Senior iOS Engineer II
iOS Engineer (Send High Volume) – Wise
About Wise
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 internationally, spending abroad, or making/receiving international payments, Wise is on a mission to make their lives easier and save them money.
As part of our team, you’ll help build an entirely new network for the world’s money – for everyone, everywhere.
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, from £500k property purchases to monthly payroll across borders.
You’ll Work Across Two Closely Aligned Teams
- Send High Volume Team – Ensuring transparent pricing, clear limits, and seamless coverage for customers sending large amounts.
- Business Send Team – Building the best-in-class payment experience for businesses by making transactions easy and efficient.
For you, this means an unprecedented opportunity to drive impact and growth, tackling challenging problems in high-impact mobile features with vast scope for innovation.
What Will You Be Working On?
In this role, you’ll own the iOS experience across both teams, ensuring Wise’s high-volume features are effortlessly accessible on mobile.
- Customers should have smooth experiences when approving transfers (e.g., at the airport), sending hundreds of payments, or buying international property.
- "Seamless mobile integration" is the standard—just as it is on desktop.
