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.

AI/UX is your area of depth, not your only responsibility.

Product Design
- Own UX design work across Amino, Sonar, and Proline: flows, wireframes, interaction specs, and design reviews
- Collaborate with product managers and engineers to define and validate interaction decisions
- Participate in design critiques and contribute to design quality across the team
- Plan and support usability testing, prototype validation, and design feedback sessions to identify friction, validate assumptions, and improve product decisions

AI/UX
- Design interaction patterns for human-AI workflows: trust signals,



confidence indicators, uncertainty communication, and progressive disclosure of AI reasoning
- Extend Helix with AI-specific components covering processing states, error handling, feedback loops, 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
