About the Role
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 experts 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 (think 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, all embedded directly into our edge stack.
-
Self‑Service Tooling: Create CLI/plugins and lightweight frameworks so other teams register APIs, enforce policies, and preview traffic insights in seconds.
-
Rock‑Solid Reliability: Dive into metrics, pinpoint latency or fail‑over gaps, and deliver code‑level optimizations to keep every request fast and flawless.
Minimum Qualifications
-
Bachelor’s degree or above 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.
