Molecule and BIO.xyz are building the foundation of Decentralized Science (DeSci) — where biotech meets web3 to make scientific research community-owned, transparent, and faster to market.Molecule provides the infrastructure to turn intellectual property (IP) into programmable, on-chain assets through our IP-NFT framework and evolving protocol stack. This enables researchers, patients, and communities to fund and govern biotech projects in new, open ways.BIO.xyz is the coordination and economic layer of DeSci, powering BioDAOs through funding, governance, and ecosystem alignment.Together, we are creating a new model for scientific discovery — one where breakthroughs are owned and advanced by the communities that believe in them.We’re looking for a senior Product Designer to shape the user experience and visual language of Molecule’s web and mobile products. You’ll turn product goals and complex requirements into clear, intuitive interfaces, and you’ll own the design system that keeps everything we ship consistent.You’ll sit within the Product team and work closely with Engineering and Marketing. You’ll take work from first concept through to pixel-perfect execution and implementation. We move fast, so we value iteration over perfection, quick prototypes over long specs, and designers who are comfortable using AI tools to explore ideas and test them early.This is a role for someone who is as comfortable in a component library as in a whiteboard session. It suits someone who wants to define what great product design looks like in a space where the rules are still being written.WHAT YOU’LL DODesign and refine the user experience and interfaces for Molecule’s core applications across web and mobile, working within the Product team from concept to launchOwn and expand Molecule’s Design System by building and maintaining a scalable, accessible component library that keeps every product consistentDeliver polished, pixel-perfect UI components that improve usability and clarity and stay aligned with our brandWrite clear component documentation, UI specs, and usage guidelines so handoff from design to development runs smoothlyPartner with Frontend Engineers through implementation to make sure what ships matches what was designedApply WCAG standards and UX best practices to make our products inclusive and easy to useBuild interactive prototypes, often with AI-powered tools, to explore ideas and test them with users quicklyIterate on designs based on user feedback, data, and evolving product needsLead and facilitate design work, including setting up frameworks, running brainstorms, and presenting and defending design decisions to stakeholdersContribute to Molecule’s broader visual identity across product and communications, working with external design partners on brand assets where neededWHO YOU AREYou have 7+ years of professional product or UI design experience, ideally on complex productsYou have built and scaled design systems and hybrid component libraries across teams, and your portfolio shows it, including component libraries and detailed UI documentationYou’re a Figma expert with hands-on experience managing a design system in itYou understand HTML, CSS, and front-end frameworks well enough to design for feasibility and speak engineering’s languageYou have a strong grasp of interaction design for both mobile and desktopYou actively use AI tools and AI-enhanced workflows in your design processYou’re ego-free and collaborative. You seek out feedback and critique and keep pushing your craft forwardYou’re self-sufficient. You own the design process end to end, manage feedback, and drive execution without micromanagementYou communicate clearly and can explain the reasoning behind your work to designers, engineers, and leadership alikeNICE TO HAVEYou’ve shipped AI or agent-based product experiencesYou build and test working prototypes yourself, picking the right tool for the question at handExperience with design tokens and front-end design implementationKnowledge of user testing methodologies and iterative research practicesExperience working with external design or branding agenciesBackground in web3, biotech, or decentralised scienceWHY MOLECULEThe chance to define the product experience of a category, building the interfaces through which researchers, patients, and communities fund and govern scienceReal ownership in a young, fast-growing team where your voice shapes both the product and the companyA team that values substance over titles, speed over process, and people who’ve built their way upCompetitive compensation We are an equal opportunity employer.
