Senior Software Engineer - Global Traffic Infrastructure

About the Team The Global Traffic Infrastructure (GTI) team leverages unified platform capabilities to manage global edge infrastructure (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 - Design, build and operate infra components for global edge PoPs (e.g., Kubernetes/control plane, Virtualization/Container, Ingress/Gateway), with a focus on performance, reliability and security. - Drive end-to-end delivery of cloud-native features from requirements, architecture, implementation and testing to production rollout, troubleshooting and continuous optimization. - Build observability and troubleshooting capabilities for cloud-native based components (metrics/logs/tracing/profiling), and improve incident response efficiency through automation. - Collaborate with SRE, platform, and product teams to provide standardized features and reusable platform capabilities for traffic-intensive services. Minimum Qualification(s): - BS/MS in Computer Science, Computer Engineering or equivalent practical experience. - Strong software engineering fundamentals and solid backend/system development experience in one or more languages such as Go/C/C++/Rust. - Hands-on production experience with containers and Kubernetes (cluster operations, networking, service discovery, Ingress/Gateway, rollout strategies). - Solid understanding and practical experience with cloud-native stack, container/virtualization and network. - Strong problem-solving skills, ownership, and ability to work effectively in cross-functional, fast-paced environments. Preferred Qualification(s): - Experience with or contributions to cloud-native open-source projects (e.g., Kubernetes, Containerd, Cilium/eBPF). - Strong Linux knowledge (kernel, scheduling ,TCP/IP, routing, iptables/nftables) and production troubleshooting experience. - Experience designing multi-tenant isolation, network security controls, and reliability mechanisms for high-traffic systems. - Familiar with CDN, Livestream, RTC or other edge traffic production architecture.
