As a Senior Cloud Engineer – Distributed Database & Middleware, you will design and optimize the architecture of distributed database and middleware systems to ensure scalability, high availability, and fault tolerance. You will drive data governance strategies, optimize performance across multiple layers, and implement disaster recovery plans to ensure business continuity. Additionally, you will collaborate with cross‑functional teams and mentor engineers in database management, system stability, and performance tuning.

• Architecture Design
  • Design the overall architecture of distributed database and middleware systems to ensure high availability, scalability, and fault tolerance.
  • Integrate open‑source components to build solutions that meet enterprise‑grade standards.
• Database Underlying Governance & Data Processing
  • Conduct in‑depth research and optimization of database underlying data governance, including data storage formats, data structures, indexing methods, data sharding, data compaction, data compression, data validation and repair, as well as data backup and recovery.
  • Formulate efficient data governance strategies to ensure high‑performance and secure data processing in a distributed environment.
• Performance Tuning & Resource Optimization
  • Optimize multi‑layer resources, including operating system I/O and network performance, to ensure system stability and high performance in complex environments.
  • Monitor system performance metrics to promptly identify and resolve issues.
• System Maintenance & Disaster Recovery Design
  • Design and implement routine operations, data backup and recovery, and disaster recovery plans to ensure business continuity.
  • Establish operational standards for distributed applications and continuously optimize system stability and recoverability.
• Team Collaboration & Technical Guidance
  • Collaborate closely with cross‑functional teams (development, operations, security, etc.) to ensure project success.
  • Mentor team members in distributed systems, database governance, and performance tuning practices to elevate the overall technical expertise within the team.

• Educational Background
