Help build software that turns complex sensor data into information people can understand and act on. Our teams develop software for radar and command-and-control systems, with opportunities spanning backend services, data processing, and full-stack web applications.

As a Software Engineering Intern, you will work alongside experienced engineers to solve practical problems and contribute to software used in demanding environments. Depending on your assigned project, you may develop a service, build an interactive interface, improve system performance, or automate testing.

→Build useful software: Design, code, test, integrate, and document new capabilities and improvements to existing applications.
→Connect data to decisions: Contribute to software that processes information, connects services, or presents complex data through web interfaces and visualizations.
→Solve a defined engineering challenge: Translate requirements into an implementation, explore technical tradeoffs, and deliver work with clear scope and expectations.
→Collaborate across disciplines: Work with software and systems engineers to understand how your contributions fit into the larger system.
→Learn through feedback: Participate in design discussions, code reviews, and demonstrations to strengthen your engineering judgment and communication skills.
→Develop professional engineering habits: Use version control, automated testing, debugging, and established development processes to produce reliable, maintainable software.
→U.S. citizenship is required.

→Modern software tools and practices: Gain hands-on experience with development tools, automated testing, and workflows used to build reliable software.
→How complex systems fit together: Learn how software architecture connects sensors, backend services, and user interfaces in radar and command-and-control systems.
→Engineering tradeoffs: Understand how teams balance performance, reliability, security, and maintainability—and how those decisions support broader technical strategy.
→Emerging technologies: Explore advances in software development, radar, and command-and-control systems, and evaluate how they could improve your project.
