What You'll Do:
The Systems Engineer – Requirements & Interfaces provides systems engineering support to a large Government space and satellite communications program, with primary responsibilities in requirements development and management, interface definition and control, verification planning, and maintenance of the program technical baseline. The position works across multidisciplinary engineering teams to ensure system and subsystem requirements are well-defined, properly allocated, traceable, and verifiable throughout the system lifecycle. The Systems Engineer will develop and maintain Interface Control Documents (ICDs), requirements and verification artifacts, test documentation, and other systems engineering products necessary to support system integration and demonstrate compliance with program and customer requirements. You will work closely with space, ground, software, network, cybersecurity, integration and test, and other engineering disciplines to maintain alignment between requirements, interfaces, system architecture, design implementation, and verification activities.
Key Responsibilities:
- Support the development, decomposition, allocation, and management of system, subsystem, interface, and verification requirements
- Maintain end-to-end requirements traceability using the program requirements management environment
- Support Verification Cross-Reference Matrix (VCRM) development and maintenance, including verification methods, approaches, success criteria, and associated verification artifacts
- Develop, coordinate, and maintain Interface Control Documents (ICDs), Interface Requirements Documents (IRDs), and associated interface requirements between systems, segments, subsystems, external systems, and suppliers
