Looking for a Senior Systems Administrator (Microsoft Platforms) who thrives in both worlds: deeply technical *and* people-savvy. You’ll manage infrastructure, lead projects, support users, and handle shifting priorities across multiple clients — all while keeping communication clear and expectations aligned. This is a 1099 contractor role, and yes, that’s a smart move if you know what you’re doing.

W-9 Isn’t a Downgrade — It’s Freedom (If You Know How to Use It) - up to $10k/mo

Degrees and Certs? Nice, but Not Required

Doesn't matter where (or if) you went to school. The knowledge is everywhere now — GPT, YouTube, Google. What matters is that you know how to solve problems, find answers fast, and get things done.We don't expect you to memorize every command — we expect you to know how to look it up and execute confidently.

What You’ll Actually Do

  • Own and support Microsoft-heavy environments: AD, Azure AD, Exchange Online, Intune (a must), SharePoint, Teams, Windows Server
  • Handle day-to-day support: hardware, software, networking, etc
  • Maintain and troubleshoot VMware infrastructure
  • Manage backups (Veeam, Acronis, Datto) and run test restores
  • Configure and support firewalls (Sophos, SonicWall), VPNs, routing
  • Troubleshoot LAN/WAN infrastructure: DNS, DHCP, VLANs, switches, Wi-Fi
  • Implement security controls: MFA, Conditional Access, Defender
  • Lead projects: migrations, onboarding, upgrades, cleanups
  • Write clean documentation so others aren’t guessing
  • Manage multiple clients and competing priorities without losing your cool

What We Are Looking For

  • 7+ years in Microsoft environments
  • Experience supporting multiple clients (MSP strongly preferred)
  • Deep knowledge of Microsoft 365, Azure AD, Windows Server, Intune
  • VMware proficiency
  • Solid networking fundamentals (VLANs, firewalls, wireless)
  • Clear communicator with users and decision-makers
  • Organized, self-managed, and flexible
  • Valid driver’s license and reliable car — you’ll be onsite regularly

The Details

  • 1099 contractor – no benefits, but flexibility and up to $10k/month
  • 10–40 hours/week, mostly during business hours
  • Onsite work required — SoCal-based clients
  • Long-term engagement for the right person
  • Must Reside in the Irvine area - no relocation or remote

If you’re great with tech *and* people — and want freedom, not micromanagement — reach out.
