Be the Escalation Point Everyone Relies On.

When standard fixes fail, your colleagues look to you.

Rosen Enterprises, LLC is looking for an L3 Senior MSP Engineer to take charge of complex escalations, infrastructure troubleshooting, root cause analysis, and projects for fast-growing U.S.-based MSPs.

This is a true senior position, not a helpdesk job with a bigger title. You'll troubleshoot, design, deploy, document, and carry complex technical work all the way through.

Prior MSP experience is a must.

Experience Required

3+ years of hands-on MSP experience, including:

Supporting multiple clients and varied infrastructures
Handling high ticket volumes in RMM and PSA platforms
Following escalation procedures and meeting SLAs
Communicating directly with clients
Managing several technical priorities at once

Resolving advanced L2/L3 escalations and performing root cause analysis
Diagnosing and resolving server and network infrastructure issues
Leading Microsoft 365 migrations (email, tenant, SharePoint, OneDrive)
Administering Azure and AWS environments
Managing Group Policy, server migrations (including P2V), and hypervisors
Configuring RMM, monitoring, patching, and automated deployments
Writing advanced scripts and automations
Handling VLANs, routing, firewalls, and VPNs
Setting up MFA and SSO
Delivering network and infrastructure projects
Coaching L1/L2 technicians

Work Setup

Onsite in Tayabas City, Quezon Province for the first 6 months
Strong performance may open the door to a remote setup afterward
Working hours aligned to your assigned U.S.-based MSP

What We’re Looking For

3+ years of hands-on MSP experience
Advanced troubleshooting skills
Proven ability to resolve server and network infrastructure issues
Strong PSA and RMM knowledge
Proven ownership of complex escalated tickets
Microsoft 365, Azure, networking, firewall, and server administration experience
Excellent written and spoken English, with clear documentation habits
Ability to explain technical issues in plain terms
Able to work onsite in Tayabas City, Quezon Province for the first 6 months

Nice to have
