About Mercari
Circulate all forms of value to unleash the potential in all people
"What can I do to help society thrive with the finite resources we have?" The Mercari marketplace app was born in 2013 out of this thought by our founder Shintaro Yamada as he traveled the world. We believe that by circulating all forms of value, not just physical things and money, we can create opportunities for anyone to realize their dreams and contribute to society and the people around them. Mercari aims to use technology to connect people all over the world and create a world where anyone can unleash their potential. For more information about Mercari Groupâs mission, see Mercariâs Culture Doc
ã
Organization/Team Mission
In the Marketplace Design Team, we lead end-to-end user experience design for buyers in Japan by shaping intuitive, trustworthy, and high-quality shopping experiences. We partner closely with Product, Engineering, and Research to explore new problem spaces, define experience direction, and raise the bar for craft, consistency, and innovation across the marketplace.
See here for more information about our mission and values.
ã
Why this role matters
This role plays a critical part in shaping how buyers experience Mercari at scale. As the marketplace evolves, weâre entering new problem spaces where clarity, trust, and experience quality matter more than ever. Senior Designers in this role donât just execute solutions â they help define the problems worth solving and set the bar for what âgoodâ looks like.
Youâll be trusted to operate with a high degree of ownership, leading end-to-end experiences in ambiguous areas while balancing user needs, business goals, and long-term product quality. Your work will directly influence how buyers discover value, make confident decisions, and build trust with the marketplace.
This role matters because strong design leadership here creates leverage: it unlocks better collaboration, sharper product thinking, and more durable experiences that scale beyond a single feature or release. Weâre looking for designers who care deeply about craft, can think beyond the immediate task, and want to shape the future of the buyer experience in Japan.
ã
Work Responsibilities
- Own the end-to-end design for buyer-facing experiences, from discovery and problem framing through execution and launch.
- Act as Lead Designer for assigned product areas, setting experience direction and design quality standards.
- Translate ambiguous business and user problems into clear experience strategies, flows, and high-quality UI.
- Drive design decisions through strong craft, systems thinking, and user-centered rationale.
- Collaborate deeply with PM, Eng, and UXR to shape product direction and influence roadmaps.
- Identify gaps and opportunities beyond the immediate scope and proactively propose new ideas, concepts, or improvements.
- Contribute to and evolve shared design systems, patterns, and best practices.
- Provide thoughtful feedback and mentorship to other designers, raising the overall quality of work.
ã
Unique Challenges
- Designing for large-scale, real-world marketplace complexity with diverse buyer needs and behaviors.
- Leading design in unexplored or undisclosed product areas with high ambiguity and few precedents.
- Balancing speed, experimentation, and innovation with a high bar for craft, trust, and usability.
- Navigating cross-team and cross-function alignment while maintaining clear experience ownership.
- Designing for the Japanese market with strong attention to cultural nuance, trust, and clarity.
ã
Qualifications
- Required Experience/Skills
- 6+ years of experience in product, UX, or interaction design with ownership of end-to-end experiences.
- Strong craft skills across UX, interaction design, and visual design, with a sharp eye for detail and quality.
- Proven ability to lead design for complex or ambiguous problem spaces.
- Experience influencing product direction through design thinking, concepts, and storytelling.
- Solid understanding of design systems, scalable patterns, and consistency at scale.
- Strong collaboration and communication skills with cross-functional partners.
- A portfolio demonstrating high-quality shipped work, problem-solving depth, and design leadership.
- Preferred Experience/Skills
- Experience designing marketplace, e-commerce, or transaction-based products.
- Experience acting as a lead designer across multiple teams or initiatives.
- Familiarity with user research methods and applying insights to design decisions.
- Experience working in or designing for the Japanese market.
