Our app is used by thousands of people every day—it’s a tool for them to do their job which is why we care a lot about not having any regressions in the app. 

As engineers, we have strong product ownership. It means we are part of product development from early designs to deployment and monitoring. This allows us to have a deep conversation with Design and Product teams about not only how we build things but also what we build.
