Design, implement, and optimize systems for automated artifact creation, update, validation, vulnerability scanning, remediation, and SBOM and provenance generation for npm packages
Build and maintain internal developer tools: bundler plugins, CLI utilities, code generators, and meta-tooling that improve the workflows for library and package maintenance
Develop and debug integrations for modern JS build systems and package managers
Solve complex dependency resolution issues, manage monorepo orchestration, and drive improvements in infrastructure automation

Qualification
Required
8+ years building and maintaining infrastructure for JavaScript/TypeScript package ecosystems (npm) or large-scale open-source projects in a similar domain

Deep familiarity with modern JS build tooling: esbuild, Rollup, Webpack, Vite, Bun, SWC, Turbopack, Babel, PostCSS, Rome/Biome, Deno, and the associated tradeoffs between ESM/CJS/modules
Hands-on experience orchestrating large monorepos (Lerna, Nx, Turborepo or custom setups) and solving infra-scale dependency or module resolution problems in production
Comfortable working with build system code written in Go (our infra is Go-based), plus solid experience in JavaScript/TypeScript. Other language ecosystems are a strong plus
Demonstrated ability to debug and resolve critical infrastructure and package-building failures at scale
Experience with cloud-native technologies and infrastructure, including containerization (e.g., Docker, Kubernetes), cloud services (e.g., GCP, AWS), infrastructure as code practices (e.g., Terraform)
Excellent cross-team communication skills: can collaborate with product, engineering, ops, and security teams; proactively document, mentor, and share lessons learned
Preferred
Active contributor to the open source JavaScript ecosystem tooling community
