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.
