  • Advocate for the user experience by identifying and escalating UX inconsistencies, friction points, or confusing AI behaviours.

  • Execute test cases, analyse results, and clearly report bugs and errors.
  • Collaborate closely with cross-functional teams including engineers, QA, product, design to ensure quality is embedded throughout the development lifecycle.

  • Familiarity with writing and reviewing acceptance criteria (e.g. Gherkin or similar syntax).
  • A sharp eye for UI/UX quality and a passion for advocating for end users.
  • Experience using tools like Jira, Notion, or TestRail to manage test cases and report bugs.
  • Comfortable working in Agile/Scrum teams, collaborating with engineers, product managers, and designers.
  • Excellent communication and attention to detail - you’re curious, proactive, and thorough.
  • Ability to work independently, manage priorities, and take initiative in a fast-moving environment.
