Our Database Experience (DBX) Team

A great MongoDB experience starts with great tools.

The Database Experience team builds the libraries and tools that developers use day-to-day working with MongoDB. Our mission is to increase developer adoption, satisfaction and retention by providing a reliable, enjoyable interface for developers and other end-users.

Our senior engineers are typically specialists in a particular programming language, but are capable of contributing to projects in other languages as well.

For this role, we're looking for someone who will enjoy designing, writing, and supporting open source libraries for the Python ecosystem developers that use MongoDB. This is an opportunity to make a major impact at MongoDB as Python is one of the most popular runtimes for MongoDB users, and our driver has over 3 million daily pypi downloads.

You might be right for this role if you...

Have substantial experience writing high-quality software in Python

Have extensive knowledge in Python tools and frameworks, scientific python and web development frameworks

Have practical experience with AI/ML frameworks and technologies in Python, including large language models and agentic tools are a plus

Have an interest in learning and staying up-to-date with Python ecosystem trends and best practices and incorporating them into your work

Can make pragmatic design decisions, balancing tradeoffs such as usability, maintainability and delivery time

Want to, or already do, participate in open source software development and communities, both online via e.g. GitHub and optionally through conferences and speaking engagements

Communicate well, internally and externally, both verbally and in writing

Enjoy collaborating with teammates, and mentoring junior engineers and interns

Are self-motivated, organized, and have strong time management skills

You'll be on the team responsible for...

Developing and supporting the MongoDB Python drivers and subsidiary libraries (PyMongo, Django MongoDB Backend, PyMongoArrow, LangChain MongoDB) and related software, collaborating with peers in our distributed world-wide engineering team

Writing and maintaining open source specifications defining common behavior and APIs shared across all of our drivers

Investigating bugs and support requests from commercial customers, open source users, and internal users for the libraries our team maintains

Working with our Product and Server teams on designs and specifications for new user-facing MongoDB features

Success in this role means...

Within one month, you will understand the high-level architecture of the drivers and how MongoDB works, and will have completed a few small bug fixes and/or feature tickets

Within three months, you will be contributing effectively day-to-day, fixing bugs, implementing features, investigating and responding to open source user and customer issues, and reviewing your peers' code

Within six months, you'll have implemented major, planned new features, contributed to our common driver specifications, shipped a major feature in an open source library, and will be collaborating with the Product team to help craft our roadmap

Within twelve months, you'll have significantly improved the quality, performance and maintainability of our codebase, and will be taking the lead in designing and specifying major new features
