Senior Software Engineer (Cluster Scalability)

Join Cluster Scalability, one of MongoDB’s Online Transaction Processing teams, and help build the core infrastructure that makes MongoDB a world-class distributed database

The team builds the infrastructure and tools that let customers scale their workloads past what a single node can handle

We take pride in building clean abstractions over hard distributed systems problems, so users can focus on their data instead of worrying about where it lives or how it’s accessed

Our work has a big impact: it solves the hardest data challenges faced by MongoDB’s largest customers

As a Senior Software Engineer on Cluster Scalability, you’ll work on data partitioning, one of the hardest and most impactful problem areas at MongoDB today

You’ll collaboratively design and build the distributed machinery that turns independent query-processing and storage nodes into a single, unified database system

Your team’s work will be to build the data-movement and dynamic-scaling features that run on top of it

Current work includes seamless horizontal scaling with minimal tradeoffs, better cluster elasticity and smarter workload execution

You’ll solve complex performance problems and design protocols for moving and placing data without disruption

Your work will help the architecture scale reliably to meet customer demand at any volume

Our team champions a strong culture of inclusivity, diversity, and collaboration

If you want to work on a collaborative team that applies distributed systems fundamentals to deliver core features of a popular database, join us!

Let’s change what’s possible for application developers, system architects, and database operators

Success Measures:

In your first month, you’ll understand the high-level architecture of MongoDB, dive into the details of your team’s components, and resolve a few bugs

In the first three months, you’ll contribute to the development of a project slated for the next release of MongoDB, take on code review responsibilities, and participate in design reviews for new features

In the first six months, you’ll lead the development of a new feature and help mentor new engineers on the team- Degree in Computer Science or similar field, or equivalent practical experience, with strong competencies in data structures, algorithms, and software design/architecture
