Systems Administrator; IT & Network

Position: 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.

The ideal candidate is a broadly capable IT professional who can independently manage the full range of operational IT functions in a DoN environment - from NMCI/NGEN-Next account provisioning and trouble resolution to DISA STIG compliance and coordination with base ISSM/ISSO and Navy Network Operations Centers - while also administering F3EA's Microsoft 365 GCC-High environment, Intune-managed endpoints, Ninja One RMM platform, and CUI handling controls for the onsite team.

This is a hands-on, self-directed role with minimal local supervision in a fast-paced R&D environment.

• Track and manage IT service requests and trouble tickets through Navy and NMCI service portals (e.g., NMCI Homeport, myNMCI). Maintain current knowledge of DoN IT service request processes, approval chains, and lead times to proactively resolve access and connectivity requirements before they impact program milestones.
• Coordinate visitor IT access, temporary network accounts, and conference/event IT support for Government-directed meetings, technical reviews, and RDT&E events at PMSR.

• Manage Ninja One RMM agent deployment, monitoring, and patch management operations across the Point Mugu endpoint fleet. Document all support activities, resolutions, and escalations in the Ninja One FedRAMP ticketing system with sufficient detail for audit and compliance purposes.
