Yes, you can build an exciting business AND have real-life real-customer impact. What you'll do Own your product area like a business owner . Track the key metrics that matter for your surface – conversion, engagement, retention, revenue impact – and treat them as your own scorecard, not just your PM's. Proactively surface product gaps and opportunities before they're on the roadmap, and come with a POV on what to build next and why. Own design end-to-end for your product area – from problem framing and early exploration through pixel-perfect delivery – in close partnership with Product, Engineering, Data, and Marketing. That ownership includes understanding the business model, unit economics, and user outcomes well enough to make tradeoffs without a PM in the room. Regularly challenge PRDs before executing : reframe problems, propose alternative solution directions, and push back when the initial framing isn't right. Bring your own data, user insight, or competitive context when you do – not just instinct. Use AI tools to compress the distance between idea and alignment . Build interactive prototypes, functional demos, and testable mockups fast – using tools like Claude Code, Cursor, Codex – so decisions get made on real artifacts instead of static mocks. Shipping a working demo in a day should feel normal. Design highly polished, visually compelling interfaces with a strong point of view on typography, color, layout, visual hierarchy, and motion – across mobile and responsive web. Run rigorous multi-directional explorations before converging, and know how to sell a direction with a well-constructed rationale grounded in user outcomes and business impact – not just aesthetics. Drive design system evolution for your surface area – contributing new patterns, documenting usage, and coordinating with engineering to validate before shipping. Lead and participate in design critiques , giving specific, principled feedback tied to design principles and user outcomes. Hold the detail bar : every interaction, state, edge case, and visual decision is considered before handoff. What we're looking for 6–10 years of product design experience , with a portfolio demonstrating exceptional visual craft and evidence of problem-framing – not just execution. Bonus points if the portfolio shows how your design work moved a metric or changed a product strategy. Fluency in the business layer . You are not just a strong designer. You are a mini-CEO for your product area . You understand conversion funnels, retention curves, and the revenue model well enough to reason about tradeoffs. You don't need to be an analyst, but you do need to care about outcomes beyond task completion rates. A track record of finding problems before they're assigned . You've identified a significant opportunity, built the case for it, and driven it to the roadmap — not just executed on what was handed to you. Comfort operating with autonomy in a fast-moving startup environment — you define the process, not wait for it. That includes knowing when to move fast with a working prototype and when to slow down and pressure-test the problem. Hands-on fluency with AI design, prototyping, and coding tools . You've used AI tools li…
