Staff Software Engineer, Replicated Storage Services (Replication)

Join MongoDB to build infrastructure that supports fault tolerance, high availability, and tunable consistency. Distributed systems are a core focus of Mongo

DB, so the projects delivered by the Replication Team are highly visible and are typically among the flagship features for each major Mongo

DB release, including multi‑document transactions.

We’re currently working on improving our API and interface boundaries so that we can meet the performance and correctness needs of the world’s most demanding enterprises while enabling new, more efficient data storage and retrieval patterns.

• Strong systems fundamentals, including multi‑threaded programming and performance profiling.
• Familiarity with distributed systems such as consensus protocols, data replication, distributed transactions, and fault tolerance.
• Familiarity with database internals or building core components for data processing systems.
• Excellent verbal and written technical communication skills and a desire to collaborate with colleagues and mentor junior engineers and interns.
• Excellent time management skills and the ability to make realistic assessments of project complexity.
• Passion for learning new things in the domains of computer science and software engineering.

• Develop novel data replication solutions based on the Raft consensus protocol for ensuring automatic failover and zero‑downtime of user applications.
• Handle distributed systems related customer escalations from the Technical Support team.
• Write production‑ready database code in C++.
• Write unit tests and integration tests in C++, JavaScript, and Python to demonstrate application correctness.
• Diagnose test failures, identify bugs in existing code, and fix them.
• Investigate the performance impact of code changes that may cause software performance regressions.
• Interview candidates for software engineering positions.
• Develop and maintain expertise on cutting edge database and distributed systems research from industry and academia.
• Lead development and project management of large, cross‑team projects.
• Collaborate with stakeholders and engineering teams across the company to jointly work on large initiatives.
• Advise Product Management on engineering complexity and inter‑project dependencies.
• Collaborate with Product Management and Engineering leadership to define product roadmaps.

• In the first month, you will have understood the high level architecture of Mongo
  
  DB replication and fixed a few bugs.
• In three months, you will have contributed to the development in C++ of a project slated for the next major release of Mongo
  
  DB, and diagnosed and fixed a few customer or testing‑reported issues.
• In six months, you will have taken on code review responsibilities and are involved in reviewing the design for new features.
