Systems Administrator - Tier II

Yield Solutions Group

Englewood, CO 80112

$80,000-$100,000/yr

~ 21 min OnsiteHealth InsurancePaid Time OffRetirement Benefit

3+ years in a systems administration role, with clear Tier II or higher responsibilities (not just Tier I volume with a different title)
Active Directory administration: user and group management, group policy, troubleshooting authentication and access issues in Windows-based environments
Microsoft Intune: configuration policy management, compliance policy enforcement, device enrollment, and the compliance reporting that SOC 2 audits require
Microsoft Autopilot: deployment profile creation and assignment, enrollment troubleshooting, and hardware provisioning workflows for new and replacement devices
AWS IAM at an operational level: creating and managing roles, policies, and users; identifying and resolving access misconfigurations; understanding how IAM interacts with services running in the environment
Datadog or equivalent monitoring platform: alert acknowledgment, runbook execution, escalation workflows, and enough observability literacy to know when an alert is noise versus signal
Network fundamentals applied in practice: DNS and DHCP configuration management, VPN troubleshooting beyond the client layer, firewall ACL review, routing concepts sufficient to diagnose and describe connectivity issues accurately
Backup and recovery: hands-on experience verifying job completion, executing restore tests, and documenting results for production database environments
GitLab or equivalent DevOps platform administration at the admin level — not just as a user
SOC 2 operational familiarity: what documentation compliance looks like in practice, what an auditor expects, and how to build habits that hold up under review
Written communication that produces clear, self-contained runbooks and change logs — not notes that only make sense if you wrote them
