Mission Systems Engineer - MBSE

SAIC is seeking a talented and motivated Model-Based Systems Engineer (MBSE) to support cutting-edge hypersonic programs at Naval Surface Warfare Center (NSWC) Crane . This is a high-impact role embedded at the customer site, working directly with government engineers and program teams on some of the Department of Defense's most technically challenging and strategically important hypersonic development efforts.

The ideal candidate brings a strong systems engineering foundation, hands-on experience with MBSE tools and methodologies, and the ability to engage across the full system lifecycle — from concept development through validation and verification.

What You'll Do

Core Systems Engineering Responsibilities

- Review and evaluate Technical Data Packages (TDPs) for completeness, accuracy, and compliance with program requirements
- Participate in and support Systems Engineering Technical Reviews (SETRs) , including:
- System Requirements Reviews (SRR)
- Preliminary Design Reviews (PDR)
- Critical Design Reviews (CDR)
- Test Readiness Reviews (TRR)
- Support Drawing Reviews and Model Reviews to ensure design integrity and traceability

MBSE & Architecture

- Develop, maintain, and update system architecture models using MBSE tools, with Cameo Systems Modeler as the primary platform
- Apply SysML or equivalent modeling languages to capture system structure, behavior, requirements, and interfaces
- Ensure model fidelity and consistency across program phases and stakeholder views
- Support transition from document-based to model-based engineering practices within the program

Systems Engineering Activities

Assist with and lead a broad range of systems engineering functions, including:

- Concept of Operations (CONOPS) formulation and documentation
- Requirements definition , decomposition, and management
- Technical analyses and trade studies to inform design decisions
- System architecting, analysis, and design activities
- System performance analysis and margin assessments
- Interface management including development and maintenance of Interface Control Documents (ICDs)
- Systems integration planning and coordination
- Validation and Verification (V&V) planning and execution support
- Preparation of engineering plans, process instructions , and technical documentation

Stakeholder Engagement

- Collaborate directly with government engineers, program managers, and technical leads at NSWC Crane
- Coordinate with contractors, subcontractors, and suppliers to resolve technical issues
- Communicate technical status, risks, and recommendations clearly in both written and verbal formats
