About Airwallex

Airwallex is the AI-native financial operating system for a real-time, intelligent economy. More than 675,000 businesses, including McLaren Racing, Qantas, SHEIN, and TikTok, use us, directly or through our platform partners, to run their financial operations or build and monetize financial products of their own.

We started in Melbourne in 2015 to build the infrastructure global commerce runs on. We're the regulated backbone behind global payments: not by accident, but by design. A decade plus, 85+ licenses, and a financial infrastructure spanning North America, Europe, the Middle East, and Asia-Pacific.

We're co-headquartered in San Francisco and Singapore, with more than 2,300 people across 27 offices. We hire builders with founder-level energy, people who move fast with good judgment, dig in with real curiosity, and make calls from first principles rather than waiting to be told what to do. Read our operating principles to see it in full.

How you'll make impact

You'll help build the platforms and integrations that connect Airwallex with the software our customers already rely on. You'll work across ecosystem products, developer infrastructure and partner integrations to make financial operations simpler and more connected.

Design and evolve platforms and integrations across accounting, HR, ERP, marketplace, payment and open-banking systems.

Build secure, reliable APIs, SDKs, webhooks and UI-extension patterns that enable third-party developers and partners to build on Airwallex.

Shape the technical roadmap for the App Marketplace and Extension Framework, contributing to architectural decisions, coding standards, observability patterns and security practices.

Improve the developer experience through clear documentation, sandboxes and tooling, while partnering with backend, product, design and go-to-market teams.

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

What we're looking for

Essentials

A bachelor's degree in Computer Science, Software Engineering or a related field.

2+ years of experience developing internet applications, large financial systems or e-commerce platforms.

Strong programming or scripting skills in a language such as Java, Kotlin, C++, Python or a similar language.

Direct experience building or maintaining a public-facing developer platform, app marketplace or extension framework.

Experience designing and building APIs and integrations with external financial institutions or third-party platforms.

Experience developing scalable, reliable systems and working effectively with cross-functional teams.

Preferred

Deep expertise in Domain-Driven Design and applying it to complex business logic and microservice boundaries.

Hands-on experience with cloud-native technologies such as Docker, Kubernetes and advanced observability tools.

Experience integrating AI or large language models to automate integration workflows or improve developer tooling.

You'll thrive here if

You're comfortable owning the roadmap yourself.

You own the outcome and you don't wait for permission to fix what's broken.

You're comfortable with ambiguity. Give you a problem, not a prescription, and you'll run with it.

You say what you mean. You're direct, but you lead with respect.

You simplify complexity rather than hiding behind it.

You'll work closely with backend, product, design, and go-to-market teams to ship secure, reliable experiences. If you want to simplify financial operations for businesses of all sizes and unlock new use cases on top of the Airwallex business account, this is where that work happens.
