Software Engineer Intern (Traffic Infrastructure) - 2027 Summer

About Us

Founded in 2012, ByteDance's mission is to inspire creativity and enrich life. With a suite of products including TikTok, Lemon8, CapCut, and Pico, as well as platforms specific to the China market like Toutiao, Douyin, and Xigua, ByteDance makes it easier and more fun for people to connect with, consume, and create content.

The Traffic Infrastructure (TI) 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

• Assist in the design, development, and operation of infrastructure components for global edge PoPs (e.g., Kubernetes/control plane, virtualization/containers, Ingress/Gateway), with close guidance from senior engineers, focusing on performance, reliability, and security.
• Participate in the delivery of cloud-native features — from requirements and implementation to testing and rollout — while learning our engineering best practices.
• Help build observability and troubleshooting tooling (metrics/logs/tracing/profiling) and contribute to automation that improves incident response efficiency.

Qualifications

Minimum Qualifications:

• Currently pursuing a Bachelor's degree in Computer Science, Computer Engineering, Software Engineering, or a related technical discipline.
• Solid foundation in software engineering fundamentals (data structures, algorithms, operating systems, computer networks).
• Programming experience in one or more languages such as Go, C, or Rust, demonstrated through coursework, personal projects, or open-source contributions.
• Familiarity with Linux and basic understanding of containers, distributed systems, or networking concepts.
• Strong problem-solving skills, a growth mindset, ownership, and eagerness to learn in a collaborative, fast-paced environment.

Preferred Qualifications:

• Prior internship, co-op, or research experience related to backend/systems development, cloud-native technologies, or infrastructure.
• Hands-on exposure to containers and Kubernetes through coursework, side projects, or internships (e.g., deploying applications, basic cluster operations, service discovery, Ingress/Gateway).
• Contributions to cloud-native open-source projects (e.g., Kubernetes, Containerd, Cilium/eBPF), even at a small scale.
• Deeper Linux knowledge (kernel, scheduling, TCP/IP, routing, iptables/nftables) gained through projects or self-study.
• Coursework, projects, or curiosity around CDN, live streaming, RTC, or other edge/traffic-intensive architectures.

Pay

The hourly rate range for this internship position is $45-$45.
