Procon has recently made the transition to Microsoft 365 GCC and is looking for an experienced System Administrator to join our growing team. This role reports to the Manager of Information Technology and works closely with the Helpdesk Analyst and a 3rd Party Managed Security Service Provider (MSSP).

This role is ideal for an experienced Microsoft 365 System Administrator to configure, secure, and operate a cloud-first productivity environment for a 200+ person company. Role requires broad-based knowledge and experience and involves hands-on technical work with tenant administration; developing documentation; and policy governance.

We are seeking someone with experience supporting Microsoft Government Cloud (GCC or GCC High) tenants and implementing rules to handle Controlled Unclassified Information (CUI) is preferred.

Qualifications and Skills:

• Minimum 5–7 years experience administering Microsoft 365 for mid-size organizations.
• Experience operating Microsoft Government Cloud tenants (GCC or GCC High) or implementing NIST SP 800-171 controls in Microsoft 365 tenants is highly desired.
• Hands-on experience with Microsoft Intune / Endpoint Manager, Windows Autopilot, Microsoft Defender, Entra ID / Azure AD, Exchange Online, Teams, and Microsoft Purview.
• Experience implementing Microsoft Purview (DLP, retention, labels) or equivalent information protection controls.
• Familiarity integrating SaaS apps (SSO/SAML/OAuth), managing app registrations, and configuring SSO.
• Proficiency with PowerShell, Microsoft Graph, and automation for evidence collection and control enforcement.
• Excellent documentation skills and experience creating runbooks and operational procedures.
• Active security mindset with experience responding to incidents and remediating threats.
• Background supporting remote/hybrid workforces and managing non-domain-joined devices.

Preferred Qualifications and Skills

• Microsoft certifications such as Microsoft 365 Certified: Endpoint Administrator Associate, Microsoft 365 Certified: Security Administrator, or Microsoft Certified: Identity and Access Administrator.
• Experience with Microsoft Sentinel, Intune Suite features, or Microsoft Copilot for Security.
• Familiarity with third-party MDM/MAM and backup solutions (e.g. Duo Federal).
• Experience in tenant-to-tenant migrations, domain changes, or hybrid identity projects.

Responsibilities and Duties:

Entra ID and Identity Security

• Harden identity configuration for CUI: implement strict Conditional Access policies, passwordless MFA, identity protection tuning, Privileged Identity Management (PIM), and emergency break-glass controls.
• Maintain identity logs and evidence retention to support audits and assessments against NIST SP 800-171 controls.

Intune and Device Management

• Enforce device posture for CUI access with Intune: strict enrollment gates, baseline configuration profiles, compliance policy strictness, controlled device enrollment (company-owned only where required), and device encryption enforcement.
• Manage Autopilot profiles and lifecycle to ensure new company devices meet CUI security baselines before granting access.

Defender and Threat Detection

• Deploy and operate Microsoft Defender for Endpoint and Defender for Office 365 with advanced telemetry, custom detection rules, automated containment playbooks, and integration into the tenant’s continuous monitoring and incident response processes.
• Ensure Defender signals feed into a centralized SIEM or Microsoft Sentinel for correlation, retention, and evidence for assessments.

Exchange Online, Teams, and Data Protection

• Configure Microsoft Purview for DLP, sensitivity labeling, encryption, retention, and eDiscovery tailored to CUI handling requirements.
• Implement strict guest access and external sharing controls for Teams, SharePoint, and OneDrive with exception workflows and approvals.

Tenant Governance and Configuration Management

• Maintain a formal tenant baseline configuration document, change control process, and Infrastructure-as-Code or scripted templates to reproduce hardened settings.
• Own periodic configuration drift checks, secure tenant setting reviews, and documented remediation actions for audit trails.

Logging, Monitoring, and Evidence Management

• Configure unified logging, retention, and automated evidence collection for controls mapped to NIST SP 800-171; ensure logs meet retention and integrity requirements for assessments.
• Produce and maintain artifacts required for audits: control evidence, configuration snapshots, access review records, and incident logs.

Third-Party and SaaS Integrations

• Vet and configure SSO and data flows for third-party SaaS (e.g. Adobe, Bluebeam, backups) to ensure minimal exposure of CUI and appropriate contractual, technical, and monitoring controls.
• Implement and enforce app consent and app registration governance in Entra ID.

Automation and Compliance Reporting

• Build PowerShell/Graph automation to produce recurring compliance reports, control evidence packages, license and entitlement reports, and remediation tickets for noncompliant items.

Other

• Address escalation requests from Helpdesk Analyst and MSSP as needed.

Salary commensurate with experience.
