About The Position

As a System Specialist, you will play a critical role in serving as the primary diagnostic engine for our Network Operations Center (NOC), ensuring our infrastructure remains resilient and mission-ready. You will leverage your technical depth to independently navigate complex faults across interconnected network, OS, and identity layers, and partner closely with your Technical Support teammates to proactively identify cross-domain anomalies and implement scalable, documented solutions.

Requirements

5+ years of hands-on experience in a NOC, IT Operations, or hybrid Systems Support role, demonstrating a high degree of technical autonomy.
A "System of Systems" mindset with the ability to troubleshoot across multiple IT layers (Windows/Linux OS, Cisco routing/switching, and Identity/Access).
Proven experience viewing, querying, and extracting actionable data from enterprise monitoring stacks like Splunk and DataDog.
Strong practical experience navigating Cisco switch configurations via CLI, paired with comfort in a Linux command-line environment (e.g., SSH, grep, parsing daemons).
Demonstrated experience troubleshooting access and sync issues in Active Directory and Okta.
Must be a U.S. Citizen and able to obtain a DoD NIPR network account and Common Access Card (CAC)
Must have, or be able to obtain, a Secret Clearance.

Nice To Haves

CompTIA Security+, CCNA, or intermediate Linux certifications.
Experience supporting OT/ICS environments or working within DoD/Air Force spaces.
Basic scripting abilities (Bash, PowerShell, Python) used specifically for automating operational tasks.

Responsibilities

Serve as the independent, front-line diagnostic expert.
Diagnose and resolve complex network connectivity and identity access issues where the symptom may appear in one domain, but the root cause lives in another.
Act as the diagnostic shield for Engineering. When an issue exceeds the frontline scope, gather the exact telemetry, logs, and failure domain context required to execute a clean, actionable handoff to the capability teams.
Safely execute automated scripts and remediation playbooks to resolve known issues. If a runbook is outdated or missing a step, proactively update the documentation for the rest of the team.
Actively monitor network health using DataDog and Splunk. Go beyond the dashboards by writing custom queries and correlating raw logs to track down undocumented anomalies.
Use Linux command line and Windows PowerShell to verify system configurations, check local network states, restart stalled services, and safely execute pre-written remediation scripts without needing a full UI.
Provision, troubleshoot, and manage user access issues across Active Directory (AD) and Okta, verifying sync statuses and group policy enforcement.
Actively look for ways to eliminate manual work. When you solve a novel problem, immediately document the fix, write a basic script, or propose process improvements.
Maintain composure during mission-critical outages, providing clear, concise diagnostic updates to stakeholders while systematically working the problem.
