Senior Product Designer

The one design hire. End-to-end owner of how verified truth looks, feels, and behaves — a builder whose leverage is taste and judgment, not throughput.

Product.ai is the verified truth layer for shopping — the intelligence that tells you what's actually true about a product, including when not to buy. Profitable. Bootstrapped. No outside investors. No board. 20 people outbuilding companies 10× our size.

Strong people find us and keep finding us — they apply over months and years, because the field moves fast and the exact profile we need moves with it.

Design here has been held to a founder-level bar from day one — because when the product is trust, the interface is the product. That bar now needs its full-time owner.

This is the one design hire: end-to-end ownership of every surface a consumer touches, with a direct line to the founder and nothing between your judgment and what ships. You sit at the decision table, model where the company is going, and design ahead of it.

It's a builder-owner seat, and that's the point. You own the work from strategy to pixels yourself — strategy reaches the product through your judgment, not through a brief someone else writes — and your leverage is taste: you decide what to make and how you'll know it landed. You can take an idea from "what should a verdict feel like when the evidence is mixed?"

to a rendered, working component the same day.

• Decision-shaped truth. The core interface unit isn't a chat reply or a product page — it's a verdict: what's true, the evidence behind it, how confident we are, and when the honest answer is "don't buy." Users reshape the question — change a constraint, a budget, a skin type — and watch the verdict change in front of them. The verdicts come from Axiomatic Intelligence (ADP), our patent-pending verification research method.
  
  Designing calibrated trust — never overselling certainty, never burying it — is the craft.
• A design system that is law, not a guideline. Your tokens and components are consumed directly by the agents that generate our UI, so ambiguity in the system becomes defects in the product. The system has to be precise enough to govern machine output, not just guide human designers — and visual mockup gates every build, fired before engineering writes production code, enforced by the system rather than by goodwill.
• A company that redesigns itself continuously. Strategy, surfaces, and systems move weekly, and agents do the moving — they answer their own questions against our shared knowledge base instead of waiting on you. You model where the product is heading and design ahead of it, working from signal rather than briefs.

If reading that energizes you, keep going. If it feels overwhelming or under specified, this isn't the right fit.

• The design system as governing law. More than a component library with usage notes — a system precise enough that agents generate inside it on every surface. You own its precision, its evolution, and the gates that keep generated output within it.
• The mockup-before-code gate. Every build passes a design gate before engineering: the visual mockup is approved before production code is written. The gate is enforced, not aspirational, and you own what passes. Most of this job is good calls in the gray area — your taste is the standard the gate applies.
• Design exploration at machine scale. You'll direct agents to render dozens of real, rendered directions where a traditional process produces three — then decide which live and which die. Compute is effectively unlimited and steered by return, not cost: the expensive thing is a redo cycle, never tokens.
• The consumer experience bar. End-to-end quality on everything a consumer touches — web, extension, chat, mobile — each owned as a falsifiable outcome with an evidence test a stranger could run. It's the part any company would need, here with the whole surface area and yours alone to carry.

You independently form working models of complex systems, notice where your model is wrong, and update fast. You start from enough signal to reason from first principles, and you move…
