Infrastructure

Employment Type:

Regular

Job Code: A89318

We are the Infrastructure System Lab — a hybrid research and engineering group building the next‑generation AI‑native data infrastructure. Our work sits at the intersection of databases, large‑scale systems, and AI. We drive innovation across the following areas:

• Next‑generation databases:
  We build VectorDBs and multi‑modal AI‑native databases designed to support large‑scale retrieval and reasoning workloads.
• AI for Infra:
  We leverage machine learning to build intelligent algorithms for infrastructure optimization, tuning, and observability.
• LLM Copilot:
  We develop LLM‑based tooling like NL2
  
  SQL and NL2
  
  Chart.
• High‑performance cache systems:
  We develop a multi‑engine key‑value store optimized for distributed storage workloads, including KV caches for LLM inference at scale.

• Research cutting‑edge technologies in the field of data management and security.
• Participate in the design and development of innovative data management and security projects, providing technical architecture and implementation plans that consider performance, stability, scalability, and security.
• Submit high‑quality code and complete development tasks on time according to project schedules.
• Publish papers in top academic conferences (e.g., SIGMOD, VLDB, CCS).

• Master's degree or higher in Computer Science or a related field, with a solid foundation in data structures and databases.
• Familiarity with Unix/Linux operating systems and proficiency in mainstream programming languages such as C/C++, Go, and Java.
• In‑depth knowledge of database principles and common solutions and techniques for data security and privacy protection.
• Strong logical reasoning, quick learning of new technologies, excellent problem‑solving skills, and a strong sense of responsibility.
• Published papers in accredited academic conferences (e.g., SIGMOD, VLDB, CCS).

• Research experience in the intersecting areas of security, AI/LLM, and data management.
• Experience in the development of relational databases, No
  
  SQL, or blockchain cores.
• Knowledge of blockchain principles and technologies such as Bitcoin, Ethereum, Libra, Hyperledger Fabric, etc.
• Understanding of blockchain database systems like QLDB, LedgerDB, Oracle Blockchain Table, Microsoft SQL Ledger, etc.
• Proficiency in encryption/decryption algorithms, authentication and signature algorithms, hash algorithms, security protocol design, access control models, and software security theories.
• Research and practical experience in the security field, including Trusted Execution Environment (TEE), secure multi‑party computation, differential privacy, homomorphic encryption, threshold cryptography, function encryption, searchable encryption, zero‑knowledge proofs, and cryptographic applications in blockchain.
• Experience optimizing cryptographic algorithms, implementing cryptographic libraries, or working on large‑scale cryptographic applications.
• Winners of programming competitions.
