Aprio is seeking a Senior Security Analyst to monitor, triage, and respond to threats across our managed security clients using the Microsoft security stack. You will serve as the first line of defense for dozens of client environments, working primarily in Microsoft Sentinel and Microsoft Defender XDR to detect, investigate, and contain threats before they cause harm. This role will carry a share of after-hours and on-call coverage to ensure clients are protected around the clock. Our Sentinel SOAR platform automates enrichment and first-response containment, allowing you to focus on investigation and judgment — not copy-paste triage.

You will deliver clear, client-ready incident communication and contribute to the continuous improvement of detection and automation capabilities across a growing managed security practice.

• Opportunity to protect dozens of client environments across a variety of industries using enterprise-grade Microsoft security tools.
• Hands-on experience with Microsoft Sentinel SOAR automation, including Logic Apps playbooks and multi-tenant management.
• Exposure to a structured, process-driven SOC with defined escalation paths, client runbooks, and direct client engagement.
• Ability to contribute directly to detection engineering, automation development, and continuous improvement of managed security services.
• Career growth within a high-performing managed security team at a nationally recognized professional services firm.

• 3–4 years of experience in a SOC, MSSP, MDR, or IT security operations role.
• Hands-on production experience with Microsoft Sentinel and Microsoft Defender XDR.
• Working knowledge of KQL.
• Solid understanding of Microsoft Entra ID, Microsoft 365, Windows endpoints, networking fundamentals, and common attack techniques (MITRE ATT&CK).
• Clear written and verbal communication skills, including composure and clarity during active client incidents.
• Availability and willingness to work evenings, weekends, holidays, and on-call rotations.
• Ability to work independently with minimal supervision.
• Working knowledge of Sentinel automation rules, incident tasks, and playbook triggers (incident, alert, and entity triggers).
• Sound judgment regarding when automation should be trusted and when it should be overridden.
• Microsoft SC-200 certification required, plus at least one of the following (or committed to earning within 90 days of hire): SC-300, AZ-500, AZ-104, or SC-401.

• Experience managing multiple tenants simultaneously through Azure Lighthouse or Defender XDR multi-tenant management.
• Experience building Sentinel automation with Logic Apps, along with PowerShell or Python scripting.
• Familiarity with Microsoft Security Copilot, Defender for Cloud, and Microsoft Purview.
• SC-401 (Information Security Administrator) or SC-100 (Cybersecurity Architect Expert).
• Vendor-neutral certifications such as CISSP.
• Bachelor's degree in cybersecurity, IT, or a related field, or equivalent experience.
