Senior QA Automation Engineer

Role:

Senior QA Automation Engineer

About You:

Are you the kind of engineer who sees quality as a technical challenge rather than a manual process? Do you enjoy building automated test frameworks, creating release safeguards and preventing production issues before they happen? Are you as comfortable writing code as you are designing quality strategies and identifying risks across complex systems? If you enjoy improving how software is built, tested and released, DFYNE could be exactly where you belong.
