Your greatest work is ahead!
Leidos’ Defense Systems Land Systems is seeking a Systems Engineer to join a radar development team for a defense customer. Land Systems has a long history of radar development, including hardware design, algorithm development, and data analysis for a variety of customers.
This Model-Based Systems Engineer will join a team of seven other systems engineers, led by a senior systems engineer. In this role the Model-Based Systems Engineer will work with the broader engineering team to develop systems engineering artifacts in a Model-Based Systems Engineering environment using SysML and Cameo, including Requirements Specifications, Test Procedures, Test Reports, and CONOPS.
The selected candidate will interface with program management and design engineers to support a program’s systems engineering needs throughout its design life cycle, including modeling system behavior, defining the system architecture, dictating system interfaces, performing requirements verification, and helping develop test schemes. The selected candidate may present the systems engineering artifacts they have developed to the customer in formal design reviews and may serve as a customer liaison for MBSE content. 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).
