What You’ll Do

• Develop and scale new query capabilities that directly impact our time-series, Atlas Search, and Vector Search products while adding workload telemetry for greater database insights.
• Contribute high-quality, maintainable code primarily in C++ and gain a deep, working understanding of the MongoDB query engine.
• Work constructively with peers to design, implement, and support robust technical solutions while giving and receiving meaningful feedback in code reviews.
• Build comprehensive testing suites in Python/JavaScript and implement diagnostics to help identify and resolve complex query performance problems.

What We Look For

• 3+ years of experience in computer programming
• Experience in databases and/or data management systems is a huge plus, but not a requirement
• Solid computer science fundamentals, with strong competencies in data structures, algorithms, and software design/architecture
• Experience with large code bases, preferably in C++
• B.Sc. in Computer Science or similar field, or equivalent practical experience
• Interest in the theory and practice of database query engines. Hands-on experience or M.Sc./Ph.D in the domain is a plus
