Responsibilities

Build and operate the modeling backbone of a Digital Engineering Ecosystem supporting the customer.
Conduct day-to-day MBSE modeling activities, provide mission engineering support, and implement Digital Threads in collaboration with the platform engineering team.
Build, maintain, and evolve UAF and SysML (v1 and emerging v2) models supporting Digital Twins and the enterprise engineering baseline.
Configure and operate the Digital Engineering tool chain, including Cameo Enterprise Architect and its Simulation Toolkit, UAF, SysML, and DataHub plugins; Teamwork Cloud; and VS Code/SysIDE for SysMLv2 textual model validation.
Establish and maintain interoperability between MBSE and MS&A tools 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 Digital Engineering/MBSE and data-layer tool evaluations.
Support delivery of the repository of MBSE SysML models, the Digital Engineering data repository, tool deployments and integrations, and the Digital Engineering Management Plan (DEMP).
Collaborate with mission engineering and domain subject-matter experts to translate mission threads and measures of performance/effectiveness (MoPs/MoEs) into model-based artifacts.
Support engineering research, design development, and technical assignments in accordance with program specifications and within estimated time frames, budget constraints, and established quality standards.
