• Analyze and optimize performance, scalability, and resource utilization across the database engine.
• Collaborate with engineering peers to design, review, and evolve core system architectures.
• Contribute to production-grade, maintainable, and well-tested code in a complex, high-scale system.

Qualifications

• Strong proficiency in C++ with experience building performance-critical systems software.
• Demonstrated expertise in multi-threaded programming and concurrency.
• Solid foundation in computer science fundamentals, including data structures, algorithms, and systems design.
• Extensive experience developing software in Linux / Unix environments.
