Company Description

Min fees. Max ease. Full speed.

Whether people and businesses are sending money to another country, spending abroad, or making and receiving international payments, Wise is on a mission to make their lives easier and save them money.

As part of our team, you will be helping us create an entirely new network for the world's money.
For everyone, everywhere.

More about our mission and what we offer.

Job 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.

About the role

We are looking for a Database Reliability Engineer with 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.

Who we are looking for

Here's what we're looking for in a software engineer working in the Database Reliability Engineering team, but don't be intimidated – if you're passionate about learning and interested in what we do, we'd love to hear from you.

We value a balance between robust engineering skills and a good understanding of database technologies. Ideally, you'll have experience in both areas, but if you’re strong in one and eager to learn the other, you could be a great fit too.

Engineering Skills:

• Extensive experience designing, implementing, and testing solutions following software engineering principles.

• Strong Programming skills in an object-oriented language (Python or Go is a plus).

• Strong Experience with infrastructure automation and configuration management tools such as Chef, Ansible, Puppet, or Terraform.

Cloud Experience:

• Familiarity with cloud technologies, preferably AWS (experience with Aurora and other AWS managed services is beneficial).

Nice to have:

• Experience working with relational databases like MariaDB/MySQL or PostgreSQL in production environments.

• Familiarity with managing databases in high-demand, 24/7 environments

• Good knowledge of SQL and PL/pgSQL—debugging and optimization skills are a big plus.

• Understanding of database internals and performance tuning for MariaDB/MySQL or PostgreSQL.

• Knowledge of backup and recovery processes.

• Have experience working in a distributed production environment.

• Experience with MongoDB (or any other NoSQL technologies)

• Experience in building self-service tooling that helps engineers, analysts or data scientists do their job more efficiently

• Knowledge/interest in payment platforms, foreign exchange & highly complex systems

• Be a customer of Wise.
