What we do.

Cardinal, a Visa solution, is a global leader in authenticating digital transactions. We work every day to make the digital shopping experience safe, rewarding, and engaging. We're a global leader not only because of what we do, but because of who we are. Our team represents the best of the best. We work in a way that suits our people, their lifestyles, work styles, and individuality. We work hard as a team to collectively meet - and exceed - goals and consider each other family. We are one of the leading fintech companies in Northeast OH with teams locally and around the world working remotely. We are proud of what we do and how we do it.

Come join us


When you work with us, you get the best of two worlds. Cardinal is a small company, with a welcoming, family-like atmosphere. But as a Visa solution, we offer the world-class resources and benefits of a global company. As companies with a worldwide customer base, both Cardinal and Visa realize the benefits of having a diverse employee base, both for our products and customer service. We believe in promoting a diverse and inclusive workplace. Our employees come with different backgrounds and experiences, resulting in many different approaches that are part of our success. We are committed to empowering each and every one of our over 250 (and growing) employees. We show respect to others and believe in fair and equal treatment. We are dedicated to continuous improvement in all that we do. We use Lean and Agile principles and rituals as the framework for achieving that improvement. To achieve these goals, we need accomplished and ambitious people - people that recognize the value that comes with the varying perspectives, and the cultural awareness that comes with our diversity. What we are looking for could be someone just like you.
