As an Intermediate Backend Engineer on the Plan:
Knowledge group, you’ll help turn Git Lab from a “useful documentation tool” into a truly collaborative knowledge solution that lives right next to where teams plan, code, and deploy. You’ll focus on making our Ruby on Rails backend solid, scalable, and a pleasure to build on, powering products like Wiki, Pages, Markdown, text editors, and the Git Lab Query Language (GLQL).

You’ll spend most of your time in Rails and Graph

QL, collaborating closely with frontend engineers, Product, UX, and Security to design APIs that are easy to use, build performant query engines, improve reliability and test coverage, and support features that work well for both technical and non-technical users in a highly async, all-remote environment.

• Building fast, flexible query engines that make complex knowledge easy to find and use through GLQL
• Designing and scaling APIs that support rich text and Markdown collaboration for 100,000+ organizations

• Develop and maintain backend services in Ruby on Rails that power Wiki, Pages, Markdown, text editors, and Git Lab Query Language (GLQL) features.
• Design, implement, and evolve Graph
  
  QL APIs that are intuitive for frontend engineers to consume and support scalable, performant user experiences.
• Improve reliability and performance across the stack by profiling, diagnosing, and resolving bottlenecks in application code, Postgre
  
  SQL queries, Redis usage, and background jobs.
• Write automated tests with RSpec and contribute to improving test coverage, helping prevent regressions and ensuring safe, incremental changes.
• Collaborate closely with frontend engineers, Product, UX, and Security to break down large projects into small, shippable iterations and deliver them end to end.
• Review merge requests, give and receive constructive feedback, and champion code quality, maintainability, and consistency across the codebase.
• Contribute to technical documentation so that features, systems, and decisions are clearly documented for both technical and non-technical Git Lab team members.
• Investigate and debug production issues, participate in blameless incident reviews, and implement follow-up improvements that strengthen system resilience.

• Proficiency in Ruby on Rails and core backend components such as Active Record, Redis, and HAML.
• Experience designing, implementing, and maintaining APIs, ideally including Graph
  
  QL, with attention to usability and clarity for frontend teams.
• Practical experience with relational databases like Postgre
  
  SQL, including querying, modeling, and basic tuning.
• Habit of writing automated tests with tools like RSpec and building reliable, maintainable code with strong attention to performance and scalability.
• Experience using Git in a professional setting, contributing via merge requests, and participating in thoughtful…
