Systems Administrator

Solaris Oilfield Infrastructure, LLC•Houston, TX

7d•Hybrid

About The Position

Solaris is growing quickly, and our physical footprint is growing with it. As additional data center and operating sites come online beyond our Houston headquarters, we need a Systems Administrator who is equally comfortable administering enterprise infrastructure remotely and standing in a rack aisle at a new site with a crimper in hand. This is a hands-on, multi-site role. You will own core Microsoft 365 and identity administration for the enterprise while serving as the traveling technical presence for our remote sites — build-outs, refreshes, escalations, and the on-the-ground work that cannot be done over a remote session. Travel of up to 50% is a core function of this position. Trips are typically scheduled in advance, but site-critical issues and go-live windows can require short-notice travel, occasional weekend work, and after-hours coverage. Candidates should be able and willing to sustain this travel level long-term.

Comfort with physical infrastructure work including racking equipment, running and terminating cable, and diagnosing hardware issues on site
Valid driver’s license and the ability to travel by air domestically
Ability to lift and move equipment weighing up to 50 pounds and to work in data center and light industrial environments
Exceptional communicator – direct and transparent, skilled problem-solver with proven success in building coalitions and avoiding conflicts
