Job Description

Leidos’ High Fidelity Simulation Business Area designs and delivers cutting‑edge system‑of‑systems solutions that power world‑class simulation, training, and analysis products for the U.S. Navy.

In this role, based at a U.S. Government facility in Bethesda, MD, your primary focus will be on developing and maintaining server‑side components for a web‑based Learning Management System (LMS). You will support the evolution of a mature and widely used platform by enhancing backend modules, improving system reliability, and implementing new features in collaboration with Navy partners.

When program needs and funding align, you may also have opportunities to contribute to other Tactical Signature Guidance (TSG) systems-providing exposure to state‑of‑the‑art technologies that directly support the development of advanced sonar tactical decision aids (TDAs).

At Leidos, we empower our engineers to do meaningful work while continually building new skills to grow the career they want to achieve.

What You’ll Work On

• Develop and enhance server‑side frameworks and modules for a web‑based Learning Management System (LMS), including Java Servlets, JSPs, Tomcat integration, data parsing, and backend workflow logic.
• Manipulate XML and JSON structures to support LMS configuration, data exchange, and system automation.
• Use ANT and Gradle in build and deployment pipelines supporting LMS environments.
• Work across both Linux (RHEL/Bash) and Windows (shell scripting) operational environments.
• Learn and apply new programming languages and technologies, with mentorship and support from experienced teammates.
• Occasionally support hardware system configuration and build‑out, gaining exposure to full system integration.

This opportunity is ideal for developers who thrive on solving complex problems, want to expand their technical expertise, and are motivated by work that directly supports the U.S. Navy’s operational readiness.

Primary Responsibilities

• Work collaboratively in an agile team environment supporting a large‑scale program.
• Own and deliver backend software solutions in Java SE, Servlets, JSP, and related LMS technologies.
• Maintain and extend server‑side LMS modules running in servlet containers such as Apache Tomcat.
• Implement parser logic using JavaScript and apply HTML5 concepts where needed in LMS workflows.
• Manipulate XML and JSON files in support of LMS configuration and data integration.
• Utilize ANT and Gradle build tools for compiling, packaging, and deploying workflows.
• Work in both RHEL Linux and Windows environments, including Bash and Windows shell scripting.

Basic Qualifications

• Education: Bachelor’s degree in Computer Science, Computer Engineering, or a related field that provides strong software development skills.
• Experience: Around 5 years of hands‑on experience in one or more of the following:
  • Designing and developing real‑time acoustic signal processing algorithms
  • Building parallel processing solutions
  • Working with microservices
  • Developing software for signal processing, real‑time data analysis, or visualization/simulation systems
  • Developing Java‑based server frameworks or web application backends using Java SE, Java Servlets, JSP, XML/JSON manipulation, and related technologies
• Clearance: Must be able to obtain a U.S. security clearance.
• Certification: Must be willing to earn an IAT Level I (or higher) certification after hire (company‑supported).

Preferred Qualifications

• Familiarity with parser development or extending JSP libraries for dynamic content.
• Experience in integrating Java backend services with web front‑end frameworks.
