Network Performance Manager Jobs in Chicago, IL (NOW HIRING)

Impact exists because a small group of industry leaders believed companies in our space were doing it wrong. Many prioritized margins while the people doing the work and the clients relying on it became an afterthought. Impact was built differently: invest in great people, trust them to do great work, and deliver the kind of service clients remember. That approach helped us grow from a small office technology company into a national managed services provider, while remaining privately owned and people-first.

What makes Impact special is that growth has never come at the expense of the values that got us here. We continue to reinvest in our people, our capabilities, and the opportunities ahead so employees can grow alongside the business. We’ve built something special, but we’re far from finished. The people who join Impact now will help define what comes next.
