Experience configuring and supporting enterprise network devices, including routers and switches, with the ability to troubleshoot connectivity and network performance issues in operational environments. Proven ability to troubleshoot distributed systems across compute, network, and storage layers. Experience with security focused tasks: system hardening, compliance checks, audit readiness, and maintaining security controls. Effective communication and stakeholder engagement abilities; comfortable working with operations, cybersecurity, networking, and program teams. Ability to travel on short notice, up to approximately 25%, in support of deployment and operational activities. Desired Skills Knowledge of enterprise networking (routing, switching, DNS, load balancing) and storage technologies (SAN/NAS, replication, backup/recovery). Hands-on experience deploying and operating OpenShift clusters; familiarity with automation tools such as Ansible or Puppet. Experience serving as a technical anchor during large-scale deployment events or major operational incidents, providing informal mentorship to engineers.
