Senior Mechanical Engineer

BAE Systems is seeking an experienced Senior Mechanical Engineer to support our work as a prime contractor on high-profile U.S. Navy facility development, recapitalization, and construction projects. Accuracy, integrity, subject matter expertise, and the ability to work well independently and with others are important traits we expect the successful candidate to possess and demonstrate. This position is responsible for conceptual development, code compliance reviews, and ensuring SSP specific requirements are incorporated into the mechanical design portion of conceptual, preliminary and final design documentation.

This includes both BAE conceptual designs and designs created by other architectural engineering firm hired as the responsible engineer for the project. As a decades long sole source partner on multiple contracts on behalf of our customer, our program has remarkable stability and is concurrently experiencing significant growth. Combined, these factors provide ample opportunity for professional growth and development for capable and talented individuals on our team.

About the Program

Our organization has supported the U.S. Navy's Strategic Systems Program (SSP) continually since the program's inception in the 1950s. SSP developed the first sea-based, underwater-launched Strategic Weapon System (SWS), a defense system that is truly critical to our national security. For more than six decades, SSP has maintained and upgraded this weapon system and BAE has been there every step of the way.

The sea-based SWS is the ultimate stealthy weapon system and as the first leg of the U.S. nuclear triad. With over 70% of our nation's nuclear arsenal its importance to maintaining world peace cannot be overstated. The development of Columbia, the most advanced nuclear-powered, nuclear-armed submarine ever designed, as well the next D5LE2 weapon system is under way and will begin to be rolled out over the next decade.

The Navy expects this system to be operational through 2084, meaning the program will have a total life span of more than 120 years. This is a truly unique program and BAE Systems employees on this program understand they are part of an important legacy.
