Standard 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. Join us in shaping a new era in space and find a career that's built for you. Lockheed Martin is designing, developing, and delivering a next-gen wideband MILSATCOM system comprised of integrated space and ground segments that will provide enhanced communications capacity, flexibility and resiliency. This position will be a key member of the Systems Engineering, Integration and Test (SEIT) team in support of the final design, development, production, integration, test and delivery of this critical capability focused on Mechanical Systems Integration.

In This Role You Will

• Serve as an integration lead for different Mechanical subsystems
• Lead the definition of mechanical system interfaces
• Support the requirement decomposition and allocation process with the Requirements team
• Drive anomaly investigations to closure
• Lead the definition, analysis, and recommendation of Trade Study options related to the mechanical systems
• Perform data and document reviews and provide feedback for technical and program documentation
• Support systems/hardware integration, test planning and execution and find opportunities for build flow and test efficiencies

This position is contingent on program award, expected in 3Q 2026.

Applicant selected will be subject to a government security investigation and must meet eligibility requirements for access to classified information.
