Що робити

Architect, design, and implement query engine components — planner, optimizer, execution operators, memory management, and data access layers
Diagnose and resolve complex production and customer-reported issues across the full query path — correctness, performance, memory, concurrency, resiliency, and compatibility
Develop, review, and backport fixes across multiple supported release lines; strengthen regression prevention
Write and review high-quality, performance-critical code in Java and/or C++
Analyze query profiles, execution plans, logs, and telemetry to drive performance optimization — profiling, benchmarking, and eliminating bottlenecks in latency- and throughput-sensitive paths
