We’re looking for a Product Designer to own the end-to-end product experience across guest-facing and restaurant-facing products. Your primary focus will be product design, the design system, and a scalable multi-brand experience. You will work directly with Product and Engineering, with occasional support for client launches and commercial materials.

This is a high-autonomy individual contributor role, so we’re looking for someone who can frame problems, make informed trade-offs, deliver implementation-ready designs, and verify the quality of what reaches production.

• Use AI-assisted tools where they improve research, exploration, prototyping, content adaptation, or repetitive production work; validate the resulting UX and code rather than accepting generated output uncritically.
• Occasionally support the Eatery Club website and commercial materials when product priorities allow.

What We’re Looking For

• 3+ years of commercial Product Design or UI/UX experience
• Portfolio showing shipped digital products and the reasoning behind key decisions.
• Experience building or evolving component-based design systems in Figma.
• Ability to work from an ambiguous problem through discovery, design, handoff, and implementation QA.
• Experience collaborating directly with engineers and making scope–quality trade-offs.
• Ability to prioritize independently as a senior individual contributor.
• Practical experience using AI-assisted tools, with at least one example explaining what was automated, what remained a human decision, and how quality was validated.
• English sufficient for working with international clients and partners

Experience with white-label or multi-brand products will be a strong advantage.

• White-label, multi-brand, B2B SaaS, HoReCa or restaurant-tech experience
• Kiosk, touchscreen, mobile and responsive web experience.
• Accessibility and multilingual product experience.

Why Join Eatery Club

• Work on products already used across 10+ markets
