A bachelor's degree in Computer Science, Software Engineering, or a related field.
8+ years of professional software engineering experience, including experience in technical leadership roles.
Proven experience architecting and scaling backend systems and APIs in production.
Strong computer science fundamentals, including data structures, algorithms, and distributed systems.
Expertise in at least one backend language, such as Java, Kotlin, Go, or Python.
Deep understanding of REST API design and modern backend frameworks, such as Spring Boot.
Experience with cloud infrastructure, such as AWS or GCP, and container orchestration tools such as Kubernetes.
Strong commitment to code quality, reliability, and performance.

Experience leading cross-team initiatives and influencing technical direction at a system-wide level.

YOU'LL THRIVE HERE IF
You're comfortable owning the roadmap yourself.
You're comfortable with ambiguity. Give you a problem, not a prescription, and you'll run with it.
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 enjoy working closely with people across multiple countries and time zones as part of one connected, global team, including flexing your hours occasionally to make that connection work.
LEARN MORE ABOUT YOUR TEAM
The Spend team builds Airwallex's financial operating layer for modern businesses, bringing together corporate cards, expenses, bills, and procurement on top of our accounts, payments, and issuing infrastructure. We're building AI that makes real decisions about expenses, policies, and payments, aiming to get 95%+ of submissions down to one click, while every workflow still has to hold up across multi-entity businesses, currencies, and audit trails. This is a team for people who want broad ownership across product, data, and AI, while the roadmap is still being defined. If you want to build production AI for real financial workflows that directly change how businesses operate, this is where that work happens.
