Qualified candidates must be U.S. citizens with an active TS/SCI clearance and be eligible to obtain a CI Poly. Responsibilities: Build and operate the modeling backbone of a Digital Engineering Ecosystem supporting NGA. This hands-on role drives day-to-day MBSE modeling activities, mission engineering support, and Digital Thread implementation in close collaboration with the platform engineering team. Stand up UAF/SysML models, integrating MBSE with Modeling, Simulation & Analysis (MS&A) tools, and delivering a modular, open, standards-based ecosystem of tools and pipelines supporting the program's Digital Engineering layer. The role supports engineering research, design development, and technical assignments in conformance with program specifications, ensuring deliverables are completed within estimated time frames, budget constraints, and established quality standards. Build, maintain, and evolve UAF and SysML (v1 and emerging v2) models supporting Digital Twins and the enterprise engineering baseline. Configure and operate the DE tool chain, including Cameo Enterprise Architect (with Simulation Toolkit, UAF, SysML, and DataHub plugins), Teamwork Cloud for model configuration management, and VS Code/SysIDE for SysMLv2 textual model validation. Establish and maintain interoperability between MBSE and Modeling, Simulation & Analysis (MS&A) tools (e.g., AFSIM, STK, Unreal Engine) to create Digital Threads linking engineering capabilities. Support requirements management integration with IBM DOORS Next and traceability tooling such as Syndeia. Participate in current-state capture, tool trade studies, and gap analysis for DE/MBSE and data-layer tool evaluations. Support delivery of the repository of MBSE SysML models, DE data repository, tool deployments and integrations, and the Digital Engineering Management Plan (DEMP). Collaborate with mission engineering/domain SMEs to translate mission threads and measures of performance/effectiveness (MoPs/MoEs) into model-based artifacts. Required Qualifications:* Bachelor's degree in Systems Engineering, Aerospace/Mechanical/Electrical Engineering, Computer Science, or a related field, or additional relevant experience in lieu of a degree. 10+ years of relevant MBSE/digital engineering experience. Hands-on experience building and maintaining SysML and/or UAF models using Cameo Enterprise Architect or comparable MBSE tooling. Experience with model configuration management (e.g., Teamwork Cloud) and requirements management tools (e.g., IBM DOORS/DOORS Next). Familiarity with digital thread concepts linking requirements, design, test, and operational data across the engineering lifecycle. Desired Qualifications:* Experience supporting NGA, DoD, or Intelligence Community digital engineering or modeling & simulation programs. Working knowledge of SysMLv2 and textual modeling tools such as SysIDE. Experience with Modeling, Simulation & Analysis (MS&A) tools such as AFSIM, STK, or Unreal Engine, or geospatial platforms such as ArcGIS. Experience integrating AI/ML-enabled workflows into modeling or requirements decomposition processes. INCOSE CSEP or equivalent certification.
