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.

The SDA's Tranche 2 and Tranche 3 Tracking Layers (T2TK/TRKT3) build upon the Transport Layer to transport high-fidelity mission payload data.

The successful candidate will have a commendable work ethic, good communication skills, a great attitude, be a results-oriented team player, creative thinker and problem-solver, and follow all ethical standards of the Lockheed Martin Corporation.
