• Plan, design, code, test, integrate, and deliver algorithms, models, software source code, executables, and computer programs in support of customer requirements.
• Analyze system-level requirements to ensure that test definitions, objectives, plans, and acceptance criteria are sufficient to validate system requirements and operational needs.
• Perform and support requirements development, validation, traceability analysis, risk assessment, and mitigation planning for software upgrades and development efforts.
• Support software testing activities including unit testing, software integration testing, system-level testing, regression analysis, and independent verification and validation (IV&V).
• Perform traceability analysis between requirements, test designs, cases, procedures, and execution results and document discrepancies in accordance with approved plans.
• Participate in code reviews, user acceptance testing, and development of automated software test results and documentation.
• Utilize Government-accessible source code repositories based on git and support disciplined software configuration management practices.
• Support software maintenance activities to correct faults, improve performance, address vulnerabilities, and adapt software to modified operating environments.
• Contribute to software architecture, quality assurance, requirement documentation, cloud-service support, and integration of software into larger mission systems and networks.
• Support work in both lab and field test environments, including Government-led testing and troubleshooting of integrated systems.
• Prepare technical reports, software documentation, and related engineering artifacts required to support development, testing, and sustainment. 

Education Level:

• Bachelor’s degree in Computer Science, Computer Engineering, Software Engineering, Electrical Engineering, or a related technical discipline.
