About the job
The TikTok Datastore Service team designs, builds, and governs the core online storage infrastructure that powers our global products. Our mission is to provide data services with ultimate performance, reliability, and intelligence for hundreds of millions of users and countless business scenarios worldwide. Here, you will tackle world-class challenges in globalization, multi-region active-active architecture, compliance, and cost efficiency, while leveraging AI to drive the evolution of next-generation storage architecture.
Responsibilities
- Architect, develop, and evolve TikTok's global online data store platform (including databases, caches, and data synchronization), focusing on global business scenarios to solve core challenges such as multi-region deployment, active-active architecture, data consistency, compliance, and cost optimization.
- Pioneer the innovation and implementation of AI in the storage domain, building core AI skills for online data storage. You will explore the deep integration of AI with storage systems (e.g., AI-assisted data insights, AI-assisted architecture governance, anomaly detection) and advance the application of AIOps in large-scale storage systems.
- Act as a subject-matter expert on storage, collaborating closely with business teams and architects. Provide professional technical consultation, and design and drive the implementation of global data storage solutions that meet business needs while ensuring high performance, availability, and consistency.
Qualifications
