About the Job

Requirements

  • Five or more years of hands-on experience in a NOC, IT Operations, or hybrid Systems Support role, demonstrating technical autonomy and operational discipline.
  • Double-check details, including identities and request specifics, before taking action; own ticket resolution from intake through close.
  • Troubleshoot across Windows and Linux operating systems, Cisco switching, and identity and access systems.
  • Have experience viewing, querying, and extracting actionable data from enterprise monitoring tools such as Splunk and Datadog.
  • Have practical experience navigating Cisco switch configurations via command-line interface and comfort with a Linux command-line environment, including SSH, grep, log tailing, and parsing daemons.
  • Write clear, complete updates for internal engineering teams and external non-technical users.
  • Be able to obtain DoD 8570/8140 IAT Level II certification, such as CompTIA Security+ CE, within 90 days of hire.
  • Be a U.S. citizen and capable of obtaining a DoD NIPR network account and Common Access Card (CAC).
  • Have or be able to obtain a DoD Secret clearance.

Responsibilities

  • Resolve network, operating system, and cloud application access issues across hybrid environments; safely execute automated scripts and remediation playbooks to address known issues while following disciplined operational practices in live production environments.
  • Triage support tickets by resolving issues or gathering telemetry, logs, and failure-domain context for actionable handoffs to Engineering teams.
  • Manage ticket priorities with the team, identify queue overflows early, share workload to resolve high-priority issues, and maintain accurate, real-time ticket logs to prevent duplicate work and support seamless handoffs.
  • Translate technical findings into clear, complete, and empathetic updates for non-technical users.
  • Monitor network health using Datadog and Splunk.
  • Use Linux command line and Windows PowerShell to verify system configurations, check local network states, restart stalled services, and execute pre-written remediation scripts without a full user interface.
  • Provision, troubleshoot, and manage user access across Active Directory and Okta.
  • Identify and eliminate manual work; document novel fixes, write basic scripts or propose process improvements, and update outdated or incomplete runbooks.
  • Remain composed during mission-critical outages, provide concise diagnostic updates to stakeholders, and systematically troubleshoot the problem.
  • Ramp up on support workflows, observability tools, lab environments, and escalation protocols; build relationships across User Success and Engineering teams.
  • Independently triage support tickets and alerts in the daily rotation; identify opportunities to standardize diagnostic processes, runbook execution, and cross-team handoffs.
  • Deliver a toil-reduction improvement used by the User Success team, improve repeatability or reduce manual effort for a high-volume support issue, participate in Kanban ceremonies and root-cause troubleshooting, and begin refining diagnostic workflows for complex, multi-layered faults.

Desired Qualifications

  • Prior experience working within the Department of Defense, Air Force, Space Force, or a fast-paced federal contractor or dual-use startup environment.
  • CompTIA Security+, CCNA, or intermediate Linux certifications.
  • Experience supporting operational technology/industrial control systems environments or working within DoD/Air Force spaces.
  • Basic Bash, PowerShell, or Python scripting for operational task automation, familiarity with version-control workflows such as GitHub pull requests, or infrastructure-as-code principles.
