Job description

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 specialised 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, colour 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 colour 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 organisation 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.
