The ideal candidate has extensive experience optimizing B2B eCommerce websites, high-ticket purchasing experiences, or large product catalog websites and can demonstrate measurable business results from work they personally led.

You should be equally comfortable analyzing customer behavior, interpreting analytics, developing experimentation hypotheses, designing solutions in Figma, collaborating with developers, and measuring business outcomes.

• Partner closely with engineering and stakeholders to prioritize high-impact opportunities that improve customer experience and commercial performance.
• Maintain a consistent, professional, and trustworthy customer experience across a large product catalog.
• Independently identify optimization opportunities rather than waiting for design requests.
• Stay current on B2B eCommerce, customer behavior, conversion optimization, and product design best practices.

• 5+ years of experience designing product experiences for B2B eCommerce, high-ticket eCommerce, or large-scale catalog websites.
• Demonstrated success increasing conversion rate, revenue, average order value, lead quality, or other commercial KPIs through product design and experimentation.
• Strong portfolio showcasing measurable business outcomes, including the problem, your solution, experimentation approach, and results.
• Advanced proficiency with Figma and experience creating developer-ready product designs and design systems.
• Hands-on experience with Google Analytics (GA4), Microsoft Clarity, Hotjar, FullStory, or similar behavioral analytics platforms.
• Experience designing and evaluating A/B tests and making product decisions based on quantitative data.
• Strong understanding of customer psychology, purchasing behavior, usability principles, and conversion optimization.
• Experience collaborating closely with developers to ensure high-quality implementation.
