About The Position

At Lockheed Martin Space , we don’t just imagine the future—we build it. Our teams tackle some of the world’s most complex engineering challenges, delivering solutions that help protect lives and strengthen global security. Every day, our people bring passion, curiosity, and technical excellence to missions that truly matter. One of those missions is missile defense. Through constant innovation and deep collaboration, we design and integrate advanced systems that can detect, track, and intercept missile threats across all domains. What was once science fiction—intercepting a missile with a missile—is now a proven reality. The Next Generation Interceptor (NGI) program represents the next leap forward in missile defense capability. This program brings together cutting-edge technology, disciplined engineering, and mission-driven professionals to deliver solutions that could redefine how the world responds to emerging threats. Role Overview Lockheed Martin is seeking a Senior Systems Integration & Test Engineer to support the NGI program within an Assembly, Integration, and Test (AIT) environment. In this role, you will help ensure complex missile defense systems are correctly assembled, integrated, tested, and delivered—working hands-on with hardware, procedures, and multidisciplinary teams. This position is ideal for an engineer who thrives in high-impact environments, enjoys translating requirements into real-world execution, and is motivated by seeing advanced technology move from concept to operational reality.
