Job description

Who We Are:

Therabody ® is the wellness tech leader with a mission to inspire and enable every body to feel, perform and look their best. Therabody ’s product ecosystem includes category-creating innovations in wellness, performance and beauty products, proprietary software and digital content. Not only is it part of our brand ethos to help others, but we are also defining the cutting edge of wellness technology while winning accolades such as Fast Company’s Brands That Matter, Oprah's Favorite Things and the TIME Best Inventions 2025 award. We’re committed to continuous innovation and surround ourselves with specialists, thought leaders, and experts - inside and outside of the office. If you thrive in creative environments, are concerned with big, innovative ideas, love to collaborate, have an entrepreneurial spirit, and are driven to succeed, get in touch with us. Together we can push the limits of what can be achieved for everybody.

Who We’re Looking For:

We’re looking for a freelance UX/UI Designer to drive the creation of engaging, high-converting shopping experiences on Therabody .com. You’ll work hands-on across the full purchase journey—product discovery, browsing, cart, checkout, and post-purchase—translating briefs and business goals into thoughtful, user-centered designs. This is a collaborative, execution-focused role where you’ll partner with our product, engineering, ecommerce, and brand teams to ship work that looks great and performs.

Key Responsibilities

• Own the end-to-end design of the Therabody .com shopping experience across product detail pages, collection and category pages, search and discovery, cart, checkout, and post-purchase — for a global, multi-market storefront.
• Set the ecommerce design direction: define the UX patterns, interaction standards, and quality bar that web PMs and engineers build against.
• Frame the problem before designing the solution — synthesize analytics, session replay, research, and merchandising input into a clear point of view on where the experience is losing customers and what to do about it.
• Partner with the product and analytics teams to build and prioritize an experimentation roadmap; design the variants, define what a win looks like, and read the results honestly — including when your design lost.
• Extend and steward Therabody ’s design system for commerce surfaces: contribute reusable components, document usage, and eliminate one-off patterns rather than adding to them.
• Work directly with front-end engineers on specs, handoff, and design QA — you are accountable for what actually ships, not just what was designed.
• Design within the realities of our commerce platform (Shopify), and make deliberate trade-offs between what is ideal, what is buildable, and what is worth building now.
• Bring design into scoping and roadmap conversations early, so that sequencing, feasibility, and customer impact are weighed together rather than after the fact.
• Run lean, fast research and usability testing to validate direction — and know when a five-user test is enough and when it isn’t.
• Raise the level of design practice across the team through critique, mentorship, and example.

About You

• 7+ years of product or UX design experience, with deep, demonstrable focus on ecommerce — ideally DTC, consumer hardware, or subscription commerce.
• A history of leading significant design work as an individual contributor — setting direction, aligning partners, and raising the quality bar through craft and clear thinking.
• A portfolio that shows real ecommerce depth: product pages, discovery and comparison flows, cart and checkout — with the reasoning, constraints, and outcomes behind the work, not just the final screens.
• Expert in Figma, including building and maintaining component libraries, variables, and design systems at scale.
• Fluent with AI-assisted design tooling and clear-eyed about where it accelerates work and where it produces plausible-looking noise.
• Comfortable working in analytics and behavioral tools — GA4, FullStory, or similar — well enough to pull your own data, form a hypothesis, and defend it.
• Deep familiarity with Shopify or comparable commerce platforms, and a practical understanding of their UX constraints, theme and app ecosystem, and checkout limitations.
• Strong written and verbal communication. You can walk an executive audience through a recommendation, the trade-offs you considered, and the risks you accepted — and hold your position under scrutiny.
• Exposure to conversational or AI-assisted shopping experiences, product finders, or guided selling.
• Experience designing for app and web as a connected ecosystem rather than separate surfaces.
