Zentro is one of the fastest-growing internet service providers in the country, and we’re not about to stop there.

We’re putting the corporate giants on notice by providing residential and business customers with remarkably fast, exceptionally reliable internet service for less. And we’re doing it all with uncommonly responsive customer service and technical support — something the other guys can only manage in their dreams. Maybe.

READY TO BECOME A ZENTRO PRO?

Keeping internet connections up and running all day every day is kind of a big deal, and our people are proud to be doing it. Some might consider us the unsung heroes of the digital age. That’s what we think of ourselves anyway. Every person and every role here is important, and the positive energy you bring to work with you has tremendous value.

Zentro Pros come to work every day excited to make an impact. If you have an entrepreneurial spirit like we do, a strong work ethic, and a common-sense style to conducting business, there’s no doubt you’d fit right in. Zentro leadership also places great value on initiative, rewarding employees who exceed goals and expectations. So, if you’re a real go-getter, you’re definitely going to get noticed.

A COMFORTABLE PLACE TO DO YOUR BEST WORK

It’s no secret – happy people do better work. So we proudly provide a pleasant, highly functional work environment where our Zentro Pros can find their center and excel. Our headquarters is presently situated in Chicago’s burgeoning West Loop tech hub, surrounded by fast-growing technology companies of all kinds and sizes. We’re a short distance from public transportation, not to mention a growing variety of Michelin-rated restaurants, entertainment venues, and the Fulton Market District. With a job here, work is only the beginning.

A SOFT SPOT FOR THE PEOPLE WE SERVE

Zentro is proudly committed to playing an important role in the communities we serve. We’ve even partnered with large municipalities (like the City of Chicago) to provide free Wi-Fi to parks and beaches. It’s all about keeping people connected wherever they go. But, seriously, enough about us…we’re really excited to learn more about YOU!
