Systems Administrator-IT-IC3, Group 95 (Top Secret)
$95.7k - $126.7kLincoln Laboratory
The Space Systems Analysis and Test Group (95) identifies and evaluates threats to U.S. use of space for military, intelligence, civil and commercial purposes. This work involves understanding the attributes and vulnerabilities of U.S. space-related systems, including the sensors and networks used to detect, track, and characterize objects in space, the satellites that provide space-based services, and the infrastructure used to control and operate these satellites. A central component of this effort involves consideration of how adversaries might try to exploit U.S. vulnerabilities; assessing the risk of exploitation involves technically evaluating the knowledge and resources required to mount a credible threat against our systems. This work requires detailed modeling of optical, radar, and propulsion systems; novel ideas for new space systems and on-orbit operations; and understanding the timelines, architectures, and decision-making processes for maintaining awareness of the space environment. In addition, the group pursues potentially game-changing, innovative ideas for remote sensing of space and the Earth. This part of our work involves sensor design, signal and image processing as well as space object and environmental phenomenology. The group seeks researchers from the physical sciences, including physics, mathematics, and chemistry, as well as from a wide range of applied disciplines (including electrical engineering, mechanical engineering, chemical engineering, aeronautics, astronautics and computer science).Job DescriptionGroup 95 is seeking a Level 3 IT Systems Administrator to join a highly collaborative team supporting one of MIT Lincoln Laboratory's largest and fastest-growing classified computing environments.
