About The Position

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.

Requirements

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.

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.
