Job Description:

Job Description Space is a critical domain, connecting our technologies, our security and our humanity. While others view space as a destination, we see it as a realm of possibilities, where we can do more — we can innovate, invest, inspire and integrate our capabilities to transform the future. At Lockheed Martin Space, we aim to harness the full potential of space to cultivate innovation, reduce costs, and push the boundaries of what technology can achieve. We’re creating future-ready solutions, focusing on resiliency and urgency through our 21st Century Security® vision. We’re erasing boundaries and forming partnerships across industries and around the world. We’re advancing spacecraft and the workforce to fuel the next generation. And we’re reimagining how space can connect us, ensuring security and prosperity. For over 60 years, the Fleet Ballistic Missile (FBM) team has supported the Navy’s mission to provide affordable and credible strategic defense. We offer unique career opportunities and challenges on a program with a rich history and exciting future. We help keep this nation and our allies secure. The FBM Program is experiencing significant growth, and we need your expertise to deliver amazing new technologies to our customers while maintaining the technical requirements of the strategic deterrence. Join us in shaping a new era in space and find a career that's built for you. Mass Properties Engineering is the art and science of predicting the Mass Properties of a satellite, missile, aircraft, land vehicle or marine system before it is built, assessing and supervising the Mass Properties all through development, and finally performing highly accurate measurements to prove to our customers it will perform as proposed. Our Mass Properties Engineers help ensure our spacecraft get payloads to the right orbit around our planet or around other objects in our solar system, help our missile systems intercept a threat and protect our troops, help deliver a payload with pinpoint accuracy, or help us develop smaller, lightweight directed energy weapons, so they can be deployed on a variety of platforms.
