Desired Skills * Active Top Secret clearance. * Experience supporting early program phases, driving testability assessments and requirements trade-offs between technical feasibility and program constraints. * Hands-on experience with test plan development, procedure authoring, and subsystem/system test execution. * Proficiency in test automation tools/languages (e.g., Python, LabVIEW, C++, MATLAB, or similar). * Experience with discrepancy reporting, integration regression testing, and root cause analysis of test failures. * Familiarity with MIL-STD or related test standards and protocols. * Demonstrated ability to balance testability, schedule, and cost objectives in a production environment. * Familiarity with subsystem verification/validation. * Additional familiarity with AS9100 audit processes or test environment certification processes is a plus. ## Description Plans, implements, tests, documents, and maintains solutions for the integration and testing of in-house developed and COTS/GOTS components, elements, subsystems and/or systems. Synthesizes customer contractual needs and requirements into system test solutions that acknowledge technical, schedule and cost constraints. Establishes functional and technical specifications and standards, solves hardware/software interface problems, defines input/output parameters, and ensures integration of the entire system or subsystem. Reviews, evaluates and derives requirements for testability, develops and directs preparation and execution of comprehensive test plans, procedures and schedules for complete systems and/or subsystems. Coordinates subsystem and/or system testing activities with programs and other organizations. Performs analysis of test results and prepares comprehensive subsystem and/or system level evaluation reports which verify and validate system performance. Writes discrepancy reports and performs integration regression testing to verify/validate incorporated fixes to software, components, subsystems and systems. Core Focus Areas for this Role * Interfacing with early stage/IRAD programs as an interface between program and production center to establish test planning activities and provide guidance on product testability to meet program requirements and schedule commitments. * Mentoring junior engineers on test processes, best-path-forward troubleshooting, test efficiencies, and technical writing. * Providing test expertise to the production center in automated processes and test efficiencies.
