At SES Space & Defense, we deliver secure, resilient connectivity and integrated space solutions for customers operating in the world’s most demanding environments. As part of SES S.A., a global leader in satellite-enabled communications, we combine capabilities across all orbits with extensive global ground infrastructure, managed networks, hosted payload solutions, and mission integration services to support communications, sensing, data transport, and operational resilience worldwide.

Our vertically integrated space and ground capabilities bring together satellite capacity, terrestrial infrastructure, advanced network technologies, and deployed user terminals to support mission‑critical government operations around the world. We are a trusted partner to the U.S. Federal Government and national security community, allied governments, NATO, NASA, and other civilian agencies, delivering reliable, high-performance solutions when mission success is critical.

At SES Space & Defense, our people are our competitive advantage. You’ll work alongside a mission-driven team committed to integrity, innovation, accountability, and delivering real‑world impact for customers whose missions matter most.

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
• Support interface definition and resolution across engineering teams, suppliers, and program stakeholders to maintain consistency between requirements, architecture, design, and implementation
• Identify interface gaps, conflicts, and inconsistencies and coordinate with responsible engineering organizations to drive issues to resolution
• Support development and maintenance of test plans, test procedures, test reports, verification matrices, compliance documentation, and other verification and validation artifacts
• Assist engineering teams in defining objective evidence necessary to demonstrate requirement compliance and verification…
