A day in the life
One morning you might be reviewing a network architecture proposal for a new ground station deployment defining the segmentation and monitoring requirements before the first switch is racked. That afternoon a detection fires on anomalous lateral movement in a manufacturing network you triage it determine whether its a misconfigured industrial controller or something worse and drive the response. The next day you could be leading a threat model for a new OT protocol integration at a launch site. When youre not responding to active events you will be evaluating Leos network security posture end-to-end: identifying architectural weaknesses proposing new detection initiatives and driving cross-team programs that raise the bar across every site type.

You will have the freedom to prioritize as needed to balance your personal life professional growth and the delivery of your assigned projects.
