The System Integration/Test Engineer will plan, implement, test, document, and maintain solutions for the integration and testing of in-house developed and COTS/GOTS components, elements, subsystems, and/or systems. The role involves synthesizing customer contractual needs and requirements into system test solutions that acknowledge technical, schedule, and cost constraints. The engineer will establish functional and technical specifications and standards, solve hardware/software interface problems, define input/output parameters, and ensure integration of the entire system or subsystem. Responsibilities include reviewing, evaluating, and deriving requirements for testability, developing and directing preparation and execution of comprehensive test plans, procedures, and schedules for complete systems and/or subsystems. The engineer will coordinate subsystem and/or system testing activities with programs and other organizations, perform analysis of test results, and prepare comprehensive subsystem and/or system level evaluation reports which verify and validate system performance. Additionally, the engineer will write discrepancy reports and perform integration regression testing to verify/validate incorporated fixes to software, components, subsystems, and systems.
