(Senior) Quality Assurance Engineer (f/m/d)

• Shape and continuously improve the quality engineering strategy for the Backoffice application
• Design and build automated test infrastructure across unit, integration, API and end-to-end levels with a strong focus on Playwright and TypeScript
• Develop reusable test fixtures, test-data seeding, environment tooling, harnesses and abstractions that make realistic and repeatable testing easy.
• Build fast automated feedback loops and validation mechanisms that make AI-assisted development safer and more effective.
• Design meaningful regression coverage for critical workflows, complex permissions and scenarios with financial, operational or compliance impact
• Strengthen CI quality gates and improve test execution so that a green pipeline provides a strong and fast signal that changes are safe to ship.
• Investigate defects, flaky tests and systemic quality issues and turn findings into durable engineering improvements.
• Triage bug reports together with internal users, reproduce issues and turn findings into clear actions for the team.
• Champion a strong quality mindset across the team and challenge workflows and designs from an end-user perspective to identify usability issues and edge cases early.
• Foster knowledge sharing and collaboration with the wider QA community at ZEAL to exchange practices, tools and learnings.
• Work closely with engineers, Product, UX and backend teams to identify risks early, improve testability and build quality into the development process

What you offer us:

• Strong software engineering skills and experience in quality engineering, test automation, SDET or a comparable engineering-focused role.
• Strong hands-on experience with TypeScript or JavaScript and the ability to contribute production-quality code directly to a modern web application.
• Experience designing and building test frameworks, tooling, harnesses, fixtures and automation infrastructure rather than only writing individual test cases
• Strong experience with Playwright, Cypress or a similar modern end-to-end testing framework.
• Good understanding of APIs, distributed systems, CI/CD pipelines and applications that integrate with multiple backend services
