Senior Mobile Engineer (iOS), Global Payments

How you'll make impact

You’ll build Airwallex’s mobile payment solutions for customers acquiring payments from shoppers across the globe. You’ll lead the development of the Airi Consumer Wallet, Airwallex’s first consumer-facing wallet application and a networked checkout solution that builds a persistent shopper profile across its global merchant network.

• Build secure, reliable, maintainable and developer-friendly iOS applications and libraries using native technologies.
• Partner with engineering, product and internal business teams to define requirements, develop technical specifications and deliver products end to end.
• Improve payment security and customer trust across real-time transaction scenarios, sensitive customer data and global regulatory requirements.
• Refactor code and designs with architects to improve maintainability, extensibility and reusability.
• Contribute to the broader engineering community as Airwallex grows and the roadmap evolves.

You’ll work from our Singapore office five days a week.

What we're looking for

Essentials

• A BS or MS degree in Computer Science or an equivalent discipline.
• 5+ years of professional experience developing native iOS applications with Swift or SwiftUI.
• Expert knowledge of iOS frameworks and the broader iOS ecosystem.
• A strong understanding of design patterns for mobile development.
• Experience working with RESTful APIs.
• A track record of writing robust, maintainable code with high test coverage.
• Experience maintaining automation pipelines for CI/CD.
• The ability to work independently and collaboratively.
• Fluency in English.

Preferred

• Experience developing for Android or familiarity with the Android platform.
• Exposure to cross-platform frameworks such as React Native.
• Experience working with Objective-C.

You'll thrive here if

• You're comfortable owning the roadmap yourself.
• You're comfortable making decisions with incomplete information and moving quickly anyway.
• You hold yourself to a high standard even when no one is watching. Quality and accountability aren't external expectations, they're internal ones.
• You're comfortable operating across time zones with a globally distributed team, including colleagues based in APAC and EMEA.
• You say what you mean. You're direct, but you lead with respect.

Learn more about your team

Engineering at Airwallex is for people who want to define a category, not maintain one. We're reimagining how businesses interact with finance from the ground up, AI- and agent-native by default, think agent wallets, agentic bookkeepers, and spend-management autopilots, with APIs designed for agents as first-class users. The hard part is trust: building agent-native systems precise enough to move real money autonomously, on top of a decade of real infrastructure.

This is a team for engineers who'd rather own an unsolved problem than inherit a mature one. If you want frontier problems, teammates who raise your standards, and a genuine clean slate on world-class infrastructure, this is the place to build it.
