Senior Backend Engineer

Wise is a global technology company, building the best way to move and manage the world's money.

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.

The team you'll be working with: Swift - Global Expansion

The Global Expansion team's mission is to open new routes where Wise customers can't send money today - ultimately allowing remittence to any beneficiary around the world. The focus is on coverage; opening exotic currencies and countries in bulk in an efficient, scalable way.

This includes utilising Swift - which is the "traditional" way of sending money internationally, and used by Wise to provide coverage in some special use-cases, like sending USD outside the US. Building a fast, predictable money sending product using Swift is an exciting challenge, and part of the team's scope. But Swift and correspondent banking is only one out of many ways the team is considering to provide global coverage, and we are free to use any means to reach yet unreached regions.

Our technology stack includes Java, Kotlin, Kafka messaging and relational databases, but also graphs and machine learning. We work on a daily basis with MT and ISO20022 payment files, Swift GPI, and integrate with PSP APIs.
