Stack: HTML and CSS (required), React and TypeScript (a strong advantage), design systems, AI tools such as Claude, ChatGPT, Cursor and more  Experience: You have designed and prototyped complex B2B SaaS or enterprise applications, typically with about [YEARS | 3]+ years in UX, product design or frontend roles. English: C1 or higher Contract: Full-time, indefinite B2B contract with Radity; you invoice Radity monthly in USD. Location: Remote  Core hours: [09:00–18:00 CET], with evening overlap with US clients The company Radity is a Swiss-based software engineering company of 70+ people, fully remote and working mostly with US clients, many in insurance. It is founder-managed, with direct access to the CEO. Its teams build business applications with data-heavy interfaces, forms and workflows. Radity is adding AI-native design and frontend prototyping next to its UX designers, so ideas reach a prototype people can test in short cycles. You join a team with 2 Design Engineers and report to the CEO. This is not a pure UX design or marketing web role: you design the solution and build the prototype. What you'll do Turn business requirements into clear user flows and product concepts. Design forms, workflows, dashboards and tables for data-heavy B2B applications. Build functional prototypes, from plain markup to working frontend components. Simplify complex processes and improve existing user journeys. Use and extend existing design systems. Iterate in short cycles on feedback and real product constraints. Work directly with product, engineering and business stakeholders. What you bring Strong UX and product design: usability, interaction design and information architecture. A portfolio of real application design, not mainly marketing websites. Fast iteration: from requirement to prototype, feedback and a better version. Reusable components and design-system thinking. Comfort with incomplete or changing requirements, and the judgment to simplify. AI tools as a normal part of your research, design and prototyping work. Clear communication with product, engineering and business stakeholders. Nice to have: finance, insurance or another complex business domain. Not for you if you prefer a long, fully specified design process, or do not want to build prototypes yourself. What Radity offers Indefinite contract: not tied to the end date of one project. Full equipment, paid AI tools and learning budget. Global team events. Startup-style projects for established clients, with real influence on direction. Performance and salary reviews twice a year. Hiring process About 2–3 weeks in total, with no take-home task. After each step, you hear from us within 2 business days, with feedback. Intro call with Radity HR CEO interview Offer.
