We're looking for an experienced Backend Engineer to join the Development Tooling team to help maximize the efficiency and productivity of Git Lab engineers. You'll be crucial in building and maintaining the foundational internal tools, frameworks, and infrastructure abstractions that empower all product developers to write, test, and ship reliable code faster.

This role is ideal for a hands‑on engineer who thrives on solving other engineers' pain points, enjoys working across different technology stacks, and has a passion for improving the software development lifecycle (SDLC).

• Develop Internal Tools: Design, implement, and maintain internal tooling, frameworks & APIs that streamline common developer tasks, such as managing feature flags, automating environment setup, or provisioning internal resources.
• Improve Local Development: Enhance and optimize our local development environment tools and configuration (e.g., containerization setup, dev tooling CLI) to reduce startup time and improve stability for new and existing engineers.
• Performance and Reliability: Investigate and address bottlenecks in the developer workflow, focusing on improving the speed and reliability of different stages.
• Tooling Consistency: Develop and enforce standards and reusable library components for tasks like service communication, configuration management, and health checks across our primary Ruby on Rails and Go codebases.
• Cross-Functional Collaboration: Work closely with product engineers, software engineers in test, and infrastructure teams to understand pain points and translate them into robust, self‑service tooling solutions.
• Documentation and Support: Create clear, comprehensive documentation and provide support for the tools you build, acting as a steward for developer experience.
