Our mission is to always give more than we get by creating value and having a positive impact at every turn.
We are in an exciting and evolving industry with significant opportunities ahead. We love what we do, and we are growing!

Demonstrating the excellence of our team, Mainstay has also won “Best of Business” for Managed IT Services, the Torch Award for Marketplace Ethics, and we’ve made the Inc. 5000 List for fastest growing companies several times.
Our clients typically have a staff of 15-300 happy professionals and look to us for technology and security leadership, guidance, and service delivery. We provide the service of a full IT department and a full Information Security/Compliance department.
The role you’ve been looking for is here! Mainstay Technologies is looking for a Systems Administrator (SA) that is passionate about helping people, thrives when flexing between varied tasks, leverages a broad technical foundation, and enjoys evaluating new technologies.

As the SA for dedicated clients, you’ll lead essential elements of the service delivery our clients praise. We provide the service of an entire secure IT department and you’ll engage intimately with our clients to deliver on our commitment to excellence. You’re responsible for managing ongoing client relationships, participating in leading technology improvements, overseeing proactive measures, implementing projects (with the support of specialist engineers), and exercising a high degree of “ownership” over the clients’ environment. This is an integral role, working closely with other team members for comprehensive service delivery.
But how will you keep up with all there is to know in the evolving world of IT? We provide continuous training opportunities and team support, and there are multiple opportunities for growth, training, and specialization. The experience gained is significant!

  • Addressing some reactive desktop, server, and network issues, assisting the whole team with what needs to be done
  • Participating or leading client projects, implementing new technologies such as servers, firewalls, applications, and more
