Systems Administrator (IT & Network Support)

Job Summary F3EA, Inc. is seeking an experienced Information Technology Specialist to provide onsite IT operations support at Naval Base Ventura County (Point Mugu Sea Range) for the Blue Water Instrumentation (BWI) RDT&E program. This position carries dual responsibilities: serving as the program's primary interface with Department of the Navy (DoN) IT infrastructure, networks, and administrative processes at NBVC, while simultaneously maintaining F3EA's internal IT operations, cybersecurity posture, and CMMC Level 2 compliance for all program personnel and equipment at the Point Mugu site. The IT Specialist operates alongside - but distinct from - the specialized R&D engineering team conducting prototype development. Where the engineering team manages developmental test environment cybersecurity under RMF, this position ensures that all operational IT infrastructure, user access, endpoint compliance, and corporate information systems are functioning, secured, and compliant at a Navy installation operating under both DoN policies and F3EA's own CMMC-governed security framework.
