Software Engineer Intern

Leidos is currently seeking a Software Engineer Intern for Summer 2025. The position is located in Arlington (Ballston), VA.

We are seeking a college technical intern to be part of a team of engineers addressing emerging challenges in Maritime Systems. The candidate will be assigned tasks that are relevant and necessary to the successful execution of Leidos contracts. Leidos will provide the candidate with real world experience and technical and career mentorship throughout the internship, which may result in full-time employment opportunities upon graduation.

Last year’s interns supported real testing as part of an integrated test team, wrote user interface and simulation software that is in use today, and supported our cybersecurity strategy. In addition to these kinds of tasks, other work assignments, depending on ability and interest, may include developing algorithms and computer models, supporting the software design of autonomous vehicles, performing model runs, benchmarking hardware performance, building user interfaces, tuning radar/optical systems, and performing sea test data analysis.

The position may require paid travel to either our integration facility in Long Beach, MS, or to test facilities in the Virginia Beach, VA or San Diego, CA, areas.
