MongoDB’s mission is to empower innovators to create, transform, and disrupt industries by unleashing the power of software and data. We enable organizations of all sizes to easily build, scale, and run modern applications by helping them modernize legacy workloads, embrace innovation, and unleash AI. Our industry-leading developer data platform, MongoDB Atlas, is the only globally distributed, multi-cloud database and is available in more than 115 regions across AWS, Google Cloud, and Microsoft Azure. Atlas allows customers to build anywhere—on the edge, on premises, or across cloud providers. With offices worldwide and over 175,000 developers joining MongoDB every month, it’s no wonder that leading organizations, like Samsung and Toyota, trust MongoDB to build next-generation, AI-powered applications.

About The Team

Atlas Data Federation gives developers a powerful way to query, transform, and analyze data combined across a variety of sources—including multiple MongoDB Atlas clusters and cloud object storage (like Amazon S3)—without needing to copy or move the data. By extending the MongoDB Query Language (MQL) to remote sources, we offer a seamless way to work with distributed data through a single interface.

Our team builds and operates the backend systems that make this possible—from query planning and optimization, to execution and data access across heterogeneous backends. We own critical infrastructure that operates at high volume and low latency, handling complex federated queries over exabytes of data.

What You’ll Do

As a senior software engineer on the Atlas Data Federation (ADF) team, you’ll be trusted with high-impact, high-visibility work on a rapidly growing platform. You’ll have the opportunity to design and implement core components of our distributed query engine. Your work will directly improve the performance, memory efficiency, and reliability of our systems. In addition, you’ll play a key role in improving our distributed control plane, which manages infrastructure and workload routing across the system. You'll participate in on-call rotations, leading incident response and postmortem analysis. Collaboration is central to this role—you’ll partner closely with other MongoDB teams, including those working on drivers, the core server, and cloud services, to ensure seamless integration and a cohesive developer experience.

What We Look For

3+ years of experience working on database or storage internals, or building core components of data processing systems such as query execution engines, storage layers, workload optimization, or autonomous tuning
Proficiency in systems programming with languages like Go, Java, C++, or Rust
Hands-on experience building and operating distributed systems at scale
Excellent verbal and written technical communication skills and desire to collaborate with colleagues, mentor fellow engineers and lead projects
Bachelor’s or Master’s degree in Computer Science or a related field, or equivalent practical experience

Success Measures

In 3 months, you’ll have contributed to a key project and fixed a few impactful bugs
In 6 months, you’ll be reviewing code and involved in design discussions for new features
In 12 months, you’ll lead a major initiative and mentor newer engineers on the team
