  • 4+ years of experience remediating digital accessibility issues in websites, apps, and platforms
  • Strong coding experience in HTML, CSS, JavaScript, and ARIA markup
  • Working knowledge of Sitecore and Salesforce platforms, with demonstrated remediation success
  • Familiarity with Biznet applications, AWS infrastructure, or common enterprise back-end platforms
  • Ability to interpret automated and manual testing results (e.g., Axe, ANDI, NVDA, JAWS) and apply solutions
  • Expert knowledge of WCAG 2.1 AA standards and assistive technology interactions
  • Proficiency in CMS templates, JavaScript frameworks, backend API configuration, and UI component libraries
  • Experience troubleshooting keyboard traps, focus management, form label/field logic, and responsive layouts
  • Strong ability to work in agile sprints, manage remediation tickets, and track progress in Jira or similar tools
  • Ability to collaborate with QA testers, content editors, and project managers in an agile environment
  • Excellent communication and documentation skills for communicating fixes and coaching teams

Preferred Skills & Qualifications

  • Experience with Sitecore MVC or SXA customization
  • Front-end developer or CMS certifications
  • Accessibility remediation tools
  • Experience with customized CMS themes, templates, and components
  • Strong attention to content structure (heading levels, alt text, semantic HTML)
  • Experience remediating PDF, Word, or PowerPoint documents (for secondary support)
  • Familiarity with CI/CD integration of accessibility checks (i.e., axe-core in pipelines)
  • Familiarity with design handoff tools (i.e., Figma or Adobe XD) for accessibility review

  • Deque University Developer Track Certificate
