Staff Product Designer, AI Systems

The Opportunity

Demand.io is a profitable, founder-led consumer AI commerce player driving $1B in annual GMV. We are the team behind SimplyCodes (the #1 AI-powered savings tool) and Product.ai (emerging Axiomatic Intelligence shopping assistant).

We are seeking a Staff Product Designer to operate as a Principal Architect of our user experience. This is a high-leverage position for a "Super IC" who operates as a strategic peer to the Founder. You will not iterate on legacy patterns; you will invent the foundational interaction language for the post-search, AI-native economy. We are pivoting from "Search" (Listing options) to "Adjudication" (Judging truth), and we need a designer to invent the interface for that shift.

What You Will Build

You will not be polishing buttons. You will be architecting the strategic engines of the company.

1. Architect the Conversational Operating System: You will design the 0-to-1 interaction models for our Intelligence Engine (Product.ai). You must solve the "Trust Problem": How does a human interface with an AI that doesn't just chat, but actively adjudicates product quality?
2. Define the "Glass Box" Interface: We reject "Black Box" AI. You will design visual systems that expose the Reasoning Trace of the AI. You will turn complex logic trails into intuitive, verifiable user experiences that build trust without overwhelming the user.
3. Systematize the Design Physics: You will move beyond ad-hoc screens to build a Unified Design System that governs both human and AI execution. You will define the constraints (physics) that allow our interfaces to scale across Web, Mobile, and Agentic surfaces.
4. Execute High-Fidelity Prototypes: We do not trade in static mocks. You will build high-fidelity, interactive prototypes to validate complex state management and conversational flows before engineering writes a single line of code.

Who You Are

We do not care about your pedigree; we care about your character.

• You are a Logic-First Thinker: You view design as a high-IQ discipline, not just decoration. You understand that "Beauty" is the result of maximum efficiency and zero friction. You can debate business logic and growth strategy as fluently as typography.
• You have a Technical Core: You likely have an HCI degree or a technical background. You understand the constraints of the underlying technology (LLMs, Context Windows, Latency) and design with them, not against them.
• You are a "Super IC": You reject the "Director" path that leads to meetings and management. You want to remain hands-on, producing world-class output at high velocity. You are an architect who pours their own concrete.
• You are AI-Native: You do not fear automation; you leverage it. You integrate AI tools into your workflow to multiply your output, allowing you to focus on high-level architecture rather than pixel-pushing.
• You have a "Paradigm Inventor" Portfolio: Your work demonstrates a history of solving novel, ambiguous problems (0-to-1), not just incremental feature maintenance. Your personal site is a signal of your uncompromising standard for craft.

Compensation & Ownership

We operate as a high-performance studio, not a typical corporation. We share the upside directly with the builders.

• Base Salary: $250,000 – $375,000. We target the 80th percentile to attract 1-of-1 talent. Your base covers your life; your equity builds your freedom.
• Profit Participation (PIUs): You aren't just an employee; you are a partner. We grant Profits Interest Units (PIUs), giving you true ownership and a share of the company's operating profit. You earn real cash flow distributions as we grow—not just at a theoretical exit—all within a structure designed for tax efficiency to maximize your take-home wealth.
• Benefits: 100% premium coverage for you and your family, daily catered lunches, and unlimited PTO that we actually expect you to use to recharge.

How to Apply

We don't use cover letters or ATS keyword bots. We measure logic, not keywords.

The Process

1. The Input: Instead of scheduling a 30-minute phone screen, you will answer 5 short questions via video (Async).
2. The Context: These are high-signal prompts designed to test how you prioritize and compress complexity. No rehearsal is required. We value clear thinking over production value.
3. The Trade: If your signal is clear, you skip the generic recruiter screen and move straight to a peer-level conversation with the team.
