Distinguished Systems Developer - SQL Engine

As a Distinguished Developer in the SQL Engine group, you'll help build the next-generation query processing stack, optimizing across both traditional analytics and emerging AI-driven workloads. You'll contribute to:

• Query parsing, validation, and transformation
• Logical/physical optimization over multi-model data (row, columnar, stream, document, vector)
• Plan generation and adaptive execution strategies
• Code generation and vectorized execution
• Compiler-accelerated storage access patterns for AI workflows
• Collaborative integration with our multi-model storage engine

You'll design data processing abstractions and execution engines that enable AI-native features like fast vector search, graph traversal, and probabilistic joins-all within a familiar SQL interface. Your Impact

• Architect and implement query optimization and execution components that scale across petabytes
• Design tooling and frameworks that make AI and analytics convergence seamless
• Collaborate with platform and storage teams to leverage multi-model indexing and caching strategies
