• Proven experience in both QA (process improvement, prevention) and QC (testing, detection).
• Strong skills in executing manual testing across various platforms and environments.
• Experience in test case creation, maintenance, and execution.
• Ability to define, track, and report on key test metrics to measure quality and progress. Experience supporting continuous integration and delivery processes, ensuring quality checkpoints are met at every stage.
• Excellent experience in implementing and maintaining test-automation systems for different scopes (unit-, integration-, reliability-, upgrade-, load-, frontend-testing) as part of a software development pipeline.
• Profound knowledge of test automation frameworks and software quality checkers for different programming languages.
• Experience in managing external testing campaigns.
• Experience in mentoring and training less experienced QA engineers and software developers.
• Broad range of experience including the following Git, integration of software lifecycle tools like ticketing system and Jira/Confluence etc., building of CI/CD pipelines and further automation related technology.
