System Administrator II (Security Focus)

JMARK is an IT managed services provider headquartered in Springfield, Missouri, with a second office in Tulsa, Oklahoma, and numerous full-time remote employees spread throughout the country. The reason JMARK is a "best" place to work can be summed up in one word: culture. Nurturing a respectful, supportive, dynamic, spirited culture among the more than 125 individuals that make up JMARK is a point of passion for CEO Thomas Douglas. It matters so much to him that every decision made regarding JMARK is run through the filter of how it will impact the culture at large—as well as every employee on an individual level.
This dedication to creating a positive environment has been instilled in every leader at any level—including the board of directors—and passed down to every employee in the company. From the first moment one walks in the door at JMARK, it is clear that this is a true family made up of teammates who care for one another, cheer each other on, and thrive on coming together to achieve greater things together than could ever be done alone. In fact, this feeling of fellowship is so strong that it transcends the distances between teammates working from home or in different locations.  The words "People First" are in our slogan, and everything that happens at JMARK leads back to that phrase.
