We have an exciting opportunity for a Model Based Systems Engineer to join the team with Barrios Technologies, a teammate company. We are seeking a highly experienced Senior Lead Systems Engineer with deep expertise in Model-Based Systems Engineering (MBSE) and human spaceflight programs and ground systems integration to lead the development and integration of complex aerospace systems. The ideal candidate will provide technical leadership across the full systems engineering lifecycle—from concept through verification and validation through Sustainment—using MBSE tools and methodologies to ensure mission success and safety compliance.

• Lead system architecture development and analysis using MBSE principles and tools (e.g., Cameo/Magic Draw, Rhapsody, Enterprise Architect).
• Define, manage, and validate system requirements, interfaces, and verification methods for crewed spaceflight systems.
• Develop and maintain SysML models to support system design, trade studies, and mission assurance.
• Collaborate with multidisciplinary teams (safety, reliability, human factors, propulsion, avionics, etc.) to ensure systems meet NASA and industry standards for human spaceflight.
• Participate in design reviews, technical interchange meetings, and customer presentations.
• Guide and mentor junior systems engineers in MBSE techniques and systems engineering best practices.
• Support risk management, configuration management, and requirements traceability throughout the project lifecycle.
• Interface with NASA, commercial partners, and subcontractors to coordinate system-level design integration.

• Typically requires a minimum of a bachelor’s degree in Engineering and a related master’s degree may be expected.
• Bachelor's degree in Systems Engineering, Aerospace Engineering, or a related discipline.
• Minimum 10 years of experience in systems engineering, including 5+ years applying MBSE methods in large, complex aerospace or spaceflight programs.
• Proven experience supporting ground systems, human spaceflight or crewed spacecraft programs (NASA, commercial, or equivalent).
• Expert-level proficiency with SysML and MBSE tools (Cameo/Magic Draw preferred).
• Strong understanding of systems engineering processes per NASA NPR 7123.1, MIL-STD-499C, or INCOSE SE Handbook.
• Demonstrated ability to lead cross-functional teams and deliver high-quality technical documentation.
• Excellent written and verbal communication skills.

• Master's degree in Systems Engineering, Aerospace Engineering, or a related field.
• INCOSE CSEP or ESEP certification.
• Experience with NASA human-rating standards and processes (e.g., NPR 8705.2, 8715.3).
• Familiarity with DOORS, JAMA, or other requirements management tools.
• Experience with digital engineering frameworks and integration with simulation or data management tools.

• Excellent personal and professional career growth.
