The Cash engineering team is responsible for building and maintaining the systems that make it all work.  Every one of our customers needs fast and reliable access to their accounts, and the Cash Availability engineering team is responsible for making sure that happens. We care about infrastructure that makes it easy to write software that is secure, efficient, and tested. This includes the feature flagging interface used by all of Cash Engineering, which we have deep focus on building out safety rails and improving user experience. We examine metrics to find and fix any problems that arise from a massively scaled app, and if those metrics don’t exist we build them. We take an active hand in incident response, both in responding quickly to incidents as well as owning the tooling to improve response. We’re a team of engineers with a very wide breadth of experience, and we frequently work in teams to tackle big problems.
