Working at Higher One

Higher One is not your typical financial services company. Our environment is open – we do not have offices – not even for upper management. We typically work in casual attire, and while our focus on excellence is anything but casual, we know how to have fun, too. Teams have been known to plan surprise nerf gun attacks on other departments, we have paper airplane competitions and office chair races, and we have a foosball table in our casual lounge. The lounge is complete with couches and comfortable chairs – and is the site of some of our meetings as well as a place to relax. We work hard – and we have fun while we do it.
