Your greatest work is ahead!

Leidos’ Defense Systems is seeking a Senior Systems Engineer to join a team of systems engineers developing hypersonic missile systems. In this role, the Senior Systems Engineer will help support early lifecycle reviews and design development by interfacing with the Software Development Team, Hardware Development Team, Analysis Team, Logistics Team, and Test & Integration Team. This Senior Systems Engineer will help develop systems engineering artifacts, including Requirements Specifications, Interface Control Documents, verification planning and reports, and Model-Based Systems Engineering (MBSE) content. It is an expectation for this role that the Senior Systems Engineer will start the effort with direct tasking but move into a more autonomous role as the program goes on.

The Senior 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 current program ends, the Senior Systems Engineer will have the opportunity to support a different program in the portfolio. A candidate with experience in other engineering areas such as Test, Model-Based Systems Engineering, 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.
