Product Design Specialist (UI/UX) — Build a Design System on Next.js/Vercel/Supabase

I run a productized service (columnline.com) serving high-ticket AEC / CRE clients, and I'm looking for a UI/UX & visual design specialist to OWN product design for the core service plus ongoing client work. The product, brand, and style already exist — I grew fast and accumulated some design-system debt. I want someone to punch it up, build systems around it, and make quality consistent across the board. What you'd own: - Build a reusable component library and implement a real design system - Level up the existing product UI/UX and brand consistency - Produce high-quality custom design for client projects on a recurring basis - Enable rapid, high-quality custom solutions for high-ticket clients Stack & tooling: - We work on a Next.js / Vercel / Supabase stack - You should be comfortable using AI tools to move fast — Claude or Codex, plus things like Higgsfield and Remotion - A portfolio is required and will be prioritized Who this is for: This is a deep specialist role — if you live for buttons, hover states, loading screens, icons, spacing, and visual polish, this is your lane. I want tunnel-vision on design quality, not generalists. Who this is NOT for: - Total beginners - GTM engineers / cold email / Make / n8n folks - Dev shops shipping MS PowerApps Please don't pitch me on something else entirely. The deal: - Paid 1-month trial at $1,400 to see what you can do on design - Strong work → ongoing monthly retainer with lots of project volume Fluent English is required. I'd prefer someone with working hours reasonably overlapping U.S. Mountain Time, but it's a preference, not a blocker. To apply, reply with your portfolio and a short pitch.
