Senior Backend Engineer (Ruby on Rails), Plan: Knowledge at Gitlab

This role is designed for an experienced backend engineer with deep expertise in **Ruby on Rails** who is eager to bridge the gap between traditional web applications and cutting-edge **AI**. You are likely a senior developer who has managed complex PostgreSQL databases and GraphQL APIs in high-traffic environments. Because this team focuses on "Plan: Knowledge," you should be comfortable architecting systems for content management like Wikis, Markdown editors, and documentation tools. Working at GitLab offers the ultimate in **remote flexibility**, with a culture built around asynchronous work across the Americas, EMEA, and APAC. You’ll be joining an "AI-first" culture where you aren't just building AI features for users (like the Planner Agent and Model Context Protocol integrations), but also using AI tools locally to enhance your own productivity. Perks include equity compensation, flexible PTO, and a dedicated growth and development fund. **You might be a good fit if you...** * Have a mastery of Ruby on Rails, ActiveRecord, and Redis. * Are excited about the **Model Context Protocol (MCP)** and connecting APIs to external AI tools. * Can optimize complex PostgreSQL queries and ensure system reliability during incidents. * Enjoy mentoring others through code reviews and driving technical architecture for a collaborative, global team.
