Your mission

• Drive quality of our mobile apps (iOS & Android) through the whole SDLC.
• Elaborate, maintain and implement detailed test plans and test cases for mobile features; help define acceptance criteria for different scenarios.
• Perform manual functional, regression, and E2E testing on real iOS and Android devices as part of frequent release cycles.
• Apply extensive exploratory testing to identify possible risks, including edge cases specific to mobile (OS versions, device types, permissions, connectivity, interaction with hardware devices).
• 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.

• Good knowledge of development processes and agile methodology.
• Autonomous and proactive: able to work as the main QA within a squad and drive quality without close supervision.
• Team work spirit, great organizational and communication skills.
• Able to challenge decisions when necessary.
• Fluent English is mandatory.
• Engineering degree is a plus.
• Desktop application testing and experience with hardware-connected products are a plus.
