## Description

We are seeking an Staff Software Verification Engineer to join a Mission Systems team that develops software applications supporting critical business and mission objectives. The incumbent will execute all phases of the software development lifecycle-requirements analysis, design, implementation, testing, and documentation-under very general supervision. Success requires strong teamwork, clear communication, and the ability to coordinate with Systems Engineering, Hardware Engineering, Program Management, and the Software Architecture group. Familiarity with Agile development, DevSecOps, DO-178C, C/C++, Python, Linux, GitLab, and Atlassian tools is desired., * Design and implement C/C++ test procedures that verify SRS high-level and SDD low-level software requirements.

 * Conduct laboratory investigations, troubleshoot software issues, and perform regression analysis to ensure continued compliance.
 * Develop and maintain traceability matrices linking test results to original requirements, guaranteeing full coverage and auditability.
 * Create detailed test plans, test procedures, and test reports; execute integration, verification, and validation (IV&V) activities in a software-development lab environment.
 * Define external and internal hardware/software interfaces as needed for verification setups; update Interface Control Documents (ICDs).
 * Collaborate with cross-functional teams (Hardware, Software, Integration/Test) to resolve verification findings and drive corrective actions.
 * Support documentation of verification activities and contribute to certification evidence packages.
 * Operate within a DevSecOps framework, applying CI/CD best practices to automate test execution and reporting.
 * Participate in team planning, status updates, and risk mitigation to meet technical performance, schedule, and cost objectives.
 * Provide technical guidance to junior engineers as needed
