About The Position

Leidos is seeking a senior Test Engineer (Level 4) to serve as a lead member of a team supporting the SkyLine-X KN-2 program. The role leads verification, validation, and qualification of advanced systems, with a focus on testing methodologies and systems integration for Air Traffic Control modernization initiatives. The engineer designs, implements, and maintains test frameworks and procedures aligned with systems assurance, safety, and performance standards. The team uses Artificial Intelligence (AI) and Machine Learning (ML) techniques to enhance testing; experience with these approaches is valued. The position provides technical leadership for systems and software integration, development test, and formal test execution. It involves integrating and validating capabilities in physical and virtual labs, supporting customer demonstrations and acceptance testing, performing deployment activities at operational facilities, and collaborating across software, systems engineering, networking, infrastructure, and customer teams. The engineer develops test strategies, procedures, automation, and documentation; troubleshoots complex system-level issues; and communicates status to stakeholders. The role may require overtime, off-hours, or weekend work to meet deadlines, and travel must be supported.
