Job description

We're looking for a hands-on senior MSP engineer who can independently own complex escalations, diagnose across infrastructure, Microsoft 365, networking and endpoints, lead significant technical change, and raise the capability of the engineers around them.

At Benchmark 365, you'll work across many customer environments on behalf of our MSP partners. If you enjoy variety, difficult technical problems and being the person people turn to when nobody else has the answer, this role is for you.

The kind of problems you'll own

Our L3 engineers handle work such as:

• Troubleshooting complex Azure Virtual Desktop, Entra ID and Conditional Access issues
• Designing and delivering multi-site networks across firewalls, VLANs and voice/SIP services
• Leading root-cause investigations into recurring RDS, server and business-critical application problems
• Building automation using Intune and Entra ID where native vendor integrations fall short
• Taking ownership of complex, long-running infrastructure problems and engineering permanent fixes

What you'll do

• Own complex incidents end to end as the final technical escalation point
• Diagnose issues across Microsoft 365, Entra ID, Windows Server, Active Directory, endpoints, networks, firewalls, VPNs, virtualisation and backup
• Lead technical responses to business-critical and security incidents
• Manage vendor support cases while retaining ownership of the outcome
• Take technical ownership of migrations, implementations, upgrades and remediation projects
• Present options and recommendations where decisions involve commercial considerations or risk
• Coach L1 and L2 engineers through peer review, knowledge transfer and runbooks

What you must bring

• Recent hands-on experience in an MSP, IT services or multi-customer environment. This is non-negotiable. Internal-IT-only experience will not be enough for this role.
• 5+ years of systems, infrastructure or cloud engineering experience, including time as the final escalation point
• Advanced troubleshooting and root-cause analysis skills
• Strong Microsoft 365, Entra ID, Windows Server, Active Directory, Group Policy, DNS and DHCP skills
• Solid networking knowledge across TCP/IP, VLANs, routing, switching, firewalls and VPNs
• Hands-on delivery of migrations, implementations or significant infrastructure change
• Clear professional English and the ability to explain technical impact, risk and options
• The ability to work consistently from our Cebu office

It would be great if you also bring

Experience with Intune, Autopilot, Defender, Conditional Access, Azure, VMware or Hyper-V, backup and disaster recovery, PowerShell, Microsoft Graph, APIs or Power Automate. Experience mentoring engineers and relevant industry certifications are also valuable.

This role is for you if

• You'd rather fix the root cause than simply close the ticket
• You enjoy being the person others rely on when nobody else has the answer
• You like working across different customers, environments and technologies
• You get satisfaction from making both systems and the engineers around you better

This role is not for you if

• You want to work purely on projects or within one internal IT environment
• You prefer to hand complex problems on rather than see them through
• You're looking for a remote or hybrid role

How we'll invest in you

• Funded certifications
• Exposure to a wide range of customer environments and technologies
