Northrop Grumman Space Systems in Chantilly, Virginia, is seeking an experienced Space Systems Engineer to join the rapidly growing Space Superiority Division.

You’ll join a cross-disciplinary team that develops, integrates, tests, and delivers advanced spacecraft and mission systems for space security missions. The ideal candidate will bring substantial experience or demonstrated technical depth in spacecraft engineering, space mission design, mission analysis, or mission operations and apply that expertise to complex, operationally focused space missions. This team’s work is backed by hands-on operational experience and a proven on-orbit track record. Northrop Grumman leads the industry in advanced space mission capabilities, and joining this team means working alongside the people who helped make that true.

As a Space Systems Engineer, you’ll help shape the spacecraft and mission across the full lifecycle-from mission architecture and concept development through detailed analysis, integration, test, launch, and on-orbit execution. You’ll solve challenging problems involving spacecraft performance, mission design, on-orbit operations, and system integration while helping deliver resilient capabilities for demanding and dynamic operational environments.

Primary responsibilities may include:

• Own the definition, control, and management of external system interfaces across complex, multi segment architectures.
• Develop, maintain, and baseline Interface Control Documents (ICDs), interface requirements, and associated models to ensure consistent, traceable implementation throughout the program lifecycle.
• Engage with stakeholders to provide recurring status (e.g., weekly metrics, execution health, schedule adherence).
• Produce high level and detailed technical artifacts such as interface diagrams, sequence/flow diagrams, data models, and API/interface contracts.
• Working with mission partners to model and mature mission elements, operational concepts, interfaces, and execution plans.
• Developing and managing mission, system, and subsystem requirements, including decomposition, allocation, traceability, verification, and validation.
• Defining and managing internal and external interfaces among spacecraft, payloads, host vehicles, sensor suites, ground systems, and mission partners.
• Supporting major program milestones, technical reviews, and mission-readiness reviews by developing technical content and translating complex engineering information into clear assessments and briefings for customers, program leadership, and other key stakeholders.
• Authoring and contributing to mission-engineering products, systems engineering artifacts, technical reports, and other critical program deliverables.

This position is contingent upon the candidate obtaining final clearances and program access(es) within a reasonable period of time determined by the company.

• Level 3: Bachelor’s degree with 5 years of professional experience or Master’s degree with 3 years of professional experience or PhD with 1 year of professional experience
• Level 4: Bachelor’s degree with 8 years of professional experience or Master’s degree with 6 years of professional experience or PhD with 4 years of professional experience
• Requires an active Top-Secret/Sensitive Compartmented Information (SCI) clearance at time of application

• Demonstrated experience supporting the development of a space or ground system

• Demonstrated Systems Engineering experience (e.g., requirements management, system architecture development, CONOPs development, mission engineering, modeling and simulation), * Experience developing and managing Interface Control Documents (ICDs), interface requirements, and associated models across the system lifecycle.
• Experience with external interface integration, API onboarding, or modernization efforts (e.g., migrating or integrating with new enterprise platforms or services).
• Experience with enterprise platforms/APIs for command and telemetry interfaces.
• Experience in modeling and documenting interfaces and software designs using tools such as SysML/UML, sequence diagrams, data models, and API specifications.
• Experience developing technical briefings and communicating complex engineering information to senior technical, program, customer, or executive stakeholders.
• Experience collaborating across multiple engineering disciplines to resolve technical issues and develop integrated spacecraft or mission solutions.
• Experience in Space Superiority mission design, satellite ground software, distributed modeling & simulation
• Mission system requirements, verification/validation planning, mission planning/execution, mission analysis, modeling/simulation, system trade studies
