Senior Software Engineer

Summary

Join MongoDB's Workload Scheduling team as an experienced engineer to build and optimize the operational resiliency of MongoDB clusters. You will be instrumental in developing core server workload management infrastructure, improving performance and stability under load, and moving workload management policies into a separate process for better modularity. This role offers the opportunity to work on a new team, build from the ground up, and make a significant impact. The position can be remote in the US or Canada. Success will be measured by contributions to major releases, bug fixes, code reviews, and leading new feature development.

Requirements

• Minimum 5 years of experience in programming, debugging, and performance tuning distributed and/or highly concurrent low-level software systems
• Strong systems fundamentals, including multi-threaded programming and performance profiling
• Excellent verbal and written technical communication skills and a desire to collaborate with colleagues and mentor junior engineers and interns
• Passion for learning new things in the domains of software engineering, distributed systems, and performance
• Familiarity with distributed system concepts such as fault tolerance, consistency, and availability
• Experience with writing software to observe and mitigate overload scenarios for highly performant and concurrent systems

Responsibilities

• Write production-ready database code in C++, Rust, or possibly another low-level language
• Write unit tests and integration tests in C++, Rust, Javascript, and Python to demonstrate application correctness
• Investigate the performance characteristics of the server and write performance regression tests
• Build and optimize workload management primitives such as operation queueing/ticketing mechanisms as well as load-shedding
• Implement and continuously improve server workload policies to schedule, prioritize, and make decisions about incoming and in-progress operations to maximize goodput while under system load
• Build a process external to the core server that monitors and tunes policies of a MongoDB server
• Improve the workload and system observability/diagnostics of the core server
• Diagnose performance and correctness test failures, identify bugs and/or deficiencies in existing code, and fix them
• Interview candidates for software engineering positions
• Handle customer escalations
• Collaborate with stakeholders and engineering teams across the company to jointly work on large initiatives
• Mentor new and junior engineers on the team, participating in helping facilitate technical growth in the team
• Lead projects through writing scope and technical design documents, and be able to appropriately estimate and plan out execution streams across contributors
