• Provide a complete and detailed analysis of failing tests to help engineering teams better understand the corrective actions to implement.
• Assess risk from test results and alert potential issues in time.
• Deliver thorough, well-structured reports to facilitate clear communication with diverse stakeholders.
• Engage the squad team in agile testing methodology and E2E testing, share knowledge, and be able to create debate on current practices.

• Engineering degree is a plus.
• Desktop application testing and experience with hardware-connected products are a plus.
