Software Engineer Intern (Traffic Infrastructure) - 2027 Summer

ByteDance is a technology company whose mission is to inspire creativity and enrich life through a suite of global content and social products. The Software Engineer Intern will work with the Traffic Infrastructure team on production systems supporting global edge traffic, contributing to infrastructure design, cloud-native feature delivery, observability, troubleshooting, and automation.

What you'll do:

• 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

What they're looking for:

• - Currently pursuing an 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
• - 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

Benefits:

• Interns have day one access to health insurance, life insurance, wellbeing benefits and more.
• Interns also receive 10 paid holidays per year and paid sick time (56 hours if hired in first half of year, 40 if hired in second half of year).
• Interns who are not working 100% remote may also be eligible for housing allowance.
• Mentorship throughout the internship.
• Hands-on experience and industry exposure.
• Opportunities to apply knowledge to real-world challenges while building a strong foundation for personal and professional growth.
• Participation in social events, learning programs, and development workshops.
