A day in the life of a Mobile Engineer

Our main focus is to provide a user friendly, secure mobile experience for our users. We work hard to implement useful, intelligent, and fun features to make the experience simple and powerful.

We take a measured approach to how we do things, so our processes usually involve working shoulder to shoulder with the business team, product people, designers, and fellow backend engineers to discuss how to best implement the next cool new feature.

We also make sure we have the right tool for the job, which means we’re constantly refactoring to improve our codebase and tooling to keep it up-to-date, and to utilise the latest technologies. That way we are able to take full advantage of all of their new features!

In addition to daily development life, we have a lot of freedom to develop ourselves and grow our knowledge. We’re free to tackle challenges in the best way we see fit, and to invest time in learning new mobile APIs and emerging technologies.
