🌟 About You

Do you turn complexity into clarity? Are you excited to run real user research, map journeys, craft wireframes, and validate designs - then ship changes that immediately reduce confusion? Do you bring a strong, evidence-based point of view, can align stakeholders, and say “no” to protect focus when needed? If so, we’d love to hear from you.

🚀 About Omnilex

Tasks

🛠️ Your Responsibilities

As a UX/UI Designer - AI Product, you’ll establish a research-led UX practice and turn our expanding feature set into a coherent, intuitive product.

• Research & insight: plan and run interviews/usability tests; synthesize findings into personas, journey maps, and task flows.
• IA & navigation: clarify mental models and information architecture; resolve recurring confusion (e.g., when to use which view/flow).
• Wireframes & prototypes: produce low→high fidelity artifacts; validate quickly with users; iterate based on evidence, not opinions.
• Design system & states: define patterns, empty/loading/error states, and AI-specific states (thinking, confidence, retry/undo).
• Specs & handover: write clear specs with acceptance criteria; partner tightly with engineering; own design QA through to what ships.
• Measure & learn: instrument UX metrics (e.g., confusion behaviors, drop-offs); use PostHog/analytics to verify improvements.
• Alignment & cadence: lead design reviews, keep stakeholders aligned, and maintain a lightweight but consistent UX process.
• Focus & prioritization: sequence work for maximum user impact; protect focus and negotiate scope when requests conflict.

In your first months you will: baseline the top UX confusion points, redesign the IA/navigation where needed, validate the top three workflows with users, and ship fixes with measurable impact.

Requirements

✅ Minimum qualifications

• Strong portfolio showing end-to-end UX work: research → IA/journeys → wireframes/prototypes → shipped UI and measurable outcomes.
• Fluency with Figma (components, auto-layout, prototyping) and modern UX methods (usability testing, heuristic reviews, synthesis).
• Evidence-based product sense: you can argue clearly for decisions using user data and trade-offs.
• Experience collaborating closely with engineers; you follow through to what ships and hold a high quality bar.
• Proficiency in English.
• Availability full-time. On-site in Zurich at least two days per week (hybrid).

🎯 Preferred qualifications

• You have a Swiss work permit or EU/EFTA citizenship.
• Working proficiency in German (user interviews and usability testing).
• Experience with analytics tools (e.g., PostHog) and defining UX success metrics.
• Background designing complex B2B workflows or AI-assisted products.
• Optional: Comfort reading or implementing UI code for critical flows (React/TypeScript/Tailwind) or pairing closely to ensure faithful implementation.

Benefits

🤝 Benefits

• Direct impact: your research and designs will immediately reduce confusion and boost adoption and user trust.
