CLI Engineer

### **About Supabase** Supabase is the Postgres development platform, built by developers for developers. We provide a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. All services are deeply integrated and designed for growth. ### About The Role We are looking for a **Senior CLI Engineer** to join our **CLI Team** and help build a world-class local development experience - while owning a significant share of the **API and backend** work that powers it. This is a hands-on individual contributor role. Technically, expect roughly **80% backend / API work** and **20% CLI work**: most of your time will be on **TypeScript** server-side development, primarily with **NestJS** (API modules, controllers, services, integrations), with a steady commitment to cross-platform CLI quality, releases, and developer experience. You will work closely with customers, product teams, and the open source community to deliver systems that are consistent, secure, and performant - across **Windows, Linux, and macOS** for the CLI, and through well-designed APIs for everything else. This role is ideal for someone who thrives in async, fast-paced environments and wants **depth in backend delivery** without stepping away from **CLI and DX** as a core part of the job. ### **What You’ll Own** - Design, build, and operate backend APIs and services in TypeScript, using NestJS patterns (modules, providers, pipelines) where that is how we ship - prioritizing security, performance, and clear contracts for internal and external consumers. - Design and develop CLI tooling that is consistent, secure, and performant across Windows, Linux, and macOS, aligned with the same platform capabilities the backend exposes. - Collaborate with product and platform teams to define end-to-end behavior: from HTTP/API design through to how the CLI and local development stack surface those capabilities. - Implement unit, integration, and end-to-end tests across backend and CLI so reliability and maintainability stay high as the surface area grows. - Create documentation and help content for API consumers, CLI users, and contributing developers. - Participate in releases, versioning, and backwards compatibility for the components you own. - Monitor usage and feedback; work with customers and the open source community to improve both API/backend and CLI experiences. ### What You’ll Bring - 5+ years of software development experience with a strong track record in backend systems and/or developer-facing tooling. - Strong TypeScript and professional experience shipping production API and server-side code; NestJS experience is strongly aligned with how the CLI Team builds. - Hands-on experience with command-line tools (building, maintaining, or owning CLIs), including cross-platform concerns: filesystem access, subprocess management, terminal UX, and platform-specific behavior. - Proficiency in one or more languages commonly used for CLI and backend work (for example TypeScript/Node, Rust, Python, Go, C++). For this role, depth in TypeScript is essential. - Experience building CLIs with strong user experience: intuitive command structure, clear output, and actionable error messaging. - Familiarity with package distribution and installation (for example npm, yarn, Homebrew, APT, Snap, Scoop, Chocolatey) as they relate to how users install and update tools. - Solid Git workflow and CI/CD experience for automated testing and deployment. Nice to have: - Contributions to open-source CLI tools, libraries, or backend frameworks. - Experience with containerization and orchestration (for example Docker, Kubernetes). - Familiarity with database migration management, Postgres, and related drivers or protocols where they intersect platform or CLI workflows. #### **What We Offer** - **Fully Remote** We hire globally. We believe you can do your best work from anywhere. There are no Supabase offices, but we provide a WeWork membership or co-working
