Job description

Frontend Senior Remote Remote, US (Mon, Tue and Fri in office if within commuting distance of SF or NYC)

You own product design and frontend implementation for Vercel's AI Gateway, which connects apps and agents to hundreds of AI models with one API key. You design and ship the journey of choosing a model, making a first request, diagnosing a failed one, and handling routing, budgets, credentials and security controls across the website, dashboard, CLI and API responses. There is no required path into the role; what counts is work you identified, built and shipped yourself. Base pay is $208,000 to $312,000 in San Francisco.

Why this role fits

It fits a service builder who has carried a product alone from planning through screens, code and post-launch metrics. The posting expects you to use coding agents daily while still explaining, testing and owning the code they help produce, and it favors experience with developer tools or AI model services. If you live in the US far from an office, the role is fully remote.
