Leidos is an American technology and engineering services company created in 2013 when Science Applications International Corporation split in two, with Leidos taking the technical services and solutions business. It is one of the largest suppliers to the United States government, working across defence programmes, intelligence systems, civil agencies including the Federal Aviation Administration, and healthcare services for the Department of Veterans Affairs. Headquartered in Reston, Virginia, the company also builds security detection products for airports and borders, and has concentrated recent investment on trusted artificial intelligence and autonomy for mission environments.

Looking for an opportunity to make an impact?

At Leidos, we deliver innovative solutions through the efforts of our diverse and talented people who are dedicated to our customers’ success. We empower our teams, contribute to our communities, and operate sustainably. Everything we do is built on a commitment to do the right thing for our customers, our people, and our community. Our Mission, Vision, and Values guide the way we do business.

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.
