UI​/UX Designer, Marketplace

About the Role

Purchasing Platform Inc. is a next‑generation marketplace serving the property management sector. We are looking for a UI/UX Designer for the Marketplace to own end‑to‑end experience design for our B2B marketplace, with a focus on improving conversion and adoption across key journeys (add‑to‑cart, first purchase, second purchase, and ongoing feature usage).

• Own end‑to‑end UX design for the marketplace, optimizing workflows and visual experiences that improve add‑to‑cart, first purchase, second purchase conversion, and feature adoption.
• Design and iterate on key user flows for both B2B and B2C buyers across web and mobile.
• Ensure a consistent, user‑centric experience across the platform grounded in e-commerce and marketplace best practices.
• Identify and flag design opportunities based on user data and platform gaps, bringing recommendations to Product for roadmap consideration.
• Create wireframes, prototypes, user flows, and high‑fidelity mockups to communicate and validate design directions.
• Review legacy UI/UX, identify limitations, and deliver updated designs that address them.
• Deliver production‑ready specs to Engineering with clear annotations and design guidance for implementation.
• Build and maintain a component library, style guide, and design documentation to drive consistency at scale.
• Audit and redesign information architecture to reduce friction, improve discoverability, and support funnel conversion.
• Develop and maintain navigation maps and user flow documentation as a shared reference across Product, Engineering, and leadership.
• Refine navigation structures continuously based on research, analytics, and post‑launch feedback.
• Lead a recurring design review cycle to ensure designs are critiqued and signed off before development begins.
• Define design review checkpoints within sprints (critiques, stakeholder sign‑off, and pre‑launch QA walkthroughs).
• Ensure implementation fidelity through close collaboration with Engineering; track and flag design debt.
• Gather user feedback and synthesize behavioral data (analytics, session recordings, interviews) into actionable insights.
• Benchmark against competitive and best‑in‑class marketplace experiences.
• Support Product in understanding user needs and translating insights into improved experiences.
• Partner with Product Management and Engineering to translate design intent into high‑quality shipped product.
• Participate in sprint planning and roadmap discussions as a design voice—advising on feasibility and effort (not driving prioritization).
• Serve as a design advocate across the organization, helping stakeholders understand and champion user‑centered thinking.

• Funnel performance across key marketplace journeys: add‑to‑cart rate, first purchase conversion, second purchase conversion, and feature adoption.
• Conversion and drop‑off rates on priority buyer flows across web and mobile (B2B and B2C).
• Navigation and information architecture effectiveness, measured by improved discoverability and reduced friction through key paths.
• Design delivery throughput and on‑time handoff, including readiness of wireframes, prototypes, and high‑fidelity designs for engineering implementation.
• Implementation fidelity/design quality, including reduction of design debt and fewer design gaps identified during pre‑launch QA walkthroughs.
• Consistency and scalability of UI, measured by adoption and completeness of the component library, style guide, and design documentation.
• Design review cadence health, including consistent critique/sign‑off participation and clear sprint checkpoints (critique → stakeholder sign‑off → pre‑launch QA).
• User insight velocity, including the rate of actionable insights generated from user feedback and behavioral data that translate into prioritized design improvements.

• Complete designs for the first set of priority work, ready for engineering handoff.
• Establish the overall design direction for the next set of features.
• Complete a legacy UI/UX audit (what’s working, what’s not, initial recommendations).
• Build strong working…
