Leidos’ Defense Systems Land Systems is seeking a Junior Systems Engineer to join a team of systems engineers developing a radar system for the Air Force. The team consists of 2 other systems engineers, led by a senior systems engineer. This Systems Engineer will develop systems engineering artifacts, including Requirements Specifications, Test Procedures, Test Reports, and Model-Based Systems Engineering (MBSE) content. A strong background in requirements development is required for this position, not necessarily to be a subject matter expert in radar design or MBSE content development. This Systems Engineer may have the opportunity to present their work in formal settings to the customer and travel to customer sites / subcontractor sites (approximately 10% of the time).

The 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 radar program ends, the Systems Engineer will have the opportunity to support a different program in the matrixed engineering portfolio. A candidate with experience in other engineering areas such as Test, Model-Based Systems Engineering, Human Factors, Risk Management, and Reliability Analysis will be treated preferentially. However, a strong background in traditional systems engineering and technical leadership is what is required for this position.
