We are seeking an experienced Senior Systems Engineer to support advanced SATCOM engineering efforts for mission-critical defense programs. The selected candidate will participate in Agile ceremonies and technical reviews with subsystem developers while facilitating technical discussions and ensuring software configuration management, software testing, timely root cause analysis, and engineering best practices are consistently executed throughout the software development lifecycle.

The successful candidate will employ engineering and scientific disciplines to perform technical analyses for hardware and computer software selection and recommend strategies for successful integration within complex SATCOM architectures. This role supports software development and maintenance through structured Agile processes including formal tasking, peer reviews, testing, configuration management, validation, documentation, delivery, and installation., The Senior Systems Engineer will analyze Engineering Change Proposals (ECPs), software specifications, software modules, computer software configuration items, system integration risks, and mitigation strategies while providing technical support for software testing and implementation. The position requires a strong understanding of the WSOMSNet system of systems and its operational environment., This is a remote position requiring approximately 30% travel to Colorado Springs, CO; Frederick, MD; Tobyhanna, PA; and government operational sites throughout CONUS and OCONUS.
