Develop, modify, and optimize Java-based software supporting Navy control systems.
Analyze existing software architecture and implement enhancements, bug fixes, and performance improvements.
Support integration and testing activities within hardware-in-the-loop laboratory environments.
Assist with troubleshooting software and system-level issues during laboratory testing and fleet support activities.
Participate in shipboard installation, testing, and commissioning efforts as required.
Support software validation, regression testing, and system verification activities.
Contribute to the development of internal test tools, automation utilities, and engineering support applications.
Collaborate closely with software developers, systems engineers, electrical engineers, and government stakeholders.
Investigate software defects, identify root causes, and implement effective corrective actions.
Participate in peer code reviews and maintain high standards for software quality and documentation.
Assist with technical documentation supporting software releases and testing activities.
