Team Introduction Our Content Delivery Network (CDN) team operates a hybrid platform that combines commercial CDN vendors with ByteDance’s proprietary edge network. This platform spans a large global footprint of Points of Presence (POPs) and supports edge services such as traffic acceleration, CDN caching, gaming, and more. We are looking for experienced reliability and performance engineers to help ensure the stability, reliability, and performance of our edge services and products running on this hybrid CDN platform. This role also involves driving performance optimization and developing innovative solutions to meet evolving business demands at the edge. Site Reliability Engineering (SRE) combines software and systems engineering to build and operate large-scale, highly distributed infrastructure. Our SREs are responsible for ensuring that these infrastructure services are reliable, fault-tolerant, scalable, and cost-efficient. In this role, you will manage complex systems at scale, including hyperscale data centers, public cloud infrastructure, global CDNs, and load balancers that process terabits of traffic per second. You will work closely with cross-functional teams to translate business requirements into actionable plans and drive improvements in system design and operational processes. We are looking for talented individuals to join us for an internship. Our internship program offers students hands-on experience, industry exposure, and opportunities to apply their knowledge to real-world challenges while building a strong foundation for personal and professional growth. Interns will gain practical experience, explore potential career paths, and participate in social events, learning programs, and development workshops alongside industry professionals. Candidates may apply to a maximum of two positions across Our Company and its affiliates globally. Applications will be considered in the order they are submitted. Applications are reviewed on a rolling basis, so we encourage you to apply early. Please clearly state your availability in your resume, including your start and end dates.
