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 accessibility, ensuring that Helix components are designed to be accessible from the start and that existing product surfaces meet a real accessibility standard.

Accessibility 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

Accessibility

Design Helix components with accessibility built in: focus management, color contrast, keyboard navigation, screen reader semantics, and motion sensitivity

Conduct accessibility audits on existing product surfaces and deliver actionable remediation roadmaps

Define and maintain accessibility guidelines within design system documentation

Partner with UX developers and frontend engineers to verify that implementation matches accessible design intent

Educate and advocate across the team for accessible design practices

What We’re Looking For
Required





4+ years of UX design experience with a strong generalist foundation; you can own a feature end to end

Deep working knowledge of WCAG 2.1/2.2 at AA and AAA levels

Experience designing within or contributing to a design system

Familiarity with assistive technologies from a design validation perspective: screen readers, keyboard navigation, voice control

Ability to conduct structured accessibility audits and communicate findings to both design and engineering audiences

Proficiency in Figma

Strong written and verbal communication in English

Preferred

Familiarity with ARIA patterns and how they shape design decisions

Experience with accessibility testing tools such as Axe, Lighthouse, NVDA, or VoiceOver

Understanding of how Angular or component-based frameworks implement accessible UI

Experience in SaaS or enterprise software environments

Exposure to color systems and design token structures

Differentiators

Formal accessibility certification, such as CPACC, WAS, or equivalent, will be weighted in the evaluation process

Experience establishing accessibility standards at the organization level, not just within individual projects

Track record of auditing and remediating existing products, not only designing greenfield experiences

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

Comfort navigating ambiguity.
