## Description

SAIC is seeking a Senior Digital Engineer with experience in applying Digital Engineering or Model-Based Systems Engineering tools and techniques for Department of Defense (DoD) space-based systems. This role provides systems engineering and integration expertise in support of the Positioning, Navigation, and Timing (PNT) Systems Engineering & Integration (SE&I) Team.

PNT SE&I provides engineering, integration, technical analysis, and subject matter expertise (SME) support to the US Space Force. As a member of our PNT SE&I Team, you'll work in a high-paced environment with Government personnel and systems engineers to develop the PNT System Architecture using a dynamic MBSE methodology.

Major duties of this position include:

 * Apply MBSE tools and techniques to capture system architecture using the 9 standard SysML diagrams; building the structural/behavioral system perspectives; and defining operations, services, interfaces, and the concept of operations to establish a model-based system technical baseline.
 * Support requirements allocations and functional decomposition to hardware, software, and lower-level components of the system(s) within the models.
 * Integrate models from disparate stakeholders into a cohesive end-to-end environment to enable an end-to-end architectural definition.
 * Produce model-based products using scripts, including DoDAF products, to support program milestones and CDRL items.
 * Apply Simulation/Analysis to the Mission Architecture via Cameo's Simulation Toolkit, Matlab, and STK.
 * Help to establish best modeling practices with the Government to better enforce contractor SysML modeling standards.
 * Enable the generation of systems engineering documentation for requirements, ICDs, systems design, CONOPS, verification, and testing.
 * Collaborate with prime contractors, other team contractors, government stakeholders, and members of the U.S. Space Force.
