Working alongside our PdM and frontend devs, you'll own UI/UX design for our SaaS product. It's early-stage but past product-market fit, with real users. This isn't website design. It's product design for a SaaS application used daily in real workflows. You won't write production code, but you'll work closely with the devs. This is a mid-to-senior role. We expect you to take a loosely defined problem to a shipped answer, including interviewing customers and operators yourself. Our product is in security. A security background isn't required, but a willingness to learn the domain is. You can't design operator workflows well without understanding the work. # Language Requirements Our dev team works in both English and Japanese. Japanese is required, since our customers and internal security operators are Japanese speakers. # What We Look For - Clean, well-crafted UI with clear reasoning behind it - Improving UX autonomously through direct conversation with users and internal operators - Designing reusable components and patterns that stay coherent as the product grows - Handing off cleanly to engineers, including states and edge cases, and following through to release - Willingness to learn an unfamiliar domain in depth # Requirements - A portfolio. We'd like to see how you think, not only final screens: the problem, what you tried, what you'd change now. Any format works. - Japanese communication skills sufficient to interview customers - Proficiency with Figma. We design in Figma and Claude Design. # Nice to Have - Ability to move faster with AI tools while owning the final output (no AI slop) - Ability to communicate in English - Existing knowledge of the security domain - Experience designing internal tools or operator-facing workflows # Working Environment - A foreigner-friendly workplace with many international team members - Fully remote - Flextime, core hours 10:00–14:00 - Laptop and monitor provided - Claude and other AI tools available
