Senior Software Engineer, Query Optimization

MongoDB is a data platform company that builds distributed database technologies. The Senior Software Engineer will design and build query optimization and execution systems, research query systems, and provide technical direction for database performance, robustness, and language enhancements. The role also includes implementing and supporting features, coordinating changes across teams, and mentoring engineers.

Responsibilities:

• Innovate in the area of flexible schema databases. Help us build a world-class query optimization system
• Research state-of-the art query systems to inform our design
• Leverage deep knowledge of the strength and weakness of the product and of industry trends to provide technical vision and direction
• Set initiative level strategy, architect plans, and lead the team towards successful execution
• Advise and partner with management on roadmap decisions, processes, and architectural designs
• Identify, design, implement, test, and support new features related to query performance and robustness, query language enhancements, diagnostics, and integration with other products and tools
• Work with other engineers to coordinate seamless changes in a feature-rich, large code base
• Work with other teams including client drivers, cloud services, enterprise tools, support, consulting, education, and marketing to coordinate changes or contribute to their projects
• Influence and grow team members through active mentoring, coaching and leading by example

Requirements:

• 5+ years of experience in data management systems, distributed systems, or large-scale backend engineering
• Experience with building production-level code with a large user base, robust design structure and rigorous code quality
• Degree in Computer Science or similar field, or equivalent practical experience, with strong competencies in data structures, algorithms, and software design/architecture
• Experience with large code bases written in C++ or another systems programming language. You'll need to trace down defects, estimate work complexity, and design evolution and integration strategies as we rewrite different components of the system
• A strong foundation in core database internals is essential
• This role can be based remotely in the U.S. or Canada, limited to Eastern or Central time zones only
• While direct experience in query optimization is a massive bonus, it is not a prerequisite
• We are also excited to meet candidates with strong backgrounds in compilers, language transpilers, or distributed storage systems
