Singapur, Singapore Airwallex Full time

Staff Software Engineer, Edge Infrastructure

Airwallex is the only unified payments and financial platform for global businesses. Powered by our unique combination of proprietary infrastructure and software, we enable thousands of businesses worldwide with fully integrated solutions to manage payments, spend management, treasury, and embedded finance at a global scale.

Airwallex is founded in Melbourne with a global team and offices around the world. We value builders who want real impact, accelerated learning, and true ownership, and we move fast with good judgment and curiosity.

Overview

We are looking for skilled Staff Software Engineers to help shape and evolve Airwallex’s edge infrastructure. You’ll architect and build the software foundations that power Airwallex’s global edge. You’ll write high‑quality code, design scalable services, and own end‑to‑end features that make our API gateway, CDN layer, DNS routing, and perimeter security smarter, faster, and more resilient. You’ll partner closely with product, platform, and security teams to translate real‑world requirements into clean, maintainable code and see your work go live for millions of requests every day.

What You’ll Be Doing
  • Next‑Gen Edge Services: Architect and ship new gateway and CDN features (plugin‑driven routing, smart cache policies, dynamic purge APIs).
  • Security as Code: Build libraries and pipelines for rate limits, WAF/filter rules and bot detection, embedded into the edge stack.
  • Self‑Service Tooling: Create CLI/plugins and lightweight frameworks for other teams to register APIs, enforce policies, and preview traffic insights quickly.
  • Rock‑Solid Reliability: Analyze metrics, identify latency or failover gaps, and deliver code‑level optimizations to keep every request fast and reliable.
Minimum Qualifications
  • Bachelor’s degree or higher in Computer Science, Engineering, or a related field.
  • 5+ years of back‑end development experience, building large‑scale, high‑throughput services.
  • Proficient in one or more languages such as Java, Go, Python, or similar, with strong software design and system thinking skills.
  • Comfortable partnering across product, platform, and security teams; able to explain complex ideas clearly.
Preferred Qualifications
  • 3+ years designing and operating distributed, low‑latency systems (API gateway, cache, etc.) or security‑focused development.
  • Use data to identify performance or reliability bottlenecks and deliver targeted code‑level improvements.
  • Thrive in a fast‑paced environment, take full ownership of your work, and continuously iterate based on feedback.

Airwallex is proud to be an equal opportunity employer. We value diversity and welcome applicants based on merit, qualifications, competence and talent. We don’t discriminate based on color, religion, race, national origin, sexual orientation, ancestry, citizenship, sex, marital or family status, disability, gender, or any other legally protected status.
