ByteDance is looking to build and own cutting-edge database products supporting its global infrastructure, specifically AI-native database systems for large models
Requirements
- Strong coding and system-level design skills in C++ / Rust / Go
- Deep expertise in one or more of the following areas: Storage engine architecture (LSM-trees, column stores, HTAP systems) / Vector retrieval systems, similarity search, and ANN indexing / AI infra or model-serving infrastructure (especially for embeddings / RAG / LLMs) / Semantic search, agent systems, or AI-native memory frameworks
- Experience with open-source systems such as Faiss, Milvus, DuckDB, ClickHouse, TiKV, RocksDB
- Familiarity with GCP, AWS, or Azure’s database and AI integration strategies
- Prior contributions to RAG, memory-augmented models, or self-tuning database components
- Publications at top-tier conferences (e.g., SIGMOD, VLDB, NeurIPS, MLSys, ICDE)
- 2+ years in core database systems, large-scale distributed infrastructure, or machine learning systems
Responsibilities
- Architect and implement AI-native databases that seamlessly integrate structured, unstructured, and vectorized data.
- Design storage engines optimized for embedding ingestion, multimodal retrieval, and real-time AI interaction.
- Build scalable and distributed vector search systems with low-latency guarantees.
- Develop AI-augmented query processors that leverage large language models (LLMs) for semantic parsing, intent understanding, and cost estimation.
- Collaborate on developing retrieval-augmented generation (RAG) infrastructure and LLM agent memory backends.
- Drive innovations in learned index structures, self-optimizing databases, and AI-integrated transaction systems.
- Publish and contribute to broader research and open-source communities.
