🚀 About Omnilex

Omnilex is a young dynamic AI legal tech startup with its roots at ETH Zurich. Our passionate interdisciplinary team of 10+ people is dedicated to empowering legal professionals in law firms and legal teams by leveraging AI for legal research and answering complex legal questions.

• Raise visual and interaction quality across the product; add motion/micro-interactions where they genuinely help
• Prototype and validate new interaction patterns; run lightweight usability checks with users and the team
• Drive performance (SSR/streaming, routing, caching, lazy loading) and reliability (error states, offline/optimistic UX)
• Establish frontend quality practices: meaningful tests (unit/E2E), code reviews, and maintainable architecture
• Instrument analytics and feedback loops to reveal confusion points and measure adoption
• Collaborate closely with product, AI, and legal experts; turn ambiguous workflows into clear, guided experiences
• Mentor engineers; set standards that scale as the team grows
