The NASA IT portfolio within the Digital sector at Leidos currently has an opening for a Red Hat Enterprise Linux (RHEL) Endpoint Administrator. This is a telework position, but applicants must reside within reasonable commute distance from a NASA operating center and have flexibility to go on-site when needed for specific activities. This is an exciting opportunity to use your experience supporting the NASA End-user Services and Technologies (NEST) mission.
