  • Contribute to software documentation, testing standards, and engineering best practices
  • Support continuous improvement initiatives focused on software reliability, automation, and long-term sustainment
Required Qualifications:
  • Bachelor's degree in Computer Science, Computer Engineering, Software Engineering, Electrical Engineering, or a related technical discipline
  • Strong experience developing software in C++
  • Experience troubleshooting software defects and supporting software integration activities
  • Understanding of software development lifecycle processes, software quality practices, and configuration management
  • Experience working within collaborative software development teams using peer reviews and version control
  • Ability to work independently while supporting a customer-facing engineering environment
  • Active Secret security clearance or the ability to obtain and maintain one
Preferred Qualifications:
  • Experience developing software in Ada
  • Experience supporting legacy software modernization efforts
  • Experience with automated testing frameworks and regression testing
  • Experience integrating automated testing into CI/CD or daily build environments
  • Experience supporting complex real-time, embedded, or defense software systems
  • Familiarity with Agile software development methodologies
  • Experience with static code analysis, code coverage tools, or software quality metrics
  • Experience developing unit tests for complex software systems
  • Familiarity with automated testing, regression testing, and build/test workflows
