Systems Administrator (Engineer)
Overview
Slow down, we do things a little differently here at Seitel Systems and this job posting is no exception! Let’s get the basics out of the way in that we are growing and need to add more smart folks to our team, so this posting is for full-time position starting just as soon as we find the right person.
Please note, local candidates only. We will not accept applicants who don't live near the Puget Sound.
Key Points
IT Engineering for the long haul
Work Life balance
Hybrid environment: 3 days in, 2 days remote (local candidates only, please)
Profit sharing and strong benefits package offered upon conversion
Never heard of us? Well, if you were a small or medium-sized business located in Puget Sound you likely would have as we provide IT Engineering services to a whole lot of folks in all sorts of industries and our roots go back to 1990. No hardware sales, no software sales, just solid engineering work with a fantastic client service ethic. Seriously, we are over-the-top focused on doing great work for our Clients, and if they ever feel that our work wasn’t up to snuff then we don’t bill them for it. It’s as simple as that.
We operate on a hybrid model with a blend of working from home, onsite time at our Clients and time in our offices in Seattle and Tacoma. It is great to see everyone again, and we've resumed our lunchtime get togethers, late afternoon H^3 events (hosted happy hour) not to mention the in-office sodas, snacks, and monthly all-team breakfast meetings.
Also, important to know is that unlike the more prominent – and larger – technology firms here in Seattle and Tacoma, we have a strong commitment to work life balance. No crazy emails at 10:30 pm, and no crazy text messages at 10:35 pm asking why you haven’t responded to the email that was just sent.
Our HR team is not working 100 hours a week to get to the bottom of any employee issues, rather they're working hard during normal business hours with all of us to keep this a great place to work. The org chart is called a sketch, our HR manual says DON’T PANIC on the cover and the culture here is such that when folks land a job here, they stay for a long, long, time – and no, the doors aren’t locked.
On top of all of that we pay well, offer comprehensive benefits and are nicely profitable. Ah, and we make a point of sharing the profits with everyone here that helped make those possible in the first place - in fact, we are a 100% employee-owned company (ESOP). You will contribute to those profits with your efforts and expectations aligned with the work life balance mentioned above. We provide a 401k with a company contribution, medical/dental/vision coverage, short & long-term disability insurance, life insurance, transit passes, flexible holidays as well as vacation and sick leave.
Job Description
This position is with our Field Services Team, working with multiple Clients where you'll provide leadership and help integrate new technologies that get the most out of their IT investment.
Unlike a traditional IT gig where every day you work on the same stuff, likely from the same desk, this position will turbocharge your career giving you hands-on exposure to a wide variety of technologies across many different environments.
if you think you're ready to "run the show" then please read on to see if your skills are a great fit.
Our Engineers are expected to have the following qualities:

Earning an Azure or AWS certification before applying gives entry-level candidates a measurable edge in a market where cloud skills are a baseline expectation.
