You'll be on a team responsible for…

• MongoDB Entity Framework Provider
• MongoDB OData integration
• MongoDB Analyzer
• Contributions to the third-party open source libraries that we depend on

• Investigating bugs and support requests from commercial and open source customers for the libraries we maintain
• Seeking out speaking or writing opportunities to engage with our developer community
• Mentoring junior engineers in both technical and non-technical professional skills

Success in this role means…

• Within one month, you will understand the high-level architecture of the driver and how MongoDB works, and will have completed a few small bug fixes and/or feature tickets
• Within three months, you will contribute effectively day-to-day, fix bugs, implement planned features, and thoroughly review your colleagues' pull requests
• Within six months, you will contribute to the roadmap for our products and lead the design and specification of new features. You will have the trust of the team and our internal customers
• Within a year, you will have significantly improved the quality, performance and maintainability of our codebase, and will be taking the lead in designing and specifying major new features
