• Wise# Senior Software Engineer II - Cash Management London, GBEngineering Hybridposted today### About the team Banks need flexibility in how they fund international payments, settle with Wise and convert currencies.

Our Cash Management team builds the products that give them that control and make Wise work for more partners and their customers.

The problems are concrete.

How can a bank lock in an exchange rate today and provide the funds later?

How can it send payments first and settle with Wise afterward?

We build the capabilities behind those choices, helping partners manage their cash around the needs of their business.

We’re a small, growing team developing new products in a domain with plenty to learn and shape.

You’ll have a meaningful say in how we solve customer problems, design our systems and maintain engineering quality as we grow.

The work combines product development with the challenge of building dependable services that move money across systems.

You’ll work closely with product managers, partner banks and engineers across Wise whose systems handle accounts, incoming payments and liquidity.

Together, you’ll understand partner needs, agree how those systems fit together and turn complex requirements into practical products.### About the role We’re looking for a Senior Product Engineer who enjoys understanding a customer’s problem, designing a solution and taking responsibility for how it performs in production.

This is a hands-on role with substantial ownership.

You’ll have the autonomy to move work forward, alongside colleagues who contribute through shared design, reviews and pairing.### You will* Own solutions from problem to production.

Work with product managers and engineers to understand partner needs, shape the approach, and design, build, test and operate backend services.* Make thoughtful technical decisions.

Strengthen testing and observability, diagnose production issues, and use what you learn to make services more dependable.* Help the team succeed.

Contribute across workstreams, share domain knowledge and help other engineers grow through reviews, pairing and mentoring.

Our backend stack includes Java, Spring Boot, Kafka and Postgre SQL.

You’ll deepen your understanding of funding, settlement and currency conversion, using that knowledge to make better product and engineering decisions.

As the team’s scope grows, there will be opportunities to take on broader technical ownership and influence how we build.

What will you be doing?* Design, develop, and maintain highly scalable services in Java and Spring Boot within a microservices architecture.* Apply domain-driven design to build robust, scalable solutions.* Lead development efforts in event-driven architectures using Kafka or similar messaging systems.* Architect, design, and optimise relational databases (e. g., Postgre SQL) to ensure performance and scalability.* Collaborate with cross-functional teams to support partner integrations and expand the Wise payment platform globally.* Participate in code reviews, champion best coding practices and mentor junior engineers.
