Job description

Outsourcing Advantage is a boutique BPO provider specializing in back-office and operational support for U.S.-based businesses. We are seeking an experienced L2/L3 Systems Engineer with a strong background in Managed Services Providers (MSP) environments to join our team. The ideal candidate will have hands‑on experience supporting multiple clients, troubleshooting complex infrastructure issues, and managing Microsoft-based environments.

This role requires a highly technical, organized, and proactive professional who can independently diagnose issues, research solutions, and deliver exceptional support across diverse client environments.

Responsibilities

• Provide advanced Level 2 and Level 3 technical support for multiple client environments.
• Troubleshoot and resolve complex issues involving Microsoft 365, Azure, networking, servers, endpoints, and infrastructure.
• Manage and support Microsoft cloud technologies, including Entra ID (Azure AD), Exchange Online, SharePoint, and Intune.
• Administer and troubleshoot Windows Server environments, including Active Directory, Domain Controllers, Group Policy, and directory synchronization.
• Configure, maintain, and troubleshoot network infrastructure, including firewalls, VPNs, content filtering, and security solutions.
• Support virtualization environments, including hypervisors and virtual machines.
• Assist with Azure infrastructure, including Azure Virtual Machines and Azure Virtual Desktop (AVD).
• Manage backup solutions, perform troubleshooting, and ensure successful recovery processes.
• Document service call notes, technical resolutions, system configurations, diagrams, and internal procedures.
• Create and maintain technical documentation, checklists, and knowledge base articles.
• Research and implement new technologies, tools, and best practices to improve client environments.
• Communicate effectively with clients, team members, vendors, and external stakeholders.
• Prioritize and manage multiple tickets while meeting service-level agreements (SLAs).
