Capital One

You probably think of Capital One as a credit card provider. But in many ways, we’re as much of a technology company as a finance company. And that’s why Software Engineering is pivotal to our success.

This is where you can create game-changing new software for our customers. Build new solutions. Tackle all sorts of business challenges. Meaning we have to be super agile. Which makes Tech at Capital One an exciting place to work. Get ready for design thinking, open source software, public cloud, API’s, a lean start-up mind-set, and agile framework. You’ll get ownership over big projects that will make a real difference to our customers. And we’ll give you all the tools you need so you can learn and progress along the way. It’s a win win.

Open source culture.

We use a wide variety of open source tools and technologies to develop public cloud solutions. Different teams have different needs and different problems to solve.

Open source isn’t just a technology preference; it also represents our culture. Our engineers are encouraged to share their thinking, lessons, and solutions both internally and externally.

You’ll get to share this open culture with your tribe. Our four engineering tribes are made up of small teams that have freedom over design, development and deploying applications into the cloud.

The best part of my job is being able to give my team the space and time to develop in a way in which suits them.
