MongoDB’s Replication Team builds the infrastructure that enables high availability, fault tolerance, automatic failover, and tunable consistency. As an engineer on the team, you will design and implement distributed-systems features that protect data and keep applications available under demanding operating conditions. You will work primarily in C++ on core database code, partner with engineers across MongoDB, and help shape features that are central to major MongoDB releases. This is an opportunity to apply distributed-systems fundamentals to a widely used database while solving challenging problems in correctness, performance, and operability. We're looking to speak with candidates based in New York City for our in-office working model. What you will do • Design and implement replication features based on the Raft consensus protocol • Improve failover behavior, availability, correctness, and performance across the replication system • Write production-quality C++ and the unit, integration, and system tests needed to demonstrate correctness • Use JavaScript and Python where appropriate to extend test coverage and validate end-to-end behavior • Diagnose test failures, investigate bugs, and drive issues through root-cause analysis and resolution • Measure the performance impact of code changes and prevent or resolve regressions • Collaborate with partner engineering teams and stakeholders on large, cross-functional initiatives • Investigate distributed-systems issues raised by customers and Technical Support, communicate findings clearly, and help deliver durable fixes • Participate in code reviews, design reviews, and technical discussions that improve the quality of the team’s work • Interview candidates and mentor junior engineers and interns What you bring Required • At least five years of experience programming, debugging, and performance-tuning distributed or highly concurrent software systems • Strong systems fundamentals, including multithreaded programming, concurrency, debugging, and performance profiling • Practical experience with one or more distributed-systems concepts, such as consensus protocols, replication, distributed transactions, or fault tolerance • Experience working with complex production codebases and diagnosing problems that cross subsystem boundaries • Strong written and verbal technical communication skills • A collaborative approach and the ability to make realistic assessments of project complexity and delivery risk Preferred • Professional experience developing production software in C++ • Familiarity with database internals or core components of data-processing systems • Experience with Raft or another consensus protocol • Experience writing unit, integration, and end-to-end tests in C++, JavaScript, or Python • Experience responding to customer-impacting production issues in distributed systems • Experience mentoring engineers or interns and contributing to technical hiring Candidates with additional relevant experience may be considered for more senior roles. What success looks like In your first month • Build a working understanding of MongoDB’s replication architecture, development workflow, and testing strategy • Begin resolving scoped bugs and contributing effectively to code reviews In your first three months • Contribute production C++ code to a project targeted for an upcoming MongoDB release • Diagnose and resolve issues identified by testing, customers, or partner teams In your first six months • Take regular ownership of code reviews and participate meaningfully in feature design reviews • Independently drive scoped technical work from investigatio
