Automate infrastructure using scripting and Infrastructure-as-Code
Patch, harden, and secure systems in compliance with security standards
Manage LDAP-based user accounts and core Linux services (DHCP, DNS)
Support Kubernetes-based containerized workloads
Participate in architecture discussions and cross-team engineering efforts
Contribute to incident response and root cause analysis
#MDFSP
7+ years of Linux systems administration experience
5+ years scripting (Bash, Python, or Perl)
Experience supporting large-scale distributed systems across multiple clusters
Hands-on experience with Hadoop, Accumulo, and distributed storage technologies
Experience with Kubernetes and Docker
Familiarity with automation tools (Puppet, Ansible, Salt) and IaC (Terraform or CloudFormation)
Knowledge of monitoring platforms (Prometheus, Grafana, ELK, Splunk)
Understanding of networking fundamentals (VLANs, TCP/IP, load balancing)
Experience with high-availability design, storage architecture, and disaster recovery
System hardening and security compliance experience
Active TS/SCI clearance with current polygraph
