  • Continuously tune alerting to reduce noise and improve signal quality.
Security Engineering & Compliance
  • Apply and maintain hardening baselines.
  • Support Risk Management Framework (RMF) artifacts, control documentation, and audit evidence collection.
  • Support vulnerability scanning, remediation tracking, and patch-compliance reporting.
  • Maintain system security documentation and configuration baselines.

  • Respond to technical issues after hours and participate in the on-call rotation.
Field & Deployed Support
  • Install and rack equipment and connect required cabling.
  • Perform physical setup and configuration of desktop hardware, software, and peripherals.
  • Build workstations in accordance with established procedures.
  • Deploy to geographically dispersed client facilities for hardware replacement, systems integration, and validation testing.
  • Provide technical direction and training to more junior engineers.
Required Qualifications
  • Degree in Computer Science, Computer Engineering, Systems Engineering, Information Technology, or a related field; candidates without a degree may qualify with 8-10 years of related experience on programs of similar size, scope, and complexity.
  • 8+ years of engineering experience supporting technical programs, with the majority in enterprise systems administration or infrastructure monitoring.

  • Strong TCP/IP troubleshooting: IPv4/IPv6, subnetting, VLAN/802.1Q, LACP, DNS, DHCP, NTP, routing/switching, ACL/firewall dependencies, and MTU.
  • Server, storage, network appliance, console, and workstation installation/troubleshooting, including out-of-band management such as iDRAC, iLO, XClarity, Redfish-based tools, or equivalent.
  • Working knowledge of CAT 5/CAT 6 cabling and connectors.
  • Experience with a ticketing platform, Visio, and Microsoft Office.
  • Physical capability to lift and mount equipment and work under raised floors.
Preferred Qualifications:
  • Microsoft certification at the MCSE or Azure Administrator level; RHCSA/RHCE; or VMware VCP.
