Our diverse portfolio includes relational databases, distributed caches, key-value stores, document databases, graph databases, wide-column stores, search engines, and multi-model databases.\nAbout the Role\nWe are building the next-generation AI-native database systems-intelligent, multimodal, and designed for the era of large models. Our systems are not just data stores; they’re reasoning engines, retrieval platforms, and real-time memory for AI agents. As a Software Engineer or Researcher, you will be at the forefront of rethinking how databases work when built from the ground up for AI workloads. You’ll help create infrastructure that powers intelligent systems across TikTok, CapCut, and future applications that haven’t been imagined yet.\nWe are looking for talented individuals to join us for an internship. PhD internships at Our Company provide students with the opportunity to actively contribute to our products and research, as well as to the organization's future plans and emerging technologies.\nOur dynamic internship experience blends hands-on learning, enriching community-building and professional development events, and collaboration with industry experts.\nApplications will be reviewed on a rolling basis, so we encourage you to apply early. Please clearly state your availability in your resume (Start date, End date).\nResponsibilities\n- Develop kernel modules or features for AI-native database systems.\n- Solve unique, large-scale, highly complex cloud infrastructure problems\n- Partner with PMs and engineers from different teams on building backend support for AI-native database service products\n- Participate in technical discussions related to team's product and engineering work\n任职要求 / Requirements\nMinimum Qualifications\n- Currently pursuing a PhD degree in Computer Science, Computer Engineering, or other related fields\n- Knowledge of database kernel, distributed system, query processing and optimization, multi-threaded programming\n- Experience coding in C/C++, Golang, Java, Python\nPreferred Qualifications\n- Demonstrated software engineering experience from previous internship, work experience, coding competitions, or publications.\n- Curiosity towards new technologies and entrepreneurship.\n- High levels of creativity and quick problem-solving capabilities.\n- Experience with open-source systems such as Faiss, Milvus, DuckDB, ClickHouse, TiKV, RocksDB.\n- Publications at top-tier conferences (e.g., SIGMOD, VLDB, NeurIPS, MLSys, ICDE).\n- Familiarity with GCP, AWS, or Azure’s database and AI integration strategies.\n- Prior contributions to RAG, memory-augmented models, or self-tuning database components.","description_format":"text","description_chars":2832,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":["Professional
