About the Team The Global Traffic Infrastructure (GTI) team leverages unified platform capabilities to manage edge infrastructure outside China (both self-built and third-party) providing standardized, compliant, scalable, and cost-effective traffic infrastructure capabilities for edge services. Our vision is to build a global edge traffic infrastructure platform and become the long-term cornerstone of ByteDance’s global edge business in terms of scale, performance, and cost.
Responsibilities
- Own the technical architecture and long-term roadmap for GTI's global network and edge traffic infrastructure, supporting large-scale, latency-sensitive services.
- Design and evolve the cloud-native networking stack, including Kubernetes-based Ingress/Gateway and traffic management systems, to improve global traffic scheduling, gateway performance, and resilience.
- Build platform-level abstractions for traffic infrastructure, exposing standardized APIs and reusable capabilities that enable fast integration and innovation for traffic-intensive business teams.
- Drive architectural decisions around global load balancing, cross-region traffic steering, and edge–core collaboration.
- Partner closely with SRE, infrastructure, and product teams to ensure architectures are operable, scalable, and cost-efficient in production.
Requirements
Minimum Qualifications
- Cloud-Native Networking: Strong hands-on experience with Kubernetes networking, Ingress/Gateway (or Gateway API), and designing cloud-native networking platforms.
- Edge Networking & CDN Architecture: Solid understanding of CDN, live streaming, or RTC architectures; experience with global load balancing, Anycast, edge node placement, and cross-region traffic optimization.
- Large-Scale System Design: Proven ability to design and evolve distributed systems operating at global scale with high performance and availability.
- Cost & Capacity Awareness: Experience balancing performance, reliability, and cost in bandwidth, PoP operations, and backbone networking. Preferred Qualifications
- Experience building platformized traffic infrastructure products or APIs used by multiple upstream business teams.
- Strong communication skills with experience collaborating across regions and time zones on complex technical initiatives.
