Data is fundamental to how Capital One operates, and it is vital that the data we have is available to those who need it quickly, clearly and without barriers. By allowing our data scientists and owners to quickly review, analyse and dive into the data we collect – as we collect it – we allow them to provide not only great service to our customers, but also great tools and experiences to everyone within Capital One.

Developers in this role will have the opportunity to work with a wide range of technologies and with a variety of different teams to provide them with the tools, pipelines, scripts and applications to allow them to gain insights into the collected data as and when they need it.

The key requirement is an individual who is comfortable with a number of different programming languages and enjoys working alongside a number of different groups to help achieve their goals in a data-rich and fast moving development environment.
