Product.ai is the truth layer for commerce.
The Role
You'll develop polished, responsive interfaces across three consumer surfaces, ensuring quality and performance while integrating AI components. You will collaborate closely with design to build and extend the design system for a seamless user experience.
Summary Generated by Built In
Product.ai is building the truth engine for shopping. Profitable. Bootstrapped. No outside investors. No board. 25 people outperforming companies 10x our size.
We're hiring a Senior Frontend Engineer.
Why This Role Exists
Product.ai's consumer experience lives across three surfaces - a website, a conversational AI, and a browser extension. Each surface serves verified intelligence in a different form factor. The frontend is where truth meets the user. We need an engineer who can ship polished, fast, trust-building interfaces across all three - and who has the taste to know what "right" looks and feels like without being told.
The System You'll Need to Model
What You Will Own
Who You Are
How We Evaluate
Written artifact. Live URLs to something you built. Or a component library you created. Or a blog post about frontend architecture. Show us what you've shipped. Video screen. How you think about frontend craft, performance, and user experience. Conversation with the founder. Architecture thinking, taste, and how you reason about tradeoffs between speed and quality. Paid work trial. 4 days working on a real Product.ai frontend problem. You'll ship code that goes to production.
Compensation & Ownership
Based in Santa Monica. Hybrid, with flexibility. For the right builder, we're open to remote.

We're hiring a Senior Frontend Engineer.
Why This Role Exists
Product.ai's consumer experience lives across three surfaces - a website, a conversational AI, and a browser extension. Each surface serves verified intelligence in a different form factor. The frontend is where truth meets the user. We need an engineer who can ship polished, fast, trust-building interfaces across all three - and who has the taste to know what "right" looks and feels like without being told.
The System You'll Need to Model
- A locked frontend stack. React 19, Next.js 16, Tailwind v4, shadcn/ui. Non-negotiable. If you have strong opinions about this stack, great - it's already decided, and you'll build within it.
- Three consumer surfaces with different interaction paradigms. A content-rich website. A streaming conversational AI. A browser extension that activates at checkout. Each has different rendering, state management, and performance constraints.
- AI-generated UI components. Parts of the interface are generated or adapted by AI at runtime. You'll work with probabilistic GUIs - components that render differently based on confidence levels, context, and user state.
- A design system that doesn't fully exist yet. The Founding Designer will define it. You'll build and extend it. Design-engineering collaboration is tight - no handoff, no Jira tickets, no waiting for specs.
What You Will Own
- Consumer surface quality. The interfaces users touch. Page speed, interaction fluency, visual polish, accessibility. You ship what users see and feel. The standard is: would you trust this product with your own money?
- Cross-surface component architecture. Shared components that work across web, chat, and extension. Design tokens, component APIs, responsive patterns. The technical infrastructure that makes three surfaces feel like one product.
- AI-interface integration. Streaming responses, confidence indicators, regeneration controls, progressive disclosure. The frontend patterns that make AI intelligence feel trustworthy and responsive.
Who You Are
- How you think. You have taste - an intuitive sense of what "right" looks and feels like. You can defend component architecture decisions with behavioral evidence ("users scan left-to-right, so the action goes here") not just technical arguments. You think about the person using the interface, not just the code rendering it.
- How you work. You ship features end-to-end - from design discussion through implementation through deployment. Claude Code or Cursor is part of your daily workflow. You verify what AI produces. You write code that other engineers can read and extend. You care about performance because slow is broken.
- What you've probably built. Consumer-facing web applications with meaningful traffic. Component libraries or design systems. Streaming or real-time interfaces. We care about the live URL and the craft behind it, not which company logo was on the door.
- Who this isn't for. This role is wrong if you prefer backend infrastructure to user-facing interfaces. It's wrong if "pixel-perfect from a Figma spec" is your primary workflow - there won't always be a spec. It's wrong if you treat Tailwind as optional or have strong anti-React convictions. You'll thrive here if you care about craft, ship fast, and like working at the intersection of design and engineering.

Product.ai Compensation & Benefits Highlights
-
Equity Value & Accessibility — Equity is offered to all team members with profit‑sharing and an annual liquidity mechanism that is framed as recurring, realizable value rather than paper options. Feedback suggests ownership grants and PIUs are positioned as core parts of total compensation.
-
Fair & Transparent Compensation — Pay is positioned as top‑of‑market with published bands on the careers page and clear messaging about elite base salary. External listings reinforce this positioning across senior roles.
-
Healthcare Strength — Core benefits include medical, dental, and vision insurance, with company materials indicating employer‑paid coverage for employees and families. This signals a richer healthcare package than is typical for early‑stage firms.
