QA Engineer

Job Qualification:

• Minimum 3 years of professional QA experience in web applications.
• Strong manual testing fundamentals, including test case design, test plan structure, and regression suite maintenance.
• Demonstrated ability to identify edge cases through structured analysis rather than ad hoc clicking.
• Familiarity with Playwright, or demonstrated willingness and capacity to learn it, supported by prior exposure to any automation framework or scripting language.
• Comfortable with browser developer tools, network inspection, and reading application logs.
• Working knowledge of API testing tools such as Postman.
• Basic JavaScript/TypeScript, SQL and Python literacy sufficient to write and modify test scripts.
• Experience testing responsive web applications across browsers and devices.
• Experience with data integrity testing.
• Proficiency in bug tracking and test management tools (e.g., Jira, Notion).

Job Description:

• Design test cases that cover scientific and laboratory requirements, including sample handling logic, result validation rules, measurement thresholds, and domain specific edge cases where incorrect output carries consequences beyond user inconvenience.
• Execute manual testing across commercial facing products as the primary priority, and internal dashboards as the secondary priority.
• Conduct functional testing of complex business logic and domain-specific features. Own regression testing cycles, maintaining and executing regression checklists ahead of each release to confirm existing functionality remains intact.
• Perform exploratory testing to surface edge cases and defects not captured by scripted test cases.
• Document defects with clear reproduction steps, environment details, and expected versus actual behaviour, and follow through with developers until resolution.
• Maintain the test case library and regression documentation as a shared team asset.
• Assist with stress testing to identify performance bottlenecks.
• Develop test automation capability using Playwright, progressing from scripting individual regression cases toward a maintained suite suitable for future CI/CD integration.
• Collaborate with the VP of Digital Product, Engineering Lead, and developers during sprint planning and refinement to clarify acceptance criteria before development begins.
