• Participate in and support formal software reviews, including software requirements reviews, preliminary design reviews, critical design reviews, integration readiness reviews, and software acceptance reviews.
• Apply object-oriented design and development techniques, including the use of design patterns and software insulation techniques to enable modularity and plugins.
• Develop and maintain software in C++ or Java within Linux and other UNIX variants, following established life cycle processes and procedures.
• Create and maintain scripts for Solaris and other UNIX variants to support development, integration, and test activities.
• Use Integrated Development Environments (IDEs) such as Eclipse to develop, debug, and maintain software solutions.
• Apply UML syntax to document and communicate software architecture and design.
• Write and execute unit tests using xUnit frameworks such as JUnit and CppUnitLite to ensure software quality.
• Contribute to the documentation of new and existing software, including design descriptions, test procedures, and user documentation.
• Collaborate with cross-functional engineering teams to integrate software components into larger systems and resolve integration issues.
• Follow CMMI Level 5 life cycle processes and procedures to ensure high-quality, repeatable engineering practices.
