Responsibilities include but are not limited to:

• Designing, developing, and implementing complex, modular, and extensible representations of satellite communications (SATCOM) architectures using Cameo.
• Leading the derivation of intermediate logical layers using "middle-out" inference techniques to identify innovative solutions based on high-level technical data.
• Architecting multi-domain models capturing space, ground, and user segments while ensuring end-to-end API connectivity for the System’s Pathway Portal.
• Generating and maintaining systems software engineering policies and procedures for configuration control and version history using Teamwork Cloud (TWC).
• Ensuring system models are successfully implemented to guarantee compatibility with USSF workflows and DoW digital thread environments.
• Communicating complex concepts to stakeholders and influencing teams to adopt advanced MBSE methodologies.
• Working with all stakeholders to ensure complete and functioning systems that meet all requirements and technical standards.

Minimum Qualifications:

• Bachelor’s degree in Systems Engineering, Aerospace Engineering, Electrical Engineering, Computer Engineering, or a related technical field.
• 7+ years of relevant systems engineering experience in defense or aerospace environments.
• Advanced proficiency in Cameo Systems Modeler and SysML (1.6 or v2 equivalent).
• Demonstrated experience developing model-based architectures for SATCOM, space systems, or complex defense platforms.
• Hands-on experience modeling application programming interfaces (API) or system interfaces within digital workflows.
• Proven ability to work independently, solving complex problems with specialized depth and minimal guidance.

Preferred Qualifications:

• Active OCSMP (OMG-Certified Systems Modeling Professional) or similar MBSE credentials.
• Deep understanding of Multi-Orbit/Multi-Band (MOMB) mission planning or hybrid-space architectures.
• Familiarity with modeling complex telecommunications standards, such as Lifecycle Service Orchestration (LSO).
• Self-starter with excellent people skills who can drive change and technical excellence throughout an organization.

Clearance Requirements:

• Must be able to obtain and maintain a DoD TS/SCI clearance

Physical Requirements:

• Must be able to remain in a stationary position 50% of the time.
• Frequently communicates with co-workers, management, and customers, which may involve delivering high-level technical presentations to executive stakeholders. Frequently communicates with co-workers, management, and customers, which may involve delivering presentations.
• Must be able to exchange accurate information in these situations.
