About the Role

You'll own design end to end: the consumer trade-in experience on sellit9.com, the embedded flows our merchant partners run on their own storefronts, and the design system that keeps it all consistent. The role is deliberately a product and design hybrid: you'll help decide what we build and why, then design how it works, working directly with the CTO, engineering and product. Your work ships to production every day.

This isn't a "make it pretty" role. You'll live in the conversion data, watch real user sessions, and defend every design decision with evidence. You'll also design for a surface most designers haven't touched yet: our trade-in flow runs inside Claude through our AI connector, and you'll help define what commerce looks like when the customer brings an AI agent to the journey.

What You'll Do

- Own product problems end to end: framing, specs, flows, prototypes, high-fidelity UI, and production handoff, prioritizing with the CTO and following the metric after launch.
- Design and iterate on the consumer funnel (quote, checkout, confirmation) and the email reminders that pull sellers back, to raise conversion.
- Design merchant-facing surfaces: embedded trade-in flows, white-label experiences, and partner dashboards.
- Own our design system in code, and keep the Figma library in step with it rather than the other way round.
- Design in code: vibe-code prototypes with coding agents (Claude Code, Codex, or similar) so ideas get tested as working software, then ship the real thing.
- Package our brand and design rules as agent skills, so every AI workflow on the team produces on-brand output by default.
- Run our asset pipeline: hero videos built in Remotion,



page imagery generated under locked brand styles, everything versioned like code.
- Run usability tests and dig through GA4 and Microsoft Clarity to find where users struggle. Small team, many hats: brand, marketing assets and landing pages when needed.

- Have 5+ years of product design experience with shipped, conversion-focused work in e-commerce, marketplaces, or fintech.
- Have product sense beyond the pixels: you can write a spec, scope an MVP, argue a prioritization call, and own a metric.
- Build, don't just spec. You ship production-quality React with AI assistance, and your work lands in the repo as a pull request rather than as a handoff.
- Work AI-natively, and in git. Coding agents (Claude Code, Codex, or similar) are already how you build every day: you vibe-code explorations, generate your own skills and custom agents, and keep prompt libraries you reuse. This is non-negotiable.
- Treat Figma as a thinking tool, not the deliverable. Your design lives in git - not only …
- Have design systems experience: you've built or owned one and kept it consistent and accessible across web and mobile.
- Are fluent in funnel metrics: conversion rates, A/B testing, session replay analysis, and the discipline to let data settle debates.
- Do hands-on user research, and write robust UX copy.

Even better if you have

- Experience designing AI-powered products: chat or agent interfaces, conversational commerce, or prompt-driven UX.
- Experience wiring design tools to agents: Figma MCP, Code Connect, or your own scripts.
- B2B2C or white-label experience: one product, many brands, strict theming constraints.
