Backend Engineer - Memory

Department: Enablement

Apply now
This position is remote based.
At GitLab, developers are independent and self-organized individual contributors who work together as a tight team in a remote and agile way.
Most backend developers work on all aspects of GitLab, building features, fixing bugs, and generally improving the application.  The Memory team is responsible for optimizing GitLab application performance by managing the memory resources required. The team is also responsible for changes affecting the responsiveness of the application.
The Memory team is responsible for optimizing GitLab application performance by managing the memory resources required. The team is also responsible for changes affecting the responsiveness of the application. We will accomplish these goals in two ways. First we will research and resolve reported memory issues to the best of our ability and within our published SLAs. Additionally, will build tooling to proactively inform developers of the static and dynamic memory consumption of their proposed changes.


  • Identify, troubleshoot, improve and manage memory-intensive aspects of the GitLab application.
  • Explore alternatives outside of the GitLab application for reducing memory consumption through contributions to, e.g., Rails, Ruby, Puma, or other key third-party components.
  • Define and help implement best practices for creating efficient and performant code.
  • Setting standards that changes are not affecting memory utilization and can be validated.
  • Partner with the Quality team to maintain effective performance reporting and monitoring through instrumentation and testing.


An ideal engineer candidate -

  • Proficiency in the English language, both written and verbal, sufficient for success in a remote and largely asynchronous work environment
  • Demonstrated capacity to clearly and concisely communicate about complex technical, architectural, and/or organizational problems and propose thorough iterative solutions
  • Experience with performance and optimization problems and a demonstrated ability to both diagnose and prevent these problems
  • Comfort working in a highly agile, intensely iterative software development process
  • Demonstrated ability to onboard and integrate with an organization long-term
  • Positive and solution-oriented mindset
  • Effective communication skills: Regularly achieve consensus with peers, and clear status updates
