Reporting to a senior member of the QA team, the QA Engineer will be primarily responsible for accessibility testing across Calastone’s client-facing web applications, ensuring compliance with WCAG 2.1/2.2 (Level AA) standards and delivering an inclusive user experience. The role combines automated accessibility testing using Playwright with Axe integration, and manual accessibility evaluation using WAVE and Axe Chrome browser extensions. As a secondary focus, the role provides a pathway into broader UI test automation using Playwright - a highly transferable skill that strengthens both the individual’s career and the team’s overall automation capability. The QA team uses AI-augmented workflows (Claude Code, MCP integrations) to accelerate test design, execution, and defect analysis. You will be expected to adopt these tools as part of your day-to-day work.

Candidates developing automation skills: be introduced to the team's existing suite and supported in building Playwright capability on the job. Over time, contribute to broader UI test automation including functional and cross-browser testing.
