Mid-Senior QAE Mobile - Remote Portugal

ABOUT THE OPPORTUNITY

Join a leading technology company as a Senior Quality Assurance Engineer specializing in mobile testing across Android and iOS platforms. You'll work for a software engineering company that builds products they're proud of with people they love, where the whole team owns projects together in a politics-free environment. The culture reflects lean, self-organization that encourages risk-taking, collaborative decision-making, and enhanced communication across all levels.

Your primary focus will be developing and executing comprehensive test strategies combining both manual and automated approaches to identify and resolve defects while working closely with development and product teams. You'll create and maintain automated mobile UI tests using Maestro, work with Android Studio and Xcode, analyze network traffic with Charles Proxy, and contribute to automation strategy and CI/CD pipeline maintenance. This mid to senior-level position requires 5+ years of QA experience with mandatory expertise in Maestro, Android Studio, Xcode, Charles Proxy, YAML, and JavaScript, plus advanced English (C1 level).

PROJECT & CONTEXT

You'll ensure quality for mobile applications in the retail sector, working across Android and iOS platforms to deliver exceptional mobile experiences. Your role centers on developing and executing test strategies combining manual testing expertise with automated frameworks, identifying defects early, and collaborating with development teams to maintain high-quality standards throughout the software delivery lifecycle.

Maestro is your primary tool for mobile UI automation - you'll create, maintain, and execute automated tests using Maestro framework, write test scenarios in YAML format, and ensure comprehensive coverage across user flows and UI interactions. Your Maestro expertise enables efficient, maintainable automation that catches regressions and validates functionality across both platforms.

Working with Android Studio and Xcode is essential - you'll use Android Studio for building, running, and debugging Android applications during testing, use Xcode for iOS testing and device simulation, analyze logs and crash reports from both platforms, and understand app behavior at a technical level enabling effective bug identification and reproduction.

Charles Proxy is critical for network analysis - you'll intercept and validate network traffic to verify API calls, inspect request/response payloads, identify network-related issues, validate data integrity, and debug backend integration problems. Understanding how mobile apps communicate with servers enables you to catch issues invisible through UI testing alone.

JavaScript proficiency supports your automation efforts - you'll write auxiliary scripts for test integration, create helper functions enhancing test capabilities, integrate with CI/CD pipelines, and handle test data preparation. Your JavaScript skills complement YAML-based Maestro tests and enable sophisticated automation scenarios.

Collaboration defines your daily work - you'll work closely with developers to reproduce and resolve issues, participate in quality decisions and suggest process improvements, contribute to automation strategy discussions, and communicate findings clearly in agile ceremonies. You'll investigate and report bugs systematically by analyzing logs, examining crash reports, documenting reproduction steps clearly, and validating fixes thoroughly. You'll critically evaluate existing testing scripts and frameworks to identify improvement areas, propose new approaches when appropriate, and drive continuous improvement in testing efficiency.
