SAIC is seeking a Software Systems Engineer to support the Expeditionary Electronic Warfare Division at NSWC Crane. This position supports software development, design, and integration activities for Electronic Warfare (EW) systems, tactical information systems, and training environments under the JCREW program. The selected candidate will design, develop, modify, and maintain software and firmware throughout the system lifecycle. Additionally, this role involves testing software, performing requirements traceability, managing code repositories using git, and troubleshooting integrated systems in both lab and field environments.

Job Responsibilities:

• Design, develop, modify, integrate, test, and maintain computer software and firmware supporting Electronic Warfare systems, tactical information systems, test facilities, and training environments.
• Support software efforts across the lifecycle, including initial system design, new development, upgrades to fielded systems, and replacement of existing capabilities.
• 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.
