Senior Software Developer for Cash Management Team

Wise is a global technology company, building the best way to move and manage the world's money. Min fees. Max ease. Full speed.

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

Our Cash Management team builds products that give banks flexibility in how they fund international payments, settle with Wise, and convert currencies. You will be working on solving concrete problems such as how a bank can lock in an exchange rate today and provide the funds later, or how it can send payments first and settle with Wise afterward.

We are looking for a senior engineer who enjoys understanding a customer's problem, designing a solution, and taking responsibility for how it performs in production. You will own solutions from problem to production, working with product managers and engineers to understand partner needs, shape the approach, and design, build, test, and operate backend services.

Responsibilities:

• 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., PostgreSQL) 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.

Qualifications:

• Hands-on experience building or making substantial contributions to large-scale distributed systems.
• Strong backend engineering experience, including relational databases, event-driven systems, and proficiency in an object-oriented language.
• A product mindset: you can explain the customer problems behind your work, why your solution matters, and how you assess whether it helps.
• The ability to take ownership with a high degree of autonomy, make progress through ambiguity, and involve others when their expertise is needed.
• Strong collaboration and communication skills.

Benefits:

• Starting salary: £87,000 - £111,000 + RSUs
• Wise Benefits
