical Systems in Tucson, AZ, you will have the opportunity to support Tranche 3 of the U.S.
Space Development Agency's (SDA) Proliferated Warfighter Space Architecture (PWSA) and beyond by building deep learning neural networks for advanced Electro-Optical (EO/IR) image processing.
WHAT YOU’LL DO
- Develop computer vision algorithms and deep neural networks for image and video processing chains.
- Collaborate with other researchers/engineers on artificial intelligence, machine learning, and computer vision.
- Work with physics-based image simulation frameworks to scale training and validation data.
- Design, train, and deploy machine learning models for Optical Systems applications.
- Preform rapid prototyping and enhanced development to be integrated into operational systems.
- Perform troubleshooting, bug fixes, and maintenance of existing and new systems.
- Stay current with ML research and evaluate new tools, frameworks, and techniques.
