UX/UI Design Intern

Do you turn complexity into clarity? Do you want to run real user interviews in German with claims experts, turn them into flows and wireframes, and show your ideas as a working prototype in the same week? Do you treat AI tools not as a gimmick but as a natural part of your craft? Then we would like to meet you.

iudexnc (Iudex Non Calculat) is an early-stage AI startup based in Zurich. We build the infrastructure that automates the coverage check for legal protection insurers. Every case is still reviewed manually in 15 to 45 minutes today. We bring that to under 2 minutes.

As a UX/UI Design Intern you own the user experience of our two product surfaces: the coverage check (assessing a case along temporal, subject-matter, territorial and personal coverage as well as exclusions) and the AVB Studio (creating, versioning and commenting on policy conditions).

• User research in German and English: Plan, moderate and analyse interviews and usability tests with claims experts, handlers, product managers and underwriters. Condense the findings into personas, journeys and task flows.
• Information architecture: Clarify our users' mental models and build navigation and structure so that nobody has to guess which view is for what.
• Wireframes and prototypes: Go from low to high fidelity in short cycles, validate quickly with real users, and iterate on evidence rather than opinions.
• Rapid prototyping with AI tools: Instead of click dummies, you build running prototypes (for example with v0, Lovable, Figma Make, Cursor or Claude Code) that we can put straight in front of users.
• Design system and states: Define patterns, components and states, including empty, loading and error states as well as AI-specific states (uncertainty, source citations, correcting and undoing).
• Specs and handover: Write clear specifications with acceptance criteria, work closely with engineering, and see design QA through to release.
• Measure and learn: Define UX metrics and use analytics (for example PostHog) to check whether your changes actually work.

In your first weeks: you speak with real users at an insurer, document the biggest comprehension problems in the coverage check and AVB Studio, and deliver a first redesign proposal as a working prototype.

✅ Minimum qualifications

• German at native or business-fluent level (C1 minimum). All user interviews and usability tests take place in German, in part with Swiss German speakers. Good English as the team language on top.
• AI tools are part of your craft: You work with LLMs and AI-assisted design and prototyping tools daily, and can show how that makes your output concretely faster and better.
• Portfolio with end-to-end work: Research, information architecture, wireframes and prototypes through to shipped interfaces.
• Confident with Figma (components, auto layout, prototyping) and with common UX methods (usability tests, heuristic reviews, synthesis).
• Evidence-based product thinking: You justify design decisions with user data and name the trade-offs.
• Ongoing or recently completed studies in interaction design, HCI, design, computer science or comparable, or equivalent practical experience.
• Availability 60 to 100%, ideally for 6 months. At least two days per week on site in Zurich (hybrid).
• Swiss work permit or EU/EFTA citizenship.

🎯 Nice to have

• Engineering skills are a big plus: If you can build your designs as fully functional prototypes yourself (React, TypeScript, Tailwind), that is a strong argument for us.
• Experience with complex B2B workflows or AI-assisted products.
• Interest in insurance, law or legal tech, or an appetite for getting up to speed in a specialist domain quickly.
• Experience with analytics tools (for example PostHog) and with defining UX success metrics.
• French language skills for our expansion into Romandy and France.

• Direct impact: Your decisions land in the product and with users within days, not in a drawer.
• Ownership: You help build our UX practice from the ground up, including the design system and research process.
• Close to users: Weekly contact with claims experts and insurers, rather than design at second hand.
• Team: A small, interdisciplinary team from engineering, legal and business. Flat hierarchies, written decisions, few meetings.
• Compensation: CHF 2,000 to 3,000 per month at 100%, pro rata at a lower workload, depending on experience and skills.
• Perspective: The possibility of a permanent position with equity (ESOP) after a successful internship.
