THE ROLE

We are seeking a skilled and detail-oriented Mobile QA Automation Engineer with a strong background in the Android ecosystem.

If you have experience with SDKs and a passion for data-driven development, we want to hear from you.

• Automation Development: Experience in building and maintaining automation scripts/frameworks.
• Analytics & Backend Platforms: Hands-on experience working with Firebase or similar analytics platforms.
