About the Role

We’re looking for a seasoned Principal Engineer to take full ownership of Airwallex’s edge networking stack—including API gateway, CDN, DNS, Global Accelerators, and traffic control services. This is a high-impact P5 architect role at the intersection of platform engineering, security, and product velocity. You’ll define the blueprint, lead implementation, and enforce governance for how all external traffic reaches and interacts with our platform globally.

Responsibilities🌐 Own the Edge Network Stack
  • Design and evolve the architecture for Airwallex's external traffic stack including:

    • API Gateways (routing, filtering, throttling)

    • DNS services (global resolution & routing)

    • CDNs (caching strategies and invalidation)

    • Global Accelerators (latency and route optimization)

🔐 Define and Enforce Border Security
  • Partner with InfoSec to design and operationalize:

    • DDoS protection, bot mitigation, and anomaly detection (e.g., Cloud Armor, WAF)

    • Rate limiting and QoS policy enforcement for prioritized customer/partner APIs

    • Firewall rule governance and bad actor prevention mechanisms

    • Intrusion Prevention and Auth mechanisms at the border

📦 Policy-Driven API Route Management
  • Build end-to-end processes and tooling for how engineers expose public APIs:

    • Define policy and controls for route registration, approval, and change management

    • Work with platform teams to enforce compliance across microservices and gateways

    • Contribute to internal tools for observability, access review, and lifecycle auditing

🚦 Enable Global-Scale, Secure Performance
  • Establish reliability and quality of service (QoS) goals for critical paths (e.g., payments, onboarding, auth)

  • Design for hybrid/multi-cloud edge strategy and backbone traffic replication

  • Tune latency, failover, and availability posture across regions

What We’re Looking ForTechnical Skills
  • Deep experience in cloud-native edge networking (API Gateway, DNS, CDN, GA, firewalls)

  • Proficiency with SDN concepts and tools (e.g., OpenDaylight, Envoy, NGINX/OpenResty, Kong, Apisix)

  • Familiar with Cloudflare, AWS or GCP Cloud Networking, techniques

  • Knowledge of hybrid/multi-cloud patterns and traffic engineering at scale

  • Hands-on with cloud firewall systems, WAF, rate limiting, and bot detection

Strategic Capabilities
  • A security-aware mindset with ability to balance protection and developer experience

  • Experience defining cross-team processes and governance frameworks

  • Strong communication skills and ability to lead across engineering and security teams

Bonus
  • Experience supporting financial or regulated workloads

  • Familiarity with Kubernetes traffic management frameworks

  • Mandarin fluency and experience working in global, multi-timezone environments
