Company mission
To separate genuine product knowledge from the flood of AI-generated marketing noise now dominating the internet.
Role
Who you are
- Comparable experience: a senior design engineer or frontend engineer with real design taste and an HCI background, a principal/senior product designer who ships their own production React code, or someone who designed and shipped a consumer product end to end
- How you think. You see a screen as a system: what state it's in, what it's telling the person, and where friction hides. You think about the person on the other side of the screen the way a human-computer interaction education teaches: what they're trying to decide, what they can perceive, and how layout, typography, and motion earn their trust
- How you work. A design tool, a coding agent, and a browser open together, most of the day. You use AI tools as force multipliers for design and code, and you verify every detail because you can build it by hand
- What you've probably built. Interfaces real people used, that you can show live and say what you decided and why: a product people trusted with a decision, a design system other engineers built inside, a prototype that became the shipped production surface. The portfolio is more important than the resume
- Who this isn't for. This is wrong if you want to be handed finished designs to implement, or finished code to style; here both halves are yours end to end. It's wrong if you want a traditional design-management bureaucracy instead of building directly alongside our Founding Designer and the founder. You'll be happiest here if you want your work in front of real shoppers every day and you'd rather ship the live interface than present a slide deck
What the job involves
- We need a senior builder who takes consumer interfaces from design exploration to live production code with zero handoff, and who co-owns the `/shop` Design Record and design system in code
- You are senior: you've shipped interfaces people love, you have a real human-computer interaction background, and your portfolio shows taste a stranger can see immediately
- You partner directly with our Founding Designer and the founder to set and raise the consumer design bar across every surface
- The part that makes this different from a traditional frontend or design seat: our design system is executable law, not a guideline
- Its tokens, components, and motion physics in the `/shop` Design Record are read directly by the coding agents that generate our interfaces, so precision in the design system governs the entire product
- The Verification Checker and a conversational surface that shows its work. Whether a shopper pastes a recommendation into the Verification Checker or asks a shopping question in chat, the interface grades claims across five verification states, streams citations, and lets a person inspect the evidence beside the verdict without losing the thread. Streaming state, interruption, and motion physics are design decisions, not plumbing
- Decision-shaped interfaces. The unit of every surface here is a verified answer and how sure we are of it. Confidence has to render as credible, never oversold and never buried, and that's motion, state, and typography doing trust work
- The `/shop` Design Record and a design system agents build inside. Master tokens, a canonical component catalog, and usage rules precise enough that coding agents generating a screen stay within the bar
- Prototypes that are the real thing. The design-to-engineering handoff is gone here. A direction is explored as a working prototype in a design tool and in production React/TypeScript in the same session, and the winners ship live
- Cortex, the shared AI brain the company runs on. You work inside it daily, directing coding agents as force multipliers the way our founder does, and since August any operator here can change the rules the company runs on, live, without waiting on founder approval
- Partnering directly with our Founding Designer and the founder to set and raise the consumer design bar. You co-own the visual, interaction, and motion bar across our consumer surfaces — taking directions from sketch or interactive rig to shipped production code with zero handoff
- The `/shop` Design Record and design system in code. You own the canonical master components, tokens, motion physics, and rules that govern our consumer interfaces and coding agents across `/shop`, the Verification Checker, SimplyCodes, and the browser extension
- Live production interfaces, end to end. Design and code for the Verification Checker, the conversational shopping assistant, and its evidence side panel: how a verdict renders across five verification states, how proof opens beside it, how streaming and state transitions feel in the hand, and how our frontend architecture composes them cleanly in React and TypeScript
- The polish and motion physics layer. Motion, state, spacing, typography, and micro-interactions: the thousand small decisions that make a trust interface feel unmistakable
- Your seat charter. Within your first quarter you co-sign a charter for this seat. It names one machine-checkable number that proves the seat is working, and a high-ownership partnership model with our Founding Designer and the founder
- The craft you must already own: a real human-computer interaction background, not a gloss of design vocabulary; a very strong design eye, proven by a live portfolio of shipped work; building interfaces in React, TypeScript, and CSS at production quality; fluency in Figma; motion physics and state designed on purpose; and AI coding and design tools as force multipliers you verify by hand
Application process
- Async video screen (or Fast-Track Portfolio/GitHub review). About 15 minutes, on your own time, replacing the recruiter screen — or, if you have a standout live portfolio of shipped interactive work and GitHub repos, share those links directly on your application to fast-track straight to our stakeholder and founder conversations
- Calls with company stakeholders. Short conversations with the people you'd build beside, including our Founding Designer
- Conversation with the founder. How you see a screen, how you use your tools, and what you'd elevate first across the Verification Checker and `/shop`
- Paid work trial (`PRJ-75`). A paid real-work trial in our environment: taking a live `/shop` Verification Checker or consumer interface from direction to shipped production React/CSS inside the `/shop` Design Record. We look for visual taste, motion physics, how you use AI tools as force multipliers, and how we collaborate together
- If the work above sounds like yours but your resume is unconventional, apply anyway. We hire on the work and the reasoning, not the pedigree
Our take
Artificial intelligence has come on strides in recent years, but many assistants still struggle with relatively simple tasks. For example, AI-powered shopping assistants have frequently been found to supply conflicting information regarding prices, product specifications and more.
Product.ai is building what it calls the verification layer for AI commerce, to combat inaccurate and misleading product overviews. The platform can do things like check whether coupons actually work, verify the latest prices, and decipher whether claims about products are true.
Formerly known as Demand.io, the company's earlier focus was on creating innovative eCommerce experiences, but its rebrand to Product.ai in 2026 cemented its pivot to creating the truth layer for eCommerce. This mission answers a growing problem for consumers, as increasing AI marketing noise drowns out true reviews - meaning there should be ample opportunity for Product.ai to make an impact.
