System Specialist

Simplesense•Denver, CO

4d•Hybrid

About The Position

As a System Specialist, you are the diagnostic engine of our Network Operations Center (NOC), playing a vital role in ensuring our infrastructure remains resilient and mission-ready. You will be responsible for keeping our hybrid infrastructure, spanning AWS GovCloud, on-prem Cisco edge networks, and complex identity systems resilient and mission-ready. You will dig into logs, trace cross-domain faults, and resolve OS, cloud, and network anomalies. You will partner closely with the broader User Success team to protect our production environments, eliminate alert noise, and deliver high-quality technical support to our critical end-users.

Requirements

5+ years of hands-on experience in a NOC, IT Operations, or hybrid Systems Support role, demonstrating a high degree of technical autonomy and operational discipline.
A habit of double-checking details (e.g., verifying identities and request specifics) before taking action. You take personal accountability for ticket resolution from intake to close—never shifting blame or leaving incomplete work for others.
A "System of Systems" mindset with the ability to troubleshoot across multiple IT layers (Windows/Linux OS, Cisco switching, and Identity/Access).
Proven experience viewing, querying, and extracting actionable data from enterprise monitoring stacks like Splunk and DataDog.
Practical experience navigating Cisco switch configurations via CLI, paired with comfort in a Linux command-line environment (SSH, grep, tailing logs, parsing daemons).
Proven ability to write clear, full-sentence updates for both internal engineering teams and external non-technical users.
Must be able to obtain DoD 8570/8140 IAT Level II certification (e.g., CompTIA Security+ CE) within 90 days of hire.
Must be a U.S. Citizen and capable of obtaining a DoD NIPR network account and Common Access Card (CAC).
Must have, or be able to obtain, a DoD Secret Clearance.

Nice To Haves

Prior experience working within DoD, Air Force, Space Force, or fast-paced Federal contractor/dual-use startup environments.
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, and familiarity with version control workflows (e.g., using GitHub for pull requests) or IaC principles.

Responsibilities

Troubleshoot and Resolve: Resolve network, OS, and cloud application access issues across hybrid environments.
Safely execute automated scripts and remediation playbooks to resolve known issues while demonstrating disciplined production execution with operational rigor in live production environments.
Support Ticket Triage & Escalation: Triage Support Tickets by directly resolving issues or gathering the telemetry, logs, and failure domain context required to execute a clean, actionable handoff to Engineering teams.
Collaborative Queue & Ticket Management: Actively manage ticket priorities alongside the team. Identify queue overflows early and share the load to resolve high-priority issues quickly. Maintain precise, real-time ticket logs to prevent duplicate work and ensure seamless handoffs.
Customer Communications: Translate technical findings into clear, complete, and empathetic updates for non-technical users.
Observability: Actively monitor network health using DataDog and Splunk.
CLI Operations: 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.
Identity Management: Provision, troubleshoot, and manage user access across Active Directory (AD) and Okta.
Toil Reduction: 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. Proactively update the documentation when a runbook is outdated or missing a step.
High-Stakes Execution: Maintain composure during mission-critical outages, providing clear, concise diagnostic updates to stakeholders while systematically working the problem.
