Director of Engineering, Query Optimization at MongoDB

This role is designed for a seasoned engineering leader with a deep technical background in database internals—specifically query planning, optimization, and execution. You should have at least 10 years of systems programming experience (ideally with C/C++) and 5+ years in management, specifically leading other managers. This is a high-level leadership position that requires the ability to navigate complex distributed systems architecture while driving strategy for a global, multi-model engine. The role offers significant flexibility, allowing for remote work within the Republic of Ireland or a hybrid setup in the Dublin hub. MongoDB provides a comprehensive relocation package for those moving to Ireland. You will lead a prestigious open-source project and influence the roadmap of a industry-standard database platform used by 75% of the Fortune 100. Success is measured by long-term milestones, including defining a 12-month strategic vision and scaling a diverse, geographically distributed team. **You might be a good fit if you...** * Have managed managers and guided the careers of staff-level engineers in a distributed environment. * Possess expert-level knowledge of cost-based optimization, schema inference, and many-core architectures. * Are comfortable diving deep into C++ codebases to weigh in on critical technical decisions. * Excel at cross-functional collaboration with Product and Program Management to ship large-scale infrastructure projects.
