Senior Accessibility Engineer

Job Purpose Unily is committed to delivering an accessible platform that meets best-in-class standards and follows accessibility best practices, with our priority being to ensure the product is usable and not just compliant. This role spans methodical conformance work across our established platform alongside greenfield work where accessibility can be built into the design system and component library from day one. It sits in the UI Team within the Design organisation, working closely with Product Designers, the Design System team, and UI Developers, and partnering directly with the Digital Accessibility Manager on Unily’s accessibility roadmap and governance. Main Responsibilities Work within the UI Team alongside Product Designers, the Design System team, and UI Developers to deliver accessible UI across both established and greenfield product surfaces. Partner with the Digital Accessibility Manager to deliver Unily’s accessibility roadmap, governance model, and WCAG 2.2 AA conformance targets. Contribute directly to the design system accessibility goal of ≥90% AA conformance for design system components. Build accessibility into greenfield work from the outset, working with designers to shape accessible patterns at design time before they harden. Lead methodical remediation of known accessibility gaps in the established platform, prioritising fixes by user impact and ensuring key journeys are usable with keyboard and assistive technologies. Apply deep knowledge of WCAG 2.1 and 2.2 success criteria to interpret standards and translate them into usable interaction patterns in HTML, ARIA, and CSS (e.g., clear focus, predictable navigation, and understandable names and instructions). Help set and uphold the accessibility quality bar for the design system, core product surfaces, and the mobile app, partnering with design, engineering, and QA to drive consistent standards. Work with QA Engineers to ensure accessibility testing validates real usability, combining automated checks in CI/CD with task-based manual testing across assistive technologies, input methods, and browsers. Explore and evaluate emerging AI-assisted tooling across accessibility analysis, design, and implementation, piloting where it adds value to surface issues earlier and streamline remediation. Drive adoption of accessible patterns across feature teams through code review, pairing, and internal training, helping teams build accessibility into their day-to-day development. Identify and implement enhancements to the accessibility process to ensure continuous improvement.
