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.

What You'll Be Responsible For

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 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

- Experience in SaaS or enterprise software environments

- Understanding of how design tokens and component APIs support scalable pattern libraries

Differentiators

- Portfolio work that specifically addresses trust, uncertainty, or error communication in AI products

- Evidence of influence on how a product team adopted AI UX standards or patterns, not just individual screen execution

- Familiarity with established AI UX guidelines from Nielsen Norman, Google PAIR, Microsoft HAX Toolkit, or similar sources

Skills

- Critical thinking skills, with the ability to challenge assumptions and evaluate trade-offs across user needs, business goals, and technical constraints

- Deep empathy for users, with the ability to understand their context, constraints, frustrations, and goals before jumping into solutions
