• Drive mobile testing best practices, including testing on real devices and emulators, parallel execution, and handling OS-specific behaviours.
• Advocate for quality across the development lifecycle by participating in code reviews, sprint planning, and release planning.
• Troubleshoot and isolate complex issues, providing detailed documentation and feedback to development teams.
• Mentor and guide junior QA engineers in test automation strategy and implementation.

Required skills and Experience:

• Professional level (6+ years’ experience) as an Automation QA with at least 4 years focused on Android mobile apps.
