Hansel Auto Group is looking for a Systems Administrator to help run and improve the technology that our dealerships depend on every day. Our IT team's mission is to empower Hansel employees to succeed with innovative tools, quality support, and expert leadership — and this role sits right at the center of that.

You willownthe day-to-day health of our network, servers, and core systems: keeping them available and secure, spotting problems before our users do, and steadily standardizing how things are built so the environment gets cleaner every quarter. You will also be a technical anchor for our help desk team, stepping in on the harder tickets and mentoring our junior technicians as they grow.

This is a hands‑on job with real ownership. If you like fixing root causes instead of symptoms, writing down how things work, and being the person others trust to get it right, you will do well here.

Maintain and administer our networks, servers, systems, and hardware across all locations.

Plan, coordinate, and implement security measures that protect company data, systems, and devices.

Monitor our infrastructure proactively — find and resolve issues before they become outages.

Troubleshoot and solve problems at the root, and recommend the hardware or software needed to do it properly.

Provide Tier 2 and Tier 3 support to end users by ticket, phone, and in person.

Jump in and help the help desk team clear tickets when the queue gets heavy.

Mentor our junior IT staff — share what you know and help them build real careers in IT.

Create and maintain clear documentation so the next person can pick up where you left off.

Build repeatable processes and standards so IT service is consistent no matter who delivers it.

Lead projects from start to finish, both on your own and as part of the team.

You are genuinely interested in technology. You are the one who fixes your family's computers, and you probably watch tech videos for fun.

You get real satisfaction out of helping people, including people who are not technical.

You adapt well when technology and priorities shift, which in a dealership group they do.

You take the work seriously without taking yourself too seriously, and you can receive direct feedback.

You can move quickly and keep several things going at once without dropping any of them.

You do what you say you will do — our co-workers trust IT to get it right.

At least four years of related IT experience, including hands‑on network and server administration.

High school diploma or equivalent. Relevant certifications (CompTIA, Microsoft, Cisco/Meraki) are a plus.

Demonstrated ability to troubleshoot effectively — gathering information, isolating causes, and resolving end-user issues.

Strong written and verbal English communication skills. Spanish is a significant plus, butnot required.
