You design clean, intuitive, hard-to-misuse APIs and think about the developer on the other side of your interface. * AI-first engineer. You've set up custom automation workflows (e.g., wiring Claude or similar LLMs into forms, APIs, or internal tools to replace manual work). * A self-starter who can take ownership of a project and work independently and collaboratively. * Rigorous about reviewing AI-generated output and taking full ownership of the code you ship. * Good attention to detail and initiative. * Strong written and verbal communication skills - including the ability to document an SDK so another engineer can succeed with it., * Proven experience designing and shipping a developer-facing SDK, library, or public API consumed by other engineers - including the public API/interface design, semantic versioning, and backwards-compatibility discipline that come with it. * Strong separation-of-concerns judgment - able to design framework-agnostic core logic (data, state, domain types) cleanly decoupled from thin, framework-specific bindings, so the same core can support multiple front-end frameworks over time. * Experience packaging and distributing libraries: bundling (e.g., tsup, Rollup, Vite), ESM/CJS output, tree-shaking and bundle-size awareness, and npm publishing. * 2-3 years of professional experience with React & TypeScript, including building reusable, composable components and using strong types as a public contract. * Well-versed in building custom AI automation workflows (LLM API integrations, agentic tooling, or similar). * Solid understanding of fundamentals (HTML/CSS/JavaScript, working with APIs). * Familiarity with standard engineering workflows (PRs, code review, agile). * Strong written communication, including clear technical documentation. * Based in the NYC Metro Area and able to work hybrid from our NYC office 3x per week. * Authorized to work in the US. A Strong Plus * Experience building embeddable / third-party components - style and CSS isolation (shadow DOM or scoped styles), theming and customization, and secure auth/token handling inside a host app. * Monorepo and release tooling (e.g., Changesets, Turborepo, Nx) and automated CI release pipelines. * Backend / full-stack work (Java). * Technical writing and developer documentation experience. ## Related Videos - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Angular Unleashed: Mastering Modern Web Development with Angular](https://www.wearedevelopers.com/videos/685-angular-unleashed-mastering-modern-web-development-with-angular) - [How will artificial intelligence change the future of software testing?](https://www.wearedevelopers.com/videos/85-how-will-artificial-intelligence-change-the-future-of-software-testing) - [WeAreDevelopers LIVE – AI, Freelancing, Keeping Up with Tech and More](https://www.wearedevelopers.com/videos/1786-wearedevelopers-live-ai-freelancing-keeping-up-with-tech-and-more) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) ## Related Articles - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [WeAreDevelopers Dev Digest Issue 116 - The new search wars…](https://www.wearedevelopers.com/magazine/445-wearedevelopers-dev-digest-issue-116-the-new-search-wars) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 122 - Cracks in the polyfill](https://www.wearedevelopers.com/magazine/457-dev-digest-122-cracks-in-the-polyfill)
