This is a role for the consummate creative technologist who not only designs, but also codes. You will get to directly implement product flows you design, and use the most cutting edge web technologies to push the limits of websites.

Very uniquely at Flint, design is the product. It’s not just about designing our user’s interface. It’s also about designing the design systems the Flint sites rely on - creating a system that at once can reproduce frontends reliably but also one that AI agents can understand.

It’s also about incorporating taste into the AI to produce beautiful websites for our customer’s users.

- Building and maintaining the core frontend application using Next.js and Tailwind CSS
- Implementing design systems and component libraries in Flint website templates.
- Leading UXR sessions, turning user feedback into product feedback seamlessly
- Working closely with the CEO to develop product vision
- Working closely with both founders, all engineers, and solutions engineers in weekly based sprints to bring our vision to life
- Working with our designer to implement and extend Flint's visual identity across our product and the world

## Basic qualifications

- 3-5 years of professional design engineering or frontend engineering experience
- Experience building in React
- Strong portfolio demonstrating web product design skills
- You regularly use AI IDEs like Cursor or Windsurf
- An eye for great website design, as you will be guiding the AI to produce beautiful websites
- Strong communication and upwards management skills
- Comfort collaborating closely and directly with execs and engineers
- Excitement about working full-time, in-person in San Francisco

## Preferred qualifications

- You have built an AI product before
- Experience working in early-stage startups or small teams
- You have a lived understanding of using a website builder (e.g. Webflow or Framer) and/or CMS (e.g. Sanity, Contentful, Strapi)
- Appetite for wearing multiple hats and contributing beyond design when needed
