About the Role We are looking for a Senior UX Designer to join a cross-functional team responsible for Helix, our design system, and the user experience across three SaaS products: Amino, Sonar, and Proline.
This role covers the full range of UX practice.
You will take on product design work alongside the team and bring a specialized focus on AI/UX, defining how our products communicate and behave when artificial intelligence is involved.

and explainability surfaces - Partner with product and engineering teams integrating AI features to establish UX guardrails and reusable patterns - Review AI-driven features across products and identify where the experience breaks down or erodes user trust - Track emerging AI UX research and translate relevant findings into practical patterns for the team What We're Looking For Required - 5+ years of UX design experience with a strong generalist foundation; you can own a feature end to end - Demonstrated work on products that include AI or ML components - Solid grasp of human-AI interaction principles: communicating model behavior, failure modes, and uncertainty to non-technical users - Experience designing for error states, edge cases, and degraded-mode experiences in systems with AI - Experience designing within or contributing to a design system - Proficiency in Figma - Strong written and verbal communication in English Preferred - Familiarity with AI/ML concepts at a product level; enough to have a substantive conversation with a data scientist or ML engineer - Experience with conversational UI, co-pilot patterns, or AI-assisted workflows - Exposure to explainable AI principles and how they surface in product design #J-*****-Ljbffr
