Role
Who you are
- 10+ years experience in software engineering, with a focus on backend and distributed storage systems
- Expertise in large-scale storage systems, such as distributed databases, cloud object storage (S3, Azure Blob, GCS), or data lake technologies (Iceberg, Delta Lake, Hudi, etc.)
- Strong background in designing and optimizing storage layers, indexing, and data lifecycle management
- Experience optimizing query engines for high-volume, low-latency federated data access
- Track record of improving system reliability, observability, and cost-efficiency
- Experience with Kubernetes-based deployment of distributed storage or query systems
- Proficiency in Go or Java (preferred, but not required)
- Deep understanding of query optimizers, storage formats (Parquet, ORC), and indexing strategies
- Experience with disaggregated storage and cloud-native data lake solutions
- Proven ability to lead technical initiatives as an individual contributor while mentoring senior engineers and driving technical excellence within a team
What the job involves
- MongoDB Atlas Data Federation enables customers to query, transform, and analyze data across multiple sources (MongoDB clusters, cloud object storage, and external databases) through a unified MongoDB query interface—without moving or copying the underlying data. Our system processes hundreds of millions of queries per month and handles exabytes of customer data at scale
- MongoDB Atlas Online Archive provides low-cost, tiered storage for managing infrequently-accessed, read-only data. By optimizing storage layouts during ingestion and rebalancing data dynamically, Online Archive ensures efficient query performance and scalability while managing petabytes of customer data in a rapidly growing system
- As a Staff Engineer on the Atlas Data Federation and Archiving team, you will lead the design, optimization, and scalability of our storage and federated query systems. This role focuses on high-performance distributed storage, data lifecycle management, and efficient data retrieval at scale
- You will work on storage optimization, query execution, and cost-effective data retention strategies—ensuring reliability, performance, and efficiency for thousands of MongoDB Atlas customers who depend on our solutions for critical business operations
- This is a high-impact role for engineers passionate about large-scale data storage, distributed query processing, and system resilience
- Architect and optimize large-scale storage solutions for federated data access, ensuring efficient retrieval, indexing, and query performance
- Optimize data archival pipelines for high-throughput ingestion, durability, and cost-efficiency
- Improve data tiering and lifecycle policies for moving and querying data efficiently across hot, warm, and cold storage tiers
- Reduce operational costs through intelligent storage layout, compaction strategies, and query execution optimizations
- Improve and scale our distributed query execution engine, optimizing it for multi-source federated queries and data lake processing
- Enhance query performance across object storage (e.g., S3, GCS, Azure Blob) by optimizing indexing, partitioning, and compaction techniques
- Implement workload-aware autoscaling for query execution and data processing
- Reduce incident rates by improving system resilience, failover mechanisms, and observability
- Guide architectural decisions and lead design reviews across engineering teams
- Mentor engineers in distributed systems, data storage optimization, and operational excellence
- Partner with Product Management to define the technical roadmap for storage and data federation solutions
- Participate in on-call rotation, providing senior oversight for incident response and postmortem retrospectives
Our take
MongoDB is an open-source, cross-platform, document-oriented database system. It stores data as JSON-like documents and is written in C++, Go, JavaScript and Python.
Essentially, the company develops tools and blueprints to help businesses and organisations modernise their legacy applications, migrating them to the MongoDB database and the MongoDB Atlas cloud database. With this initiative, MongoDB is particularly taking aim at Oracle customers with ageing applications running on the Oracle relational database system.
Since its release, MongoDB has become one of the most popularly used NoSQL database systems due to its ease of use and efficiency. It is also the fastest-growing database ecosystem, and boasts hundreds of millions of downloads. Recently, the company announced a partnership with Patronus AI, an automated evaluation and security platform, through which it will bring automated LLM evaluation and testing capabilities to enterprise customers.
