About the Team STR's Intelligence Division researches, develops, and transitions advanced analytics and machine-learning solutions for challenging national-security problems. Our team includes engineers and researchers with advanced backgrounds in engineering, computer science, mathematics, and data science who apply deep technical expertise and creativity to mission-critical challenges. Our work spans data analysis, deep learning, and statistical methods across networking, communications, social media, text, time series, geospatial, and imagery data.

We develop capabilities under constraints not typically encountered in commercial environments. U.S. Government analysts use our tools and technologies to extract, enrich, and act on intelligence information worldwide. The Role As a Lead Software Engineer, you will lead the technical execution of mission-relevant software systems that operationalize advanced analytics, machine learning, and data-processing capabilities. You will apply software and systems engineering expertise to develop scalable, secure, maintainable applications that operate in complex customer environments.

You will work with software engineers, systems engineers, researchers, and mission partners to translate customer needs into executable technical plans. You will own technical delivery for an assigned project or major subsystem, guiding architecture, implementation, integration, testing, demonstration, and transition.
