Senior Systems Engineer (L3)

Our client is a managed IT services provider in Los Angeles. They support small businesses, mostly law firms and professional services. This is a genuine Tier 3 role. If a previous "L3" title covered work that was really Tier 2, this likely is not the right fit, and that is okay. We need someone who can take a problem from first report to resolution without anyone reviewing the work behind them. What you'll own You will handle the technical escalations that currently reach the COO. You will also lead our Microsoft and infrastructure projects end to end: tenant migrations, Intune and Autopilot rollouts, Exchange and SharePoint, server migrations, network builds, and security hardening. You will mentor our three junior technicians and lead the on-call rotation. Escalations come first, but they will not fill every day. When the queue is quiet, you will move to project work or jump in wherever the team is short, including lower-level tickets when that is what keeps clients moving. We are a small team, so everyone helps where help is needed. What we're looking for Deep, hands-on Intune experience is the requirement that matters most. Not "I have used Intune," but "I can design an Intune and Autopilot rollout from scratch": configuration profiles, compliance policies, app deployment, Conditional Access. You will also need strong Microsoft 365 (Exchange Online, SharePoint, Entra ID, mail flow, recovery), solid networking (Meraki, Fortigate, site-to-site VPN, VLAN design), and real security incident-response experience. We run a Mac fleet, so Jamf or Apple MDM experience is a plus, not a requirement. Perfectly fluent English is a must, written and spoken. You will deal directly with executive clients who hold extremely high expectations, so your communication has to hold up under that, clear and confident on a call and on the page. You work independently. You isolate a problem before you start changing things, you know when to escalate versus resolve, and you document as you go. Five years of MSP experience is a rough floor, but design ability matters more than the number. No degree required. 5+ years pf experience working in an MSP environment in the US (or equivalent MSP in LATAM) Proven expertise with Autopilot and Intune Expertise with Microsoft 365 (Exchange Online, SharePoint, Entra ID, mail flow, recovery), networking (Meraki, Fortigate, site-to-site VPN, VLAN design). Jamf or Apple MDM experience is a big plus. English level must be above a C1.
