You and the Role

Working in and across self-organised mobile engineering teams is a natural part of our outcome-based culture.

• Jenkins & Git, driving automated continuous integration and delivery pipelines

And meet most of the following:

• You are a capable senior engineer, passionate about guiding and growing junior engineers towards appropriate target architectures
• You have diverse technical experience, perhaps with a background spanning backend engineering to mobile ecosystems
• You maintain a strong questioning (and diplomatic!) mindset, relentlessly driving modern engineering practices across mobile communities of practice
• You write well-factored, well-tested code and act as an advocate for quality using practices like Pair Programming, TDD, and BDD
• You can effectively communicate across engineering teams to maximize inner-sourcing opportunities and reduce waste
• You enjoy being a helpful, approachable, and inquisitive problem-solver who thrives in delivering frequent, high-quality releases within a complex regulated environment
• You enjoy hybrid working, with Tuesday, Wednesday, and Thursday spent collaborating in our bright offices

What you should know about how we recruit

We pride ourselves on hiring the best people, not the same people. Building diverse and inclusive teams is the right thing to do and the smart thing to do. We want to work with top talent: whoever you are, whatever you look like, wherever you come from. We know it’s about what you do, not just what you say. That’s why we make our recruitment process fair and accessible.

We value diversity, inclusion and belonging at our core. We empower our associates to do great work by creating an inclusive culture—one that values diverse perspectives, fosters collaboration and encourages innovative ideas—and a place where associates of all backgrounds can thrive by bringing their most authentic selves to work. We call this our Culture of Belonging, and it rests at the heart of our business.

Our associate-led Business Resource Groups were created to help support our diverse population and include over 10 groups across our offices. Because each Business Resource Group is as unique as the population it serves, they offer a range of activities, networking opportunities, special events and learning programmes to associates.

Capital One is committed to diversity in the workplace.
