An overview of this role

As a Backend Engineer joining our team, you will work on the foundational layer of GitLab Continuous Integration (CI). Our team is largely involved in scaling CI, along with ensuring our CI features remain performant and reliable by driving improvement to critical database infrastructure.  As many of our efforts are Engineering led, you will also have an opportunity to provide input towards our CI data management strategy. 

About the team

The CI Platform group was created in 2024, as part of the Verify stage, upon evaluating that we needed a dedicated team to work on the operational aspects of GitLab CI to ensure our platform remains best-in-class. The team has been largely focused on partitioning CI/CD Data and has started to explore aspects of CI Data retention and improved data management. You will get to dive into some complex technical challenges and collaborate with our infrastructure teams to strategize on solving these exciting challenges related to how we scale and grow CI.  More details can be found in our technical roadmap for Verify.

We live our transparency value by designing our systems and planning our work with publicly facing artifacts.  Some examples of our work include: 

• CI/CD data time decay: design document, planned work
• Partition CI/CD pipelines data
• Design CI data retention policies for gitlab.com
• Improvements to Sidekiq Worker performance

What you’ll do  

• Implement performance and scale improvements for GitLab CI in a fast-paced, iterative environment.
• Collaborate with other stakeholders within Engineering (e.g. other Database or Infrastructure teams) to set best practices in managing a sustainable platform and to maintain a high bar for quality.
• Advocate for improvements to reliability, security, and performance.
• Craft code that meets our internal standards for style, maintainability, and best practices for a high-scale web environment. Maintain and advocate for these standards through code review.
• Recognize impediments to our efficiency as a team (“technical debt”), propose and implement solutions.
• Ship small features and improvements with minimal guidance and support from other team members. Collaborate with the team on larger projects.
• Work with your team to assess technical feasibility and discuss how best to iterate on complex problems. This might involve working on proof-of-concept proposals to help guide technical discussions.
• Take ownership of what we build, focusing on stability and availability.

What you’ll bring

• Professional experience with Ruby on Rails and PostgreSQL.
• Experience working with a platform or complex application (Large scale is a bonus).
• Familiarity building and deploying software with CI/CD or other internal tooling. 
• Familiarity with distributed, scalable and reliable systems.
• A user of modern DevOps platforms. (GitLab is a bonus.)
• Proficiency in the English language, both written and verbal, sufficient for success in a remote and largely asynchronous work environment.
• Experience working in a highly agile, iterative software development process.
• Self-motivated and self-managing, with excellent organizational skills.
• Demonstrated ability to work closely with other parts of the organization.
• Share our values, and work in accordance with those values.

How GitLab will support you

• Benefits to support your health, finances, and well-being
• All remote, asynchronous work environment
• Flexible Paid Time Off
• Team Member Resource Groups
• Equity Compensation & Employee Stock Purchase Plan
• Growth and development budget
