• Owning end-to-end testing of complex back-end and cloud services running on AWS, Docker, and (where needed) VM setups • Designing, writing, and adapting automation scripts for API and environment testing across both SaaS and on-premises deployments • Validating integrations between CKEditor Cloud Services and depending components like CKEditor 5, Customer Portal • Running performance, stress, and regression testing on CKEditor ecosystem services • Partnering with developers to reproduce, triage, and resolve customers' technical and integration issues • Proactively identifying quality risks in the system and proposing improvements to test coverage, tooling, and CI reliability

• Define the scope and acceptance criteria for tests based on system requirements. • Develop test plans and strategies to ensure adequate coverage. • Identify risks and potential impacts related to software failures. • Specify test cases based on requirements and business rules. • Create test scripts for functional, regression, integration, usability, load, and security testing. • Execute manual and/or automated tests. • Identify, document, and report defects. • Validate bug fixes and perform regression testing. • Develop and maintain test automation scripts (when applicable). • Record and document test results. • Recommend improvements based on test analysis. • Collaborate with developers, requirements analysts, and software architects. • Participate in refinement sessions and requirements-definition meetings. • Ensure software quality best practices are followed.

• Automated Testing: Design, develop, and execute automated test scripts for software using industry-standard tools and frameworks (e.g., Selenium, TestNG, Junit, JMeter, Phyton). • Test Strategy: Implement automated testing strategies and frameworks to enhance testing efficiency and coverage. • Integration: Collaborate with development teams and integrate automated tests into the CI/CD pipeline. Document progress and issues in Jira and communicate via Microsoft Teams. • Performance Testing: Conduct performance and load testing to assess system scalability and robustness. • Troubleshooting: Identify, analyze, and troubleshoot complex issues in both automated and manual testing environments. • Documentation: Maintain detailed documentation of test cases, test scripts, and testing processes in Jira. Use Excel for analyzing and reporting on testing metrics, applying advanced functions as needed. • Data Analysis: Utilize SQL Server Management Studio for validating backend data and understanding data relationships to ensure accuracy. • Time Management: Demonstrate effective time management to handle multiple priorities and deliver high-quality results on time.

• Serve as the primary QA point of contact for your assigned area of the platform, owning test coverage across a broad and technically complex surface area. • Participate in sprint planning and ticket grooming to ensure upcoming work is testable, well-scoped, and meets quality standards before development begins. • Conduct functional, regression, and exploratory testing for new features and bug fixes across assigned functional areas. • Identify, document, and track bugs in Shortcut with clear reproduction steps and supporting context. • Work closely with developers to ensure timely bug resolution and clear communication of issue severity and scope. • Lead QA-side root cause analysis (RCA) for bugs that reach production by reproducing issues, identifying testing gaps, and implementing process or test improvements to prevent recurrence. • Test from the perspective of the end user to identify usability issues and provide thoughtful feedback to the product team aimed at improving the overall customer experience. • Plan, create, and maintain automated test coverage for your assigned area in collaboration with the QA Automation Architect. • Identify high-value test cases for automation and prioritize coverage that reduces manual regression burden over time. • Review and contribute to the shared automation framework, ensuring your tests follow established patterns and best practices. • Maintain existing automated test scripts as features evolve, keeping coverage accurate and reliable. • Collaborate with the QA Automation Architect to expand automated coverage and integrate tests into CI/CD pipelines. • Provide feedback on automation strategies, tooling, and testing practices to continuously improve QA processes. • Step in flexibly across squads or testing efforts as business needs shift. • Operate with a high level of autonomy — navigate ambiguity, make informed decisions, and maintain momentum without constant direction.
