The Spacecraft Systems Engineer leads the technical execution and systems engineering lifecycle for spacecraft programs, guiding multidisciplinary teams through concept development, design, integration, testing, and in-orbit operations. This role ensures the spacecraft system architecture, requirements, and subsystem interfaces deliver a mission-ready vehicle — focusing on building and operating spacecraft, not just documentation.

Responsibilities:

• Lead spacecraft systems engineering activities including concept development, trade studies, CONOPS, requirements decomposition and allocation, interface definition, and system verification/validation.
• Develop and manage spacecraft system architectures, requirements, and subsystem interfaces across the vehicle lifecycle.
• Coordinate with subsystem engineers, manufacturing, integration & test teams, and program leadership to execute spacecraft development.
• Perform system-level analyses including power, mass, and performance budgets to optimize spacecraft design and architecture.
• Support satellite integration and test (I&T) activities and ensure mission functionality prior to operational deployment.
• Participate in software integration and verification testing for mission readiness.
• Investigate and resolve cross-functional technical issues and anomalies affecting spacecraft performance.
• Apply Model-Based Systems Engineering (MBSE) methods to define and manage spacecraft system architecture.
• Analyze technical data to validate system configurations against mission constraints and operational requirements.
• Contribute to systems engineering process improvement and risk management activities.
• Provide technical guidance and mentorship to junior systems and subsystem engineers.
• Collaborate with program management and financial leadership to ensure program execution aligns with schedule and mission objectives.

Qualifications:

• U.S. Citizenship is required by Federal Law
• Bachelor’s degree in Engineering or Science with 5+ years of spacecraft systems engineering experience
• Active Secret Clearance Required with ability to obtain a U.S. Top Secret Security Clearance
• 5+ years aerospace industry experience, preferably in spacecraft or satellite systems.
• Experience applying space systems engineering principles and lifecycle processes.
• Experience managing power, mass, and system budgets.
• Experience performing requirements analysis, decomposition, and flow-down.
• Experience with design verification and validation (V&V).
• Experience with configuration management practices.
• Experience supporting satellite-level integration and test (I&T).
• Experience with satellite in-orbit operations.
• Familiarity with program management tools and processes.
