Software Engineer, AI SDK at Vercel

This role is ideal for a seasoned TypeScript engineer (5+ years experience) who thrives at the intersection of developer experience (DX) and AI. You should have a deep background in building libraries or tools for other developers and a track record of contributing to open-source ecosystems. This isn't just about building apps; it’s about building the infrastructure that powers thousands of other AI applications. The compensation is highly competitive, starting at $196k with a ceiling near $300k, plus equity. While there is a hybrid core in SF and NYC (Monday, Tuesday, Friday), the role offers true remote flexibility for those living outside commuting distance. You’ll be working at the center of the "AI-native web," giving you massive influence over how the industry explores LLMs and agentic workflows. **You might be a good fit if you...** * Have a portfolio of open-source contributions or experience maintaining public SDKs. * Are obsessed with writing clean, high-performance TypeScript code that makes complex APIs feel simple. * Want to move beyond "using" AI and start "architecting" how developers interact with LLMs. * Prefer a "just ship things" culture with high autonomy and cross-functional collaboration.
