Database Reliability Engineer

Company Description

Wise is one the fastest growing companies in Europe and we’re on a mission: to make money without borders the new normal. We transferred over £118 billion in the Financial Year 2024 alone, and we’re growing. Fast.

Current banking systems don’t let us send, spend or receive money across borders easily. Or quickly. Or cheaply. 

So, we’re building a new one.

We need a Database Reliability Engineer to join our mission and help us build a global platform that’s scalable, reliable and secure. You’ll dive right into projects in Database Reliability Engineering spanning the breadth of Wise to deliver value for our customers.

Job Description

About the role

We are looking for a Database Reliability Engineer with experience in MariaDB/MySQL, 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.

DBREs work in very tight collaboration with the Database Platform team creating a blend of database engineering, dev-ops and software developers that apply sound engineering principles, operational discipline and mature software development and automation, specialising in databases (MariaDB, MongoDB, PostgreSQL and Redis in particular). In that capacity, DBREs bring database expertise to the Database Engineering group as well as to our engineering teams.

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.
