Software Engineer

Leidos’ Undersea Systems Division is seeking a Software Engineer in San Diego, CA to join a fast‑paced R&D engineering group. This role is a unique opportunity to drive innovation in underwater vehicle systems, maritime sensors, subsea telemetry, and ISR solutions that support critical defense and national security missions at Naval Information Warfare Center, Pacific (NIWC PAC). Leidos’ USD is a recognized leader in C4

ISR technologies, delivering innovative, mission‑critical solutions across sensor networks, unmanned systems, and tactical platforms. We’re known for achieving “industry firsts” in the most challenging maritime domains. Join us and be part of a world‑class team delivering unmatched solutions for today's most pressing maritime missions.

This individual will work with a small team of engineers and technicians to develop, test, and deliver uncrewed underwater vehicles (UUVs) based on system requirements. Specific development includes software related to operations of UUVs as well as sensor integration. Software Engineering focus:
Develop and refine user interface and control of various sensors integrated onboard UUVs. Develop and optimize UUV behaviors to accomplish assigned tasks while maximizing opportunities for sensor data collection. Optimize existing code (C/C++/C#, Java and Python). Develop platform‑independent data processing tools. Produce SW performance reports based on test & evaluation requirements. Create engineering & training documentation for technological deliveries. Architect and implement secure CI/CD pipelines utilizing modern containerization and Dev Ops principles, integrating automated testing and vulnerability scanning to accelerate deployment cycles while maintaining high code quality.

Testing involves working onboard small boats and ships on the ocean, launching and recovering systems at sea, and post‑test analysis of data. Reporting includes providing results from post‑test data analysis into official reports or briefing material. Most development and testing will be conducted in San Diego; however, engineers may occasionally travel in support of testing, training and/or operations in other locations both in the U.S. and abroad and may spend multiple days at‑sea onboard ships.

In addition to primary duties, this individual will be encouraged to develop expertise on the functionality and operations of one or more UUV platforms, new technologies, and may be asked to operate the system at‑sea during test and evaluation.
