SENIOR SYSTEMS ENGINEER

Location: Fort Collins, CO

WHO WE ARE

Open Approach is a values-driven, client-focused IT services company based in Burlington, Vermont. We deliver exceptional managed technology and phenomenal client support to organizations across New England and beyond. Our focus is on long-term partnerships built on trust, transparency, and shared success, not sales quotas.

We earn our client's business every month by staying relentlessly focused on their success. From the very first interaction to ongoing evolution, we aim to provide seamless experiences grounded in understanding, integrity, and practical solutions. We believe in making thoughtful, informed decisions and creating a lasting impact instead of quick fixes. This translates into long-term relationships with our clients that are rewarding on many levels.

At our core, we value equity, humility, excellence, accountability, innovation, and openness. These guide everything we do, from how we collaborate internally to how we support clients through complex technical challenges.

We are continually refining our team, enhancing our capabilities, and investing in talent to drive forward meaningful change. We embrace candid feedback, own our outcomes, and strive to improve every day. If that sounds like the kind of company you want to grow with, we would love to hear from you.

THE IDEAL CANDIDATE

We are looking for an enthusiastic, empathetic, personable, self-driven individual, undeterred by the challenges that come with working in a small but growing tech company. Day-to-day tasks can vary significantly, but your primary focus will be on the execution of complex technical projects for our clients. The variety of project work and design/architecture statement of work generation is vast. If you're enthusiastic about architecting and implementing highly technical solutions and have the people skills to be strategic with our clients, then this could be the fit for you!

A successful candidate for this position will, above all, closely reflect the values that we have built this company upon: honesty, integrity, and an ambition to continually improve every aspect of our work.
