San Diego, CA

Job description

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.

What You’ll Actually Do

Own and support Microsoft-heavy environments: AD, Azure AD, Exchange Online, Intune (a must), SharePoint, Teams, Windows Servers

Handle day-to-day support: hardware, software, networking, etc

Maintain and troubleshoot VMware infrastructure

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

VMware proficiency

Solid networking fundamentals (VLANs, firewalls, wireless)

Clear communicator with users and decision-makers

Organized, self-managed, and flexible

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.
