## Description

NineFX is seeking a Systems Engineer Level 3 to support advanced systems engineering activities across Linux/Unix, Windows Server, VMware ESXi, Dell/HP server hardware, and NetApp storage environments in mission-critical government settings. The SE3 leads engineering design, integration, test planning, lifecycle management, and secure configuration across complex multi-platform infrastructures.
This role integrates hands-on system administration with formal DoD systems engineering-including requirements analysis, architecture development (DoDAF/SOA), interface definition, CCB support, risk assessments, and modeling/simulation.

What You'll Be Doing

Linux/Unix, Windows & Virtualization Engineering

 * Engineer, configure, secure, and maintain RHEL7+, Windows Server 2012+, and VMware ESXi environments
 * Manage kernels, OS installs, package configurations, system tuning, monitoring, and troubleshooting
 * Support Active Directory with Centrify integration; create/assign Linux identities and groups
 * Perform server hardware upgrades (Dell, HP, custom) including memory, disk, swap, and chassis maintenance
 * Execute NetApp storage migrations from legacy platforms to modern solutions

Security, Hardening & Vulnerability Management

 * Install and manage McAfee/Trellix and Nessus agents
 * Conduct vulnerability scanning and compliance activities (IAVA/CVE)
 * Patch and harden systems using Red Hat Satellite, WSUS, and approved STIG-aligned scripts

Systems Engineering & Architecture Development

 * Analyze system requirements, architectures, and CONOPS; refine functional and system specifications
 * Create system architectures using DoDAF and SOA approaches
 * Develop interface definitions, design solutions, and operational concepts
 * Coordinate CCB actions, technical reviews, and multi-discipline engineering issue resolution

Integration, Verification & Lifecycle Support

 * Support design, development, integration, verification planning, and engineering documentation
 * Define verification methods, evaluation criteria, and support certification/accreditation activities
 * Conduct trade studies, modeling/simulation, and system performance analysis
 * Maintain lifecycle technical baselines, configuration control, and compliance with national/agency standards

Technical Direction & Mission Engineering

 * Provide senior-level technical direction across hardware/software development, interface controls, and end-to-end flow analysis
 * Develop operational scenarios and design alternatives considering performance, resiliency, and cost
 * Participate in integration activities and ensure accurate interface control documentation
 * Support JCIDS documentation and all DoD-required systems engineering processes
