Responsibilities

In this role, you will lead the creation of Model-Based Systems Engineering (MBSE) artifacts in SysML that translate conceptual architectures and analytical results into structured, interoperable system models. These models will support early-phase force design, architecture evaluation, and integration with external tools and analytical environments. This position is ideal for a systems engineer who can operate in ambiguous, concept-driven environments, and who excels at turning evolving ideas into coherent, defensible system models that inform decision-making.

Responsibilities

• Develop and maintain MBSE artifacts using SysML to represent candidate space architectures

• Translate conceptual system designs, trade study outputs, and mission scenarios into structured system models

• Create and manage core SysML artifacts, including:

• Block Definition Diagrams (BDDs)

• Internal Block Diagrams (IBDs)

• Activity and sequence diagrams

• Requirements diagrams with traceability

• Ensure models are structured to interface with external systems, analytical tools, and data environments, enabling integration across the broader analysis ecosystem

• Collaborate with trade space analysts, data scientists, and modeling & simulation teams to ensure alignment between analytical outputs and system representations

• Support development of system architectures, interfaces, and requirements for notional and emerging space capabilities

• Apply architecture frameworks (e.g., DoDAF, UAF) to ensure models are aligned with stakeholder expectations

• Maintain model integrity, consistency, and version control as architectures evolve

• Contribute to technical reports, briefings, and stakeholder engagements by translating model outputs into clear, decision-relevant insights

• Provide guidance on MBSE best practices and mentor team members on model-based approaches

Qualifications

Required

• Bachelor's degree in Systems Engineering, Aerospace Engineering, or a related technical field
• 5+ years of experience in Model-Based Systems Engineering (MBSE)
• Active TS/SCI or TS with SCI eligibility clearance and a willingness to obtain a CI Poly
• Demonstrated expertise in developing models using SysML
• Hands-on experience with MBSE tools such as:
• Cameo Systems Modeler
• Strong understanding of systems engineering principles, including:
• Requirements decomposition and traceability
• Functional and logical architecture development
• Interface definition and system integration
• Experience developing models that interface with external tools, data sources, or analytical environments
• Ability to translate ambiguous or evolving concepts into structured system models
• Strong communication skills and ability to collaborate across multidisciplinary teams

Preferred

• Experience supporting early-phase concept development, architecture definition, or pre-acquisition analysis
• Familiarity with architecture frameworks such as DoDAF or UAF
• Experience integrating MBSE models with:
• Modeling & simulation tools
• Data analytics pipelines
• External interfaces or APIs
• Background in space systems, including satellite architectures, ground systems, or mission analysis
• Experience with digital engineering environments or model integration across platforms
• Advanced degree in Systems Engineering or a related field
