Senior Software Engineer II - Cash Management

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 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.

Responsibilities:

• 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. Explain tradeoffs clearly and balance delivery time, reliability and maintainability.
• Build across system boundaries. Work with other teams to agree clear interfaces and understand how changes affect the wider payment journey.
• Improve the systems you operate. 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.

Requirements:

• 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.

Nice to have:

• Java, Spring Boot, Kafka or PostgreSQL.
• Payments, financial technology, funding, settlement or foreign exchange.
• Using product metrics and data to understand customer behaviour and guide decisions.
