Middle Manual QA (Mobile)

We're looking for a Manual QA to join our Esti team and take full ownership of testing one of our mobile applications. You’ll be part of a small, cross-functional product team, ensuring the app runs smoothly and meets quality standards. Esti (https://esti.app/) is a leading aesthetic photo editing app on a mission to become the #1 player in the market.

We have plenty of documentation, structured onboarding process and a mentor to support you. That said, we’re looking for someone proactive – someone who first tries to figure things out independently before turning to the team.

One key thing to keep in mind: our products are young and evolving fast. Development cycles are quick, with at least one release per week. If you thrive in a fast-paced environment and can stay cool under pressure, you’ll fit right in!

• Analyzing PRDs, designs, and requirement gaps, and leading features all the way to release readiness;
• Evaluating user, technical, and business risks to select the optimal testing depth based on timelines;
• Performing all types of testing (feature, integration, exploratory, regression) for the mobile app, including API, analytics, A/B tests, paid flows, and GenAI;
• Logging reproducible bugs with clear user impact, providing developers with full context, conducting prompt retests, and driving defects to resolution;
• Conducting test analysis, maintaining the mobile regression model, creating test cases and checklists, and preparing scenarios for automation;
• Effectively leveraging LLMs for requirements analysis and test design while maintaining personal accountability for the output;
• Communicating with cross-functional teams and participating in user feedback and incident triaging;

• Identifying QA process inefficiencies and implementing systemic changes that prevent entire classes of issues rather than just adding single test cases.
