Job Description

We are looking for a Database Reliability Engineer with a strong Software Development, or DevOps, background and a passion for Database Engineering and maintaining critical services to join Wise’s Database Reliability Engineering (DBRE) team.

The DBRE team are the owners and maintainers of the Wise database engine, which underpins almost every Wise user experience. Our mission is to superpower the Wise revolution with reliable, scalable and performant databases to store and recall data, and provide solutions and best practices within our organisation.

As an international Financial Services company, we also have the responsibility to keep our customers’ money and data safe. The DBRE team plays a critical role in this – by helping our Product Engineers work with Databases safely and ensure that best practices are always applied. To do this we work closely with the other teams building out the Data Platform, and with the wider Platform organisation to build out the required guardrails.
