About the role

Senior CLI Engineer developing backend APIs and CLI tooling for Supabase platform. Collaborating on cross-platform tools to enhance developer experience.

Responsibilities

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.

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.
Contributions to open-source CLI tools, libraries, or backend frameworks (nice to have).
Experience with containerization and orchestration (for example Docker, Kubernetes) (nice to have).
Familiarity with database migration management, Postgres, and related drivers or protocols where they intersect platform or CLI workflows (nice to have).
