Job description:

About Us

We’re a high-speed MSSP that’s redefining what IT support looks like for modern businesses. We bring calm to chaos, secure networks like pros, and help our clients sleep at night knowing their tech stack won’t betray them.

We’re not here to “maintain the status quo.” We’re here to automate, optimize, and protect—before threats ever become tickets. Our clients trust us with their infrastructure and their security. And we deliver.

We're looking for a Junior Systems Administrator who’s comfortable in the trenches, but has their sights set on cybersecurity and system ops mastery. If you're ready to grow into infrastructure, SecOps, or cloud admin work—and you're not afraid of doing the hard stuff first—this role was built for you.

What You'll Be Doing

Tackle L2/L3 tickets and escalated tech issues (servers, networks, cloud, endpoints)

Administer and secure:

Windows Server / AD / Group Policy
Microsoft 365 / Azure AD / Entra ID / Conditional Access
Intune, Defender EDR/XDR, and cloud-based endpoint protections
Work with tools like NinjaOne, Halo PSA, Huntress, SentinelOne, and CrowdStrike
Help implement security remediations and close vulnerabilities
Onboard new clients, run baseline security checks, and build documentation that makes sense
Automate where you can, script when you must (PowerShell experience preferred)
Stay in sync with our team and our clients—this isn’t a solo ride

Who We're Looking For

3+ years of hands-on IT support or sysadmin experience (MSP background is a big plus)
Strong grasp of Windows environments, cloud administration, and endpoint/network security
A baseline understanding of EDR/XDR/MDR tools—and curiosity to dive deeper
Experience with RMM/PSA tools and patching workflows (NinjaOne, Halo, etc.)
Ability to communicate clearly and confidently—with clients and teammates
Someone who doesn't wait to be told what to do—you see it, you solve it
Most importantly: You want to be part of something growing and meaningful—not just punch the clock

Bonus Points For:

Experience with compliance (HIPAA, CMMC, CIS frameworks)
Familiarity with scripting (PowerShell, Bash, etc.)
AI Automation Wizard
Exposure to Azure environments, Defender portal, or cloud automation
A personal home lab

What You Get

Profit-sharing & performance bonuses — the harder we crush it, the more you earn
Paid certs & access to hands-on labs (Microsoft, SentinelOne, CrowdStrike, etc.)
Clear career path into infrastructure, cybersecurity, or project leadership
Autonomy and mentorship (we don’t micromanage—we support and expect results)
A fast-moving, no-BS, zero-drama environment where your work actually matters

Bonus points if you include:

A walkthrough of a lab or project you’ve built
A script you wrote to make your life easier
Or a short video telling us why this role is you
