Senior Low level database experience, C++ | Full-time |

About the Project

We are looking for a Senior Database Systems Engineer with deep expertise in low-level database architecture and internals.

This is not a typical backend development role. We are seeking an engineer who understands how databases work under the hood and has hands-on experience with core database components such as transaction processing, storage engines, query planning, indexing, and performance optimization.

• Experience working with low-level database components, including:
  • Transaction Management (ACID, concurrency control, MVCC)
  • Storage Layer / Storage Engines
  • Query Planning and Query Optimization
  • Query Execution
  • Indexing Structures (B-Tree, LSM Tree, etc.)
  • Memory Management
  • Performance Optimization
• Strong debugging and troubleshooting skills
• Experience analyzing and improving database performance
• Understanding of distributed systems principles

Nice to Have

• Experience with:
  • PostgreSQL
  • MySQL
  • ClickHouse
  • RocksDB
  • LevelDB
  • DuckDB
  • ScyllaDB
  • CockroachDB
  • TiDB
• Database kernel development experience
• Experience building or modifying query execution engines
• Familiarity with database compilers and execution frameworks
• Contributions to open-source database projects

Responsibilities

• Design and develop low-level database components
• Improve storage and transaction processing mechanisms
• Optimize query planning and execution performance
• Work on indexing, concurrency control, and data access layers
• Investigate and resolve performance bottlenecks
• Contribute to architecture decisions for high-performance data systems
