We are seeking a Senior Enterprise Services Systems Engineer to support the Space Development Agency (SDA) Ground Management and Integration (GMI) program within the Proliferated Warfighter Space Architecture (PWSA). This role focuses on systems engineering documentation, requirements management, interface control, and architecture development for mission-critical satellite ground systems, cloud and hybrid infrastructure, and enterprise network services supporting national security operations.

This role supports PWSA Tranche 2 (T2) ground system development and integration, including SUPERNOVAs, NOVAs, Ground Entry Points (GEPs), Operations Centers, and associated ground networks. The GMI program continues Tranche 1 (T1) Operations and Integration (O&I) ground segment capabilities while supporting future tranche development. You will provide technical leadership across enterprise services engineering, system architecture, requirements traceability, and interface documentation for complex distributed defense systems.

Responsibilities:

• Develop, maintain, and sustain systems engineering documentation for enterprise network, cloud, demilitarized zone (DMZ), and hybrid infrastructure capabilities.
• Author and maintain system specifications, architecture descriptions, design documents, Interface Control Documents (ICDs), Architecture Description Documents (ADDs), network diagrams, and technical baselines.
• Translate stakeholder requirements, operational concepts, and technical specifications into complete, traceable systems engineering documentation.
• Develop and maintain ICDs for network, cloud, external mission partner, Operations Center, Ground Entry Point (GEP), SVV, and enterprise services interfaces.
• Collaborate with Network Engineering, Cloud Engineering, Cybersecurity, Operations, Integration and Test, Systems Engineering, and external stakeholders to validate technical requirements and resolve interface issues.
• Ensure engineering documentation reflects deployed configurations, approved architectures, planned capability increments, system interfaces, and technical decisions.
• Support requirements decomposition, allocation, traceability, verification planning, and requirements traceability matrix updates.
• Participate in technical interchange meetings, design reviews, architecture working groups, Documentation Readiness Reviews (DRRs), and configuration control activities.
• Coordinate technical document reviews, resolve stakeholder comments, maintain version control, and manage documentation approval and release processes.
• Document current-state, planned-state, and future-state system architectures supporting PWSA tranche-based development and integration.
• Identify documentation gaps, outdated technical artifacts, interface inconsistencies, and system dependencies; develop corrective action plans.
• Support technical estimates, engineering schedules, work plans, and backlog development for systems engineering and documentation activities.
• Provide systems engineering leadership by establishing documentation priorities, quality standards, completion criteria, and technical delivery commitments across the Enterprise Services team.

Qualifications:

• U.S. citizenship is required due to the nature of work performed within classified facilities.
• Active Department of Defense (DoD) Secret Security Clearance at time of hire, with the ability to maintain clearance throughout employment.
• Bachelor's degree in Systems Engineering or a related Science, Engineering, or Mathematics field with a minimum of 8 years of relevant experience; or a Master's degree with a minimum of 6 years of relevant experience.
• Minimum 15 years of recent experience designing, integrating, or sustaining complex distributed software systems.
• Minimum 10 years of recent experience supporting satellite ground systems or comparable national security mission programs.
• Minimum 5 years of recent experience working in cloud or hybrid-cloud environments.
• Demonstrated experience developing systems engineering documentation for complex network, cloud, or hybrid-cloud infrastructure.
• Experience developing and maintaining system specifications, architecture documentation, ICDs, ADDs, network diagrams, and engineering technical baselines.
• Experience with requirements decomposition, allocation, traceability, verification planning, and configuration management.
• Knowledge of enterprise network architectures, cloud infrastructure, system interfaces, and distributed software environments.
• Experience coordinating technical documentation, engineering reviews, and cross-functional systems integration activities.
• Ability to provide technical leadership, resolve engineering documentation issues, and support complex customer and mission requirements.

Preferred Qualifications:

• Experience supporting Space Development Agency (SDA), Proliferated Warfighter Space Architecture (PWSA), or Ground Management and Integration (GMI) programs.
• Familiarity with AWS GovCloud and/or AWS Secret Commercial Cloud Services (SC2S).
• Knowledge of cloud networking technologies, including Virtual Private Clouds (VPCs), Transit Gateways, AWS Direct Connect, load balancers, security groups, and Infrastructure as Code (IaC) concepts.
• Experience applying technical standards and systems engineering methodologies to complex defense and national security systems.
• Experience identifying opportunities to apply artificial intelligence (AI) to engineering process improvement, documentation efficiency, and innovation.
