UI​/UX Designer, Marketplace

We’re transforming property tech! Purchasing Platform Inc. is a next generation marketplace serving the property management sector. Leveraging our market knowledge and tech savvy, we revolutionize the procurement of products and services across the sector. By centralizing procurement, our software brings stronger corporate controls and greater spend visibility to portfolio operators of all sizes.

Purchasing Platform is seeking a UI/UX Designer, 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). In this role, you’ll design and iterate on core buyer workflows across web and mobile, balancing strong visual execution with practical, user‑centered UX grounded in e‑commerce and marketplace best practices.

You’ll create wireframes, prototypes, user flows, and high‑fidelity mockups, then deliver production‑ready specs to engineering with clear annotations and guidance. You’ll also lead efforts to improve navigation and information architecture, build and maintain design documentation (including a component library/style guide), and establish a repeatable review cadence to ensure high‑quality design decisions and implementation fidelity.

This is a highly cross‑functional role partnering closely with product and engineering, using user feedback and behavioral data (analytics, session recordings, interviews) to identify gaps and bring recommendations forward for roadmap consideration.

• 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.
