Job description

About Vercel:

Vercel gives developers the tools and cloud infrastructure to build, scale, and secure a faster, more personalized web. As the team behind v0, Next.js, and AI SDK, Vercel helps customers like Ramp, Supreme, PayPal, and Under Armour build for the AI-native web.

About the Role:

The v0 team is a fast-moving group within Vercel focused on building the future of UI development with AI. We’re working on v0.dev, a cutting-edge generative design tool that turns natural language into functional, beautiful React components using Tailwind CSS, leveraging large language models and novel research in human-AI collaboration.

If you’re based within a pre-determined commuting distance of one of our offices (SF, NY, London, or Berlin), the role includes in-office anchor days on Monday, Tuesday, and Friday. If you're located beyond that distance, the role is fully remote. For location-specific details, please connect with our recruiting team.

What You Will Do:

As an AI Engineer, you'll sit at the intersection of machine learning, product development, and frontend engineering. You’ll work closely with product designers, ML scientists, and full-stack engineers to prototype and deploy innovative systems that redefine how developers and designers build interfaces.

Your responsibilities include:

• Designing and developing prototypes that explore new interaction paradigms powered by LLMs.

• Researching and implementing state-of-the-art models and prompting strategies for UI generation and code synthesis.

• Collaborating on building and fine-tuning internal tools, datasets, and evaluation pipelines.

• Running A/B tests and user experiments to validate hypotheses and improve generation quality.

• Bridging the gap between research and production—bringing cutting-edge techniques into a stable and scalable environment.

About You:

We’re seeking a creative and practical thinker who thrives in ambiguity, loves building with AI, and has an eye for design and developer ergonomics.

You may be a good fit if you have:

• 5+ years of experience in research engineering, applied ML, or related fields.

• Strong programming skills in Python and JavaScript/TypeScript.

• Experience working with or fine-tuning LLMs (OpenAI, Hugging Face, etc.).

• A solid understanding of modern frontend technologies (React, Tailwind, etc.).

Benefits:
