AI UX Product Designer

AI Design Engineer

Location: Remote. Company has an office in the Miami / Ft. Lauderdale area.

Compensation: Competitive base and meaningful equity in a rapidly growing startup. Full-time preferred; open to contract-to-hire for an exceptional builder.

Some people can design a beautiful interface. Some people can build one. We are looking for the rare person who does both, does both fast, and treats AI tools as a natural extension of how they work.

Phoenix is the Autonomous Commerce Platform for DTC founders. We unify storefronts, checkout, payments, and operations into one AI-native platform where agents handle the operational grind and merchants focus on growth: making the most money, with the least headache, on their own terms.

We set out to build the "Shopify of Direct Response," and along the way we recognized something bigger. Direct response is roughly a third of all ecommerce transactions, a trillion-dollar market chronically overlooked by Silicon Valley. The merchants who run it are obsessive about tooling. They live and die by velocity, conversion, and margin. They have no brand moats, so they compete purely on operations, which is exactly what makes them the earliest and fastest adopters of AI agents in commerce.

This is a category-defining bet, and we are running at it from a position of strength.

• 8-figure ARR, growing 100%+ YoY (top 0.5% of all startups launched in 2024)
• Rapid merchant adoption and expanding market presence
• Industry-leading NPS score
• 70% of our new deals come as referrals from existing merchants
• We've activated more merchants in Q1 2026 than in the previous two years
• Venture-backed by operators and investors with a track record of building and scaling category leaders

We out-execute the legacy platforms because we behave like a Silicon Valley technology company. Most of our competitors are cash cows: less professionally run, with limited innovation in over a decade. We bring real professionalism and pace to a space that has grown complacent.

Our merchants live and die by conversion rate, and so does our UI. For them, design quality is not aesthetics; it is revenue. Every screen we ship either makes a merchant money or costs them money, and they can tell the difference within a day.

Our product team gets new pages roughed out and wired against our component library fast. What we do not have is the person who takes those pages from working to great: the layout, the flow, the small moments that make software feel effortless. That person works in code, not only in Figma, and ships.

Here is the loop. Our product lead sketches the first idea of a new page and wires up the logic. You take it from there and own the outcome: how it feels, how it converts, whether merchants can use it without thinking. Then we put it in front of merchants, you hear what they say firsthand, and we go again. If the wiring is wrong for the merchant, say so and fix it.

You are in the merchant conversations, not reading a summary of them.

This is not a marketing or brand design role; we have someone great for that. This is hardcore UX and front-end, with the taste of a designer, the hands of an engineer, and the instincts of a PM. The last part is not a bonus here; it is part of the job.

• How the product feels. Turn first-pass pages into polished, production-ready UI, and design and build new flows end to end, from idea to shipped, on our Storybook component system.
• The merchant's reality. Sit in on merchant calls and demos, read the support tickets, watch the session replays, and turn what you learn into design decisions. You know our top merchants by name and what each one is trying to do this quarter.
• The numbers your…
