Every piece of art deserves to be seen.

Smartist is the leading art visualization app, with over 1M downloads across 175 countries and a 4.8★ rating. Artists use us to turn their work into photorealistic mockups in seconds, then sell it.

Now we're building Smartist Studio: the all in one platform for the whole art business. Everything around the art, so artists can get back to the art. We're looking for a React engineer to build it with us.

What you'll do

• Build and ship the Smartist Studio web app in React and TypeScript
• Turn Figma designs into interfaces that feel fast, clean, and obvious. Our users are visual people with high standards
• Work directly with design, product, and the iOS team. Small company, short feedback loops, your work goes live within the week
• Own features end to end, from spec to ship to the analytics that tell you if it worked

• Keep the codebase healthy through reviews, tests, performance work, and accessibility

   

What we're looking for

• 2+ years building production React apps with TypeScript
• Strong fundamentals: hooks, component design, state management, data fetching
• You care how it looks. Pixel accuracy, responsive layouts, motion that feels right
• Comfortable with Git, code review, and shipping in small increments
• Clear communicator in English, ready to work remotely

Nice to have

• Next.js, React Native, or Tailwind
• Canvas, WebGL, or image manipulation in the browser
• Experience building AI powered features
• Design system instincts and fluency in Figma
• You make things outside of work too

Why Smartist

• Work from anywhere. Fully remote, flexible hours. We care when you ship, not where you sit.
• Ownership. You're joining as Smartist Studio is being built. You'll shape the frontend architecture, the component system, and how the whole thing feels, rather than maintaining someone else's decisions.
• Impact. Your work ships to artists in 175 countries, on a product rated 4.8★. We release weekly, so you see it live within days.
• The intersection of art and technology. Our users are painters, photographers, sculptors, and gallerists. The work is visual, and the standard is high.
• AI that supports artists, not replaces them. That principle is non negotiable here, and it shapes what we build.

• Competitive salary based on experience, plus [paid time off, learning budget].
