The MongoDB Developer Productivity team provides a highly leveraged foundation of shared tools and services that support our product development process. We succeed when MongoDB product and engineering teams are able to deliver the best solutions to our customers through a highly effective software development process.
The Performance Infrastructure Team aims to make it as easy as possible for MongoDB engineers to test and improve the performance of MongoDB products. As a Software Engineer 2, you will work closely with performance-focused engineers across the organization to design, build, and maintain our world-class performance benchmarking system and supporting tooling.
This role requires a hybrid working model based out of our office in Sydney, Australia.
What we are looking for in you
* A Bachelor's or Master's degree in Computer Science, Computer Engineering, Software Engineering, or a related field.
* A solid foundation in computer science fundamentals (data structures, algorithms, software design) and an ability to apply them to real problems.
* Proficiency in at least one modern programming language; Python is strongly preferred for this role, but experience in languages such as Go, Java, C++, or similar is also valuable.
* Experience writing and testing software via internships, personal projects, open source contributions, coursework, coding competitions, or research. You can point to code you've written that you're proud of, and explain the trade-offs you made.
* An interest in or exposure to modern software delivery practices (e.g., CI/CD, containers, cloud platforms, observability tooling), and curiosity to go deeper. Prior hands-on experience is a plus but not a requirement for success in this role.
* Growing skills in clear written and verbal communication: you can explain what you're working on, ask good questions, and incorporate feedback. You're motivated to keep improving in this area.
* A growth mindset: you seek feedback, learn from mistakes, and look for opportunities to take on slightly more complex work over time.
* We do not expect you to arrive as a performance expert or infrastructure specialist. We are looking for early-career engineers who are excited to learn how large-scale systems are built, measured, and improved, and who want to grow into owning more complex projects over time.
What you'll find at MongoDB
As a Software Engineer 2 on Performance Infrastructure, you will:
* Design, implement, and test features and bug fixes in our performance tooling and infrastructure, primarily using Python, with guidance from more senior engineers where needed.
* Contribute to performance workloads and benchmarking pipelines used to evaluate MongoDB across releases, platforms, and configurations, helping the broader organization understand how changes affect our products.
* Maintain and improve existing performance testing software by refactoring code, improving test coverage, and simplifying developer experiences for MongoDB engineers who use our tools.
* Work with teammates to debug and diagnose performance or reliability issues, learning how to use internal observability tools, logs, traces, and metrics to narrow down root causes.
* Participate actively in code reviews, both as an author and as a reviewer, asking clarifying questions and incorporating feedback to improve code quality and maintainability.
* Help keep our documentation, runbooks, and "getting started" guides for performance tooling accurate and approachable, especially for other early-career engineers and internal users.
* Build strong working relationships with engineers across MongoDB, representing user needs and pain points you encounter in your work and through support requests from other teams.
* Over time, take end-to-end ownership of small-to-medium-scoped projects, including breaking work into incremental pieces, communicating progress, and delivering improvements that meaningfully impact developer productivity and performance testing reliability.
* You will be supported by a manager and teammates who will help you scope your work appropriately for your experience level, while expecting you to become increasingly independent as you grow in the role.
Success measures
We measure success for this role along both impact and growth, consistent with MongoDB's expectations for early-career software engineers.
* In 1 month
o You have a basic understanding of our primary tools, systems, and team workflows, and can set up and run our core performance workloads locally or in CI with guidance.
o You have completed several small, well-scoped tasks (documentation fixes, simple bug fixes, or small quality-of-life improvements) and learned our code review and release processes.
o You are comfortable asking questions, pairing with teammates, and using internal channels to get unblocked.
* In 3 months
o You are independently productive in familiar areas of the codebase, taking well-defined tickets from design to implementation, test, and deployment with limited supervision.
o You have contributed meaningfully to at least one performance-related feature or improvement, such as a new workload, better observability, or test stability work, and can explain its impact on our users (MongoDB engineers) and downstream teams.
o You troubleshoot and resolve moderately complex bugs with help from teammates, and you routinely file clear follow-up tickets when you discover gaps in tests, docs, or tooling.
* In 6 months
o You can own small-to-medium complexity projects in areas you know well, including breaking work into incremental changes, estimating effort with your manager, and keeping stakeholders up to date on progress and risks.
o You show good judgment in balancing quality and velocity, knowing when to ship a pragmatic solution and when to slow down to pay down technical debt or add tests.
o You increasingly contribute to improving our tools and processes, e.g., suggesting changes to make performance runs more reliable, clarifying documentation, or reducing friction in common workflows.
* In 12 months
o You are a trusted contributor on the Performance Infrastructure team: your team and manager are confident relying on you to take on new work in your core areas with minimal day-to-day supervision.
o You have made one or more visible improvements to our performance tooling, workloads, or developer experience that meaningfully improved reliability, debuggability, or usability for MongoDB engineers.
o You demonstrate readiness for higher level work: taking on more ambiguous tickets, thinking about the broader system impact of your changes, and helping newer engineers onboard to the team's tools and practices.
