The Sensors Division at STR excels at applied research and advanced technology development of impactful sensor system technology to address warfighter and intelligence needs. Our contributions are the culmination of modeling, development, integration, and test and evaluation of new capabilities, with validation testing at each step of development.
The Ocean Technology and Acoustic Systems (OTAS) Group within the Sensors Division executes a broad portfolio of undersea technologies to impact sensing capabilities in contested areas. The Group develops signature exploitations, implements advanced algorithms and processing, and creates new sensing and payload technologies for critical undersea missions. The technologies can be stand-alone or for platforms such as AUVs.
STR is seeking a Mechanical Engineer with experience in the design, fabrication, integration, and testing of subsystems or payloads for unmanned platforms with emphasis on undersea sensors, payloads and vehicles. You will work with teams to realize challenging undersea applications requiring novel and complex engineering solutions. These solutions can only be accomplished by working across multidisciplinary teams to implement and demonstrate them in specific warfighter and intelligence applications.
