The Role
Company Description

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.

Job Description

We are looking for an experienced Senior Software Engineer with a strong product and engineering mindset to join our Treasury team.

Our team is responsible for providing a real-time view of how much money is in Wise's various banking entities around the world, by responding to events that occur when people use Wise's products (customers and internal teams), and translating these events to actual and forecasted money movements. This data is used by trading teams to manage foreign exchange exposure risks and to ensure each entity has enough liquidity to support Wise's operations. These teams make trades in the order of 10s to 100s of millions of pounds based on our data, so it is very important that the data is correct and up to date. Our main challenges are around providing a reliable system at scale.

How we work

We operate on a strong belief in automation, programmatic implementation, and reusable design. We’re looking for people who can step back and think holistically about the ecosystem, but also follow through and help implement the design; drawing on the resources across the rest of the treasury tribe.

As we grow, sustaining our trajectory requires ongoing refinement and iteration of our services with a focus on availability, security, and user experience. We need a seasoned engineer who can dissect complex requirements and create elegant, impactful solutions, empowering our teams to advance our mission with agility and confidence.

What will you be working on?

You will be working on initiatives to ensure that the ledger continues to provide accurate and timely data as the company scales.

Qualifications

We acknowledge that engineers continuously evolve their skillsets, and we are committed to supporting your growth. However, we are looking for candidates who can bring these core skills to the table:

  • Extensive experience and proven track record in software engineering, ideally with a focus on financial systems or markets (not hard requirement)

  • Exceptional product mindset, able to balance customer-centric and data-driven approaches 

  • Strong leadership skills with the ability to influence cross-functional teams

  • Expertise in messaging systems such as Kafka

  • Proficiency in Java and Spring Boot is highly valued

  • Experience with both relational and non-relational database design

  • Commitment to continuous improvement and knowledge sharing

  • Advocating for best practices in code quality, continuous delivery, and robust code reviews

The successful candidate will onboard rapidly, bringing insights to help refine the team vision while contributing to the potent impact our products have on customers' lives.
