What you will do:

• Test features against requirements — analyze acceptance criteria, design flexible and resilient test scenarios using test design techniques to maximize coverage and minimize risks.

• Document and prioritize defects — create reproducible steps, attach screenshots/logs, and provide clear descriptions to speed up bug fixing.

• Maintain test documentation — checklists, regression notes. Keep documentation up-to-date and scalable as the product grows.

• Prepare Release Candidates for production
  – Validate build stability
  – Work with configuration files (JSON): verify flags, values, and conditions affecting production functionality

• Set up and validate A/B tests — help define conditions and ensure experiments run correctly for target user segments.

• Take ownership of quality — understand how testing impacts product, users, and business. Be able to defend quality decisions and take initiative in edge cases.

• Participate in cross-team activities — planning, retros, discussions. Maintain product quality through collaboration with development, analytics, design, and marketing.

Key qualifications:

• 2+ years of QA experience, preferably in mobile or cross-platform products. Ability to work with requirements, independently design test scenarios, and assess risks.

• Strong understanding of mobile platforms (iOS & Android): architecture basics, UI/UX patterns, background behavior, permissions, and app lifecycle.

• Ability to select test devices — justify device/OS selection based on target audience, market, and product specifics.

• Understanding of iOS Sandbox and Google Wallet — limitations, security policies, and testing specifics for payments and authorization flows.

• Experience with mobile testing and debugging tools:
  – Charles Proxy (traffic interception & analysis)
