Job description

Location: Local WFH - Orange County / Los Angeles

Onsite: Typically only a couple times per month or less

For this opportunity, you'll be joining a long-established Southern California Managed Service Provider supporting legal firms and SMB clients across the region. This is a Microsoft-focused MSP with an extremely stable client base and strong employee retention, including team members who have been with the organization for 10-20+ years.

This is a local work-from-home Level 3 / Systems Engineer position with very limited onsite requirements. You'll serve as the senior escalation resource for complex infrastructure issues while also mentoring L1/L2 technicians and helping improve documentation and processes. This is not a high-pressure "bill every minute" MSP environment - productivity and client satisfaction matter, but the company places a strong emphasis on work-life balance and family time.

What You'll Be Doing

• Serve as the Level 3 escalation point for complex technical issues
• Troubleshoot and resolve server, identity, networking, security, cloud, and endpoint issues
• Support and troubleshoot Azure Virtual Desktop (AVD)
• Handle AVD user/session issues, image updates, policies, scaling, and application delivery
• Support Windows Server and Active Directory environments
• Troubleshoot DNS, DHCP, TCP/IP, VPNs and SSL VPNs
• Support Microsoft 365 and Exchange Online
• Diagnose VMware and virtualization issues
• Troubleshoot switching, VLANs, firewalls and network connectivity
• Mentor L1/L2 technicians on troubleshooting and escalation practices
• Build and maintain runbooks, SOPs and technical documentation
• Work alongside senior engineers on infrastructure and cloud initiatives
• Communicate directly with clients and own issues through resolution

Technical Background

We're looking for someone with:

• 3-5+ years of MSP experience
• Windows Server
• Active Directory
• DNS / DHCP
• Microsoft 365 / Exchange Online
• RDP
• TCP/IP
• VPN / SSL VPN
• VMware vSphere
• L2/L3 networking
• VLANs
• SonicWall firewalls
• Strong troubleshooting/root-cause analysis
• Strong client-facing communication
• Ability to independently own complex escalations

Experience with MSP platforms such as ConnectWise Manage, NinjaRMM and IT Glue is highly valuable.

Additional Technology Exposure

The environment also includes:

• HPE Servers
• Nimble SAN / MSA
• SentinelOne
• Acronis
• Legal-industry applications
• Azure architecture and design

Who This Makes Sense For

This is a strong opportunity for an experienced MSP Systems Engineer, Senior Systems Administrator, or Level 3 Engineer who enjoys being the person other technicians turn to when they cannot solve an issue.

You'll still be hands-on technically, but you'll also have the opportunity to mentor junior engineers, improve internal processes and documentation, work with Azure/AVD, and participate in higher-level infrastructure projects.
