Senior Software Engineer, Edge Team

About Airwallex

Airwallex is the AI-native financial operating system for a real-time, intelligent economy. More than 676,000 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.

About the Team

Tech Platform exists to provide reusable platform services so product and domain teams can move faster without rebuilding common infrastructure themselves. The clearest documented mission statement comes from Substrate: to provide modular traffic-management solutions for multi- data-center infrastructure, secure service communication, and adaptive request management so domain engineers can stay focused on business value. Taken together, this positions Tech Platform as a leverage team that improves engineering efficiency, standardisation, reliability, and developer experience across the organisation.

About the Role

We are looking for skilled Senior 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.

Responsibilities

• 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.
