About the Team
Our team builds a global copyright protection platform that translates legal requirements, business policies, and operational workflows into reliable and scalable systems. The platform supports complaint intake, regional routing, human review, enforcement, notifications, creator appeals, rightsholder rebuttals, and proactive content identification.

You will work on complex event-driven systems and multi-region distributed architectures, addressing real-world challenges in consistency, idempotency, cross-region routing, reliability, and compliance.

What We Offer
- Direct involvement in the design and development of TikTok's global copyright protection core systems, with business impact reaching hundreds of millions of users worldwide.
- Hands-on experience with Go microservices architecture, event-driven architecture, and multi-data-center distributed systems.
- Comprehensive mentorship program (1:1 Mentor) with a clear growth path - full-cycle participation from requirement analysis to production deployment.
- A collaborative, cross-functional environment working with product, algorithm, and front-end teams, enabling rapid cross-domain learning.
- Competitive compensation and benefits; outstanding interns/new grads will receive full-time conversion opportunities.

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.

- Design, optimize, and maintain databases (MySQL/NoSQL) supporting efficient storage and querying at billion-scale data volumes, ensuring data integrity and consistency.
- Develop and maintain RESTful APIs and RPC interfaces, ensuring efficient and secure data exchange between front-end applications, internal platforms, and external systems.
- Participate in system design and data synchronization strategies for multi-DC (Multi-Data Center / Multi-VGeo) architecture, solving distributed challenges such as cross-region replication lag and read-after-write consistency.
- Monitor and optimize system performance, identify and resolve potential bottlenecks, and improve system throughput and response speed.
