  • Manage configuration, maintenance, lifecycle administration, and hardware operations for bare-metal RHEL servers.
  • Diagnose network interface bonding, link aggregation, VLAN tagging, and connectivity problems.
  • Coordinate vendor hardware dispatches and replacement of physical components.
  • Carry out FedRAMP security operations, including vulnerability patching, system hardening, FIPS configuration, RBAC, SSH key management, and security-boundary enforcement.

  • Verify build compliance, container security scans, and image signatures before deployment.
  • Keep operational runbooks, standard operating procedures, and triage workflows up to date.
  • Reduce operational toil by developing Bash and Python scripts for monitoring, hardware checks, and maintenance.

  • Availability and ability to work a rotating 24/7 schedule, including nights, weekends, and holidays.
  • Strong hands-on administration experience with bare-metal RHEL servers, including hardware diagnostics, out-of-band management through IPMI, iDRAC, or iLO, RAID, LVM, and physical NIC bonding.
  • Direct experience querying and analyzing Kibana and Elasticsearch log streams using KQL or Lucene, index management, and log-pattern matching.
  • Practical experience troubleshooting Layer 4 and Layer 7 secure load balancing, mTLS, TLS termination, health checks, and secure traffic routing.
  • Solid operational experience with AWS core services, including EC2, VPC, IAM, S3, and KMS, plus familiarity with AWS GovCloud operating models.
  • Hands-on experience operating Amazon EKS and Kubernetes, including kubectl, Helm, pod lifecycle management, and node-pool maintenance.
  • Experience with Prometheus, PromQL, Alertmanager, and Grafana.
