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 Byte Dance’s global edge business in terms of scale, performance, and cost.

Responsibilities:

• Design, build and operate infra components for global edge Po Ps (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.

Requirements:

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.
