Job description

Description

SAIC is seeking MBSE SME supporting SAIC’s large SETA program, supporting the NRO’s Ground Enterprise Directorate (GED), Advanced Ground Office.

As an MBSE SME, you will shape how GED implements Digital Engineering, accelerates model‑centric acquisition, and evolves its engineering culture toward disciplined, repeatable, and data‑driven system development — a priority echoed across DoD and the Intelligence Community. You’ll guide enterprise modeling strategies, mentor engineering teams, and architect the digital threads that connect requirements, CONOPS, interfaces, and mission workflows across complex ground and space systems.
Key duties of this position include (but are not limited to):

• Lead enterprise MBSE strategy and execution. Apply systems engineering, systems modeling, product‑lifecycle management, and digital‑thread methodologies to construct, curate, and steward end‑to‑end digital content across GED programs.
• Capture and model customer needs, Translate mission needs into model‑based requirements, architectures, and CONOPS for future NRO ground and space systems.
• Develop authoritative system models. Build and maintain SysML/UAF models representing architecture, interfaces, operational workflows, and requirements traceability.
• Drive MBSE thought leadership. Evolve repeatable, disciplined systems‑engineering approaches grounded in MBSE principles, ensuring alignment with DoD digital‑engineering guidance.
• Support acquisition engineering. Develop model‑based requirements and artifacts for SOWs, RFPs, and technical evaluations; support proposal assessments using model‑centric criteria.
• Shape future space‑capability architectures. Work across multiple NRO and partner organizations to identify, define, and model future mission needs and enabling capabilities.
• Facilitate cross‑enterprise technical integration. Coordinate discussions with SMEs, government stakeholders, SETA teams, FFRDC partners, and development contractors to mature system concepts and resolve technical issues.
• Manage technical and acquisition dependencies. Identify, track, and communicate interdependencies across programs, architectures, and contractor deliverables.
• Champion digital‑engineering transformation. Mentor teams, guide tool adoption, and help GED accelerate its shift toward model‑driven engineering, automated workflows, and resilient ground‑system modernization.

Qualifications

Required Education and Experience:

• Bachelors and eighteen (18) years or more experience; Masters and sixteen (16) years or more experience; PhD or JD and fifteen years or more experience. Relevant experience to be substituted in lieu of degree.
• Active Top Secret Clearance with Polygraph.
• 10+ years of experience with system engineering processes and demonstrable expertise developing ground architectures for mission-critical systems.
• Background supporting or leveraging GEOINT or SIGINT intelligence discipline.
• In-depth experience with Digital Engineering principles, including model-based systems engineering (MBSE) approaches and tools.
• Practical understanding of Agile practices within system acquisition environments.
• Demonstrated expertise in government acquisition strategies, documentation development, and full lifecycle program management.
• Strong collaboration and communication skills, including the ability to brief government stakeholders at all levels.

Target salary range: $200,001 - $240,000. The estimate displayed represents the typical salary range for this position based on experience and other factors.
