Product Designer (AI-Native)

Product Designer (AI-Native) Full-time · Contract-to-Hire · Remote · US business hours Level: Mid-to-Senior — 3-7 years Industry: Health tech Start: Immediate Approach: AI-native, non-negotiable THE OPPORTUNITY You're joining at the ground floor of a category-defining moment. 1 in 8 American adults have now taken peptides — and it's going mainstream fast. CollectiveOS is the a subscription peptide business giving members clinician-guided, medical-grade peptide protocols at 50% off retail, sourced from licensed US pharmacies. Built by a team that has helped build three unicorns, including Thrive Market and Function Health. This is a regulated platform operating across 30 states with real obligations to real patients. Members trust us with health information, payment data, and clinical relationships. The backend has to be bulletproof — not because of theoretical risk, but because of those real obligations. This role is the person who makes sure that's true, and who builds the things on top of it. COMPENSATION & TIMELINE STRUCTURE Paid trial to start. Competitive cash compensation from day one. Contract-to-hire — fastest way to find the right long-term fit and let you see us up close. UPSIDE Ground-floor equity. Real equity in a funded D2C peptide startup, riding a category curve that's about to go vertical. The team has helped build three unicorns. You'd be early. TIMELINE Immediate start. We are moving fast. The right person can start within weeks. We will not draw out the process for the sake of process. THE ROLE This is a UX professional who has fully embraced AI development tools — and that combination is what makes the role possible at the velocity we need. The right person works from wireframes — sometimes theirs, sometimes handed to them — drives v0 / Lovable / Bolt to render those wireframes into shipped product, and embraces the back-and-forth of working with AI codegen to get from "almost right" to "exactly right." They own the user-facing product surface end-to-end and iterate on it daily based on what the analytics are saying. The engineering function handles backend, data, and integrations. This role owns everything in between — what the user actually sees, touches, and converts on. Wireframing tools (Figma, Sketch, or your preference) · v0 · Lovable · Bolt · AI codegen tools · PostHog A NOTE ON SCOPE AND SELF-DIRECTION This is a startup. Roles collapse. Lanes blur. We're hiring for a core skill set — UX, conversion craft, AI driven shipping — but the right person doesn't wait to be assigned work. When the core responsibilities are humming, they look sideways: what's not getting done, what's broken at the edges, what would unblock the rest of the team. We don't want someone who needs perfectly-sized tickets handed to them. We want someone who finds the next problem before we know it's a problem CORE RESPONSIBILITIES Product surface ownership · Owns Owns the rendered product surface end-to-end — everything the user touches and everything the team uses to run the business behind the scenes. Takes wireframes and drives AI codegen tools to render them into shipped product on top of our existing stack. When the AI gets stuck, you keep iterating with prompts until the layout is right. The bar is the user experience that ships, not how it got there. Wireframe-to-shipped UI · v0 / Lovable / Bolt workflows · responsive across desktop and mobile · component consistency across modules UX design and conversion craft · Owns Owns the user experience of every flow that touches a member or prospect. Designs for conversion, not for portfolio screenshots. Treats wireframes as hypotheses to be tested, not artifacts to be defended. Every drop-off in a flow costs real revenue, and the right person feels that. Wireframing · interaction design · accessibility · funnel-aware UX · design system stewardship AB testing and iteration · Owns Designs and ships AB tests on landing pages, order flow steps, and member-facing surfaces. Works directly with marketing on attribution and event instrumentation through PostHog so every test produces a clean readable result. Iterates fast — the analytics tell you what to do, you ship the next version, you measure again. Variant design · PostHog event design · split-test design · landing page iteration · cross-channel UI consistency Wireframe-to-shipped pipeline · Owns Owns the pipeline from wireframes to the staged build. When a wireframe changes, the staged build reflects it within hours, not weeks. Reviews AI-generated output against design intent and iterates with prompts until it matches. The bar is design fidelity to the wireframes without slowing the team down. AI codegen prompt iteration · component review · staging approval flow · visual regression review Cross-functional collaboration · Contributes Works alongside marketing on landing pages, opt-in flows, and channel-to-website handoffs. Works alongside the backend function on what data the UI needs and how it should be shaped. Works alongside the design function on brand consistency. Doesn't own marketing strategy, doesn't own backend architecture, doesn't own brand — but communicates clearly across all three so nothing gets stuck. Marketing landing pages · data and API needs articulation · brand voice consistency · cross-team async hygiene HOW SUCCESS IS MEASURED • Conversion rate — member journeys complete at higher rates over time • Ship velocity — wireframes reach staging the same week, not the same month • Test cadence — number of clean AB tests live each month, not stuck in design • Design fidelity — shipped product matches wireframe intent without manual cleanup • Cross-team latency — marketing and engineering get unblocked, not blocked • Member-reported quality — member experience scores improve over time MUST-HAVE QUALITIES Mindset and approach • AI-native — uses AI codegen tools as a daily driver, not a curiosity. Tool of choice doesn't matter; fluency does • Embraces the back-and-forth of working with AI codegen — patience and craft, not frustration • Thinks in funnels and conversion, not in portfolio polish • Direct and async-friendly — fits a small team where everyone has skin in the game • Excited about peptides, longevity, and consumer health — or fast to get there Design and craft skills • Strong visual and interaction design portfolio — consumer-facing product preferred • Fluent in modern wireframing tools (Figma, Sketch, or your preference) at a professional level • Demonstrable AB testing and conversion design experience • Mobile-first instincts — most members will arrive on a phone • Native mobile app design experience a plus — we're web-first today, but a native app is on the roadmap and someone with iOS/Android design instincts will have a head start • Strong brand and visual instincts a plus — there's room to contribute where it overlaps with product design AI tool fluency • Has shipped production work via AI codegen tools — v0, Lovable, Bolt, or equivalent • Knows how to prompt iteratively to get from 'almost right' to 'exactly right' • Reviews AI output critically against design intent, not just for visual polish If this sounds like the right fit, we'd love to hear from you. We're looking for someone who is genuinely excited about the peptide space, ships when others are still wireframing, and wants to build something meaningful from the ground floor with a team that has done it before.
