Your greatest work is ahead!

Leidos’ Defense Systems Land Systems is seeking a Model-Based Systems Engineer to join a matrixed organization of systems engineers, model-based systems engineers, and specialty systems engineers. This Model-Based Systems Engineer will support between 1 and 3 efforts simultaneously, which they will need to autonomously balance throughout their 40-hour workweek. These efforts will be for a variety of applications, from physics-based modeling & simulation to hardware development, and will involve both classified and unclassified work. The Model-Based Systems Engineer will need to work independently on these efforts, defining their own tasking derived from customer needs and contractual documents, but MBSE technical oversight will be provided when needed. Each effort will require different specific model artifacts, but broadly the Model-Based Systems Engineer will use Cameo Systems Modeler and SysML to develop requirements specifications, system architecture content (bdd / ibd), and system behavioral content (act / stm). This position does not necessarily require an MBSE Subject Matter Expert, but the role does minimally require experience working independently on MBSE models, some model customization, and the ability to communicate with non-Systems Engineering stakeholders who are less familiar with MBSE approaches.

The Model-Based Systems Engineer will work in a matrixed organization, which supports multiple programs at once in a variety of engineering fields with all different team environments. When the efforts end, the Model-Based Systems Engineer will have the opportunity to support a different program in the matrixed engineering portfolio. A candidate with experience in other systems engineering areas such as Lead Systems Engineering, Human Factors Engineering, Risk Management, and Reliability Analysis will be treated preferentially. Success in this organization often leads to leadership positions in Model-Based Systems Engineering, Systems Engineering, and Systems Engineering Integration and Test (SEIT).

At Leidos, we don’t want someone who "fits the mold"—we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, “what’s next?” before the dust settles on “what’s now.”

If you’re already scheming step 20 while everyone else is still debating step 2… good. You’ll fit right in.
