InnerSourcing is a cultural shift in how we build software at American Express. It recognises that our source code belongs to the whole organisation, not individual teams. By opening our codebases, every engineer at Amex has the opportunity to contribute to any project.

The successful applicant will be experienced software engineers with a curiosity for diving into new codebases and working in a variety of technologies to power and protect the growth of our International Card Services business.

When considering whether someone is a great fit for our team, we won’t focus solely on languages used or experience, but their ability to think creatively, approach problems with an intelligent mindset, and above all their passion to Make Stuff Happen! We are looking for good communicators who are comfortable with regular context switching, reaching out to other teams and working through problems in a collaborative way.

As part of our diverse tech team, you will design, code and ship software that makes us an essential part of our customers’ digital lives.
