Senior iOS Engineer II

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 help create an entirely new network for the world's money.

About the role

The High Volume teams within our Send squad focus on customers who send large amounts of money internationally—whether they’re individuals buying property abroad, managing wealth across countries, or businesses making significant cross‑currency payments. Our mission is to make international payments seamless for customers sending large amounts, whether that’s a £500k property purchase or a company’s monthly payroll across borders.

You will work across two closely aligned teams:

• Send High Volume Team – Focused on the experience of customers sending large amounts, ensuring transparent pricing, clear limits, and seamless coverage.
• Business Send Team – Builds the best‑in‑class payment experience for businesses, making sending money convenient and efficient.

For you, this means an incredible opportunity for impact and growth. You will be at the forefront of developing a critical part of our high‑volume features on mobile, an area with huge scope and exciting challenges to solve.

What you will be working on

In this role, you’ll own the iOS experience across both teams, ensuring customers can benefit from Wise’s high‑volume features on the go. Whether they’re approving a transfer from an airport, paying hundreds of employees, or buying a property in Italy, we want these experiences to feel seamless on mobile as they do on desktop. We’re looking for an autonomous and proactive iOS Engineer who thrives on taking ownership of their work. This is far more than a coding role; you’ll be a key product partner for both teams, challenging our thinking and shaping the product roadmap. You’ll be involved from ideation and definition through to building and shipping new, high‑impact features from the ground up. As a member of Mobile Engineering, you’ll also influence other parts of the app, collaborate with 60+ fellow mobile engineers, and help raise UX and code quality across all Wise customers. You’ll be responsible for ensuring the solutions you build scale and fit well to achieve a high‑quality global product, collaborating often with peers across other teams.

Qualifications

• Proven experience building and deploying an app that delights customers.
• Strong proficiency in Swift.
• Familiarity with software architectural patterns such as 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.
• Strong product mindset and passion for user experience, prioritising work that addresses user needs and making data‑driven decisions.
• Excellent communication skills, able to convey complex technical concepts to non‑technical audiences.
• Ability to collaborate effectively within a team, as well as independently and proactively solve problems.

You may also have

• Experience with SwiftUI, Structured Concurrency and CI/CD pipelines (GitHub Actions) would be great.
• Background in fintech (a plus, but not required).

We understand it is uncommon for a candidate to have everything listed; we support learning new skills with us.
