Collaboration is key to how we operate across the business in this role, and you will work alongside product, design, and analytics teams to create the best tools for our users, helping them manage their cross-currency needs with ease whilst shaping the Wise Account offering.

Being a member of Mobile engineering, you are encouraged to influence other parts of the app, collaborate with 60+ other mobile engineers and help raise both the UX and code quality across all Wise customers. You’ll also be responsible for ensuring the solutions you build scale and fit well in order to achieve a high quality global product and collaborate often with your peers across other teams as well.

How We Work

At Account Mobile, we’re a team of iOS and Android engineers supporting all teams within the Consumer Account Squad. We drive the development of the app’s homepage and the features that help users manage and grow their money.

As a mobile engineer in Account Mobile, you'll be part of a core product team, working closely with a designer, product manager, and your fellow engineers. You will also have the chance to collaborate with other teams and contribute to broader technical initiatives across the company.

What will you be working on?

• Collaborate closely with product, design (UI), analytics, and other teams across the company to deliver impactful experiences to Wise users as part of a cross-functional team.
• Take responsibility for the overall health and quality of the iOS project.
• Collaborate with other iOS and Android engineers to ensure the iOS project remains current and leverages new technologies and best practices as well as consistency across platforms.

Qualifications

What do you need?

• Proven experience in building and deploying an app that delight customers
• Proficiency in Swift
• Familiarity with software architectural patterns like MVC, MVVM, or VIPER. (We use VIPER and MVVM but are open to exploring new approaches).
• Desire to write testable code
• Understanding of REST API design
• A strong product mindset and passion for user experience—you prioritise work with users in mind and make data-driven decisions to address user issues.
• Excellent communication skills and the ability to convey complex, technical concepts to non-technical audiences.
• Ability to both collaborate effectively with your team and solve problems independently and proactively.

Nice To Have

• Experience with SwiftUI, Structured Concurrency, or CI/CD pipelines (GitHub Actions)
• Familiarity with internationalisation patterns for apps serving many markets
• A fintech background — but absolutely not required
