About the role
Dremio’s Query Execution team builds the runtime responsible for executing analytical queries at scale. The team sits between query planning and table scans, building the systems that turn query plans into efficient, reliable execution.
As a Software Engineer, you’ll work with experienced engineers to build, test, and support well-scoped improvements to the execution engine. You’ll learn how Dremio’s query runtime works while contributing to areas such as query operators, expression evaluation, memory management, scheduling, and performance.
What you’ll be doing
- Build and support execution-engine components: Implement, test, debug, and maintain well-defined changes to query operators, expression evaluation, execution scheduling, and resource management.
- Develop reliable software: Write clear, maintainable Java code; add unit and integration tests; and follow established engineering practices for code review, testing, and documentation.
- Investigate issues: Help diagnose query correctness, reliability, and performance issues using query profiles, logs, telemetry, benchmarks, and production data.
- Learn runtime and performance fundamentals: Build familiarity with vectorized processing, concurrency, memory usage, parallelism, data exchange, and disk spilling.
- Collaborate with the team:...
