Mobile QA Engineer (iOS)

About the Role
We are looking for a Mobile QA Engineer for our iOS team. You will be involved in a major redesign of our flagship trading platform, which is used by millions of users worldwide. Your work will focus on delivering an adaptive UI across different screen sizes and device families, expanding automated regression coverage, and transitioning to native Swift-based test automation. Our approach is AI-first, integrating AI tools into our daily engineering workflows, including test design, automation development, code reviews, and debugging. We work in 2-week Scrum sprints, with daily meetings at 11:00 EET/EEST.

Your role will involve owning the testing process from start to finish, including reviewing requirements, identifying potential risks, designing test cases, executing manual tests, and automating processes where appropriate. The ideal candidate has a strong product mindset, proactivity in identifying issues, collaborative spirit to work with different teams, and the dedication to drive features through testing to a successful release.

Responsibilities

• Manual Testing:

  • Perform functional, regression, smoke, end-to-end, and integration testing for new and existing iOS functionality.
  • Review specifications, identify risks and edge cases, prepare test cases and checklists, and validate the redesigned UI across different screen sizes, device families, and iOS versions.

• Test Automation:

  • Develop and maintain automated tests to expand regression coverage across product domains.
  • Contribute automated tests for new functionality including end-to-end tests and add coverage for features that are not yet covered by developer-written tests.

• Automation Migration:

  • Assist in migrating the existing test automation framework to Swift-based automation to improve maintainability, reliability, and regression coverage.

• API Testing and Debugging:

  • Test REST APIs and JSON responses, validate integrations and real-time data flows, analyze network traffic using Charles Proxy or Proxyman, and investigate issues using device logs and debugging tools.

• Cross-Platform Testing:

  • Collaborate with the Android team to verify cross-platform functionality and identify inconsistencies between iOS and Android implementations.

• CI/CD:

  • Integrate and maintain automated tests in CI/CD pipelines to ensure reliable execution and timely feedback on product changes.

• AI-Assisted Workflows:

  • Utilize AI tools in daily QA activities, including test design, test automation, code reviews, and debugging.

Requirements

• Mobile Testing Experience:

  • 3+ years of experience testing native mobile applications with a focus on iOS. Understanding of platform-specific features, guidelines, and limitations (Apple Human Interface Guidelines, Material Design).

• Test Automation:

  • Hands-on experience building and maintaining mobile automated tests using Appium, XCUITest, and/or Espresso. Ability to design a scalable test automation framework from scratch using patterns such as Page Object or Screenplay.

• Programming Skills:

  • Proficiency in at least one programming language used for test automation: Kotlin, Java, Swift, Python, or TypeScript. Ability to write clean, readable, and maintainable test code.

• Testing Theory and Test Design:

  • Solid understanding of functional, regression, smoke, integration, and end-to-end testing. Experience with test design techniques, including equivalence partitioning, boundary value analysis, decision tables, and pairwise testing. Ability to write clear test cases, checklists, and bug reports.

• API Testing:

  • Experience testing REST APIs and working with JSON. Familiarity with Postman, Swagger, and API automation tools such as REST Assured, Retrofit, or requests. Basic understanding of WebSockets and real-time data testing.

• Debugging and Traffic Analysis:

  • Experience using Charles Proxy, Proxyman, or Fiddler for traffic interception and mocking. Ability to inspect logs using Xcode Console, Android Studio Logcat, and adb.

• CI/CD and Test Infrastructure:

  • Experience integrating automated tests into CI/CD pipelines using tools such as GitLab CI, GitHub Actions, Jenkins, or Bitrise.

• AI Tools:

  • Willingness to use AI-assisted tools in everyday engineering workflows, including test design, test automation development, and debugging.

• Languages:

  • English at B1 level or above and Russian at C2 level.

Nice to Have

• Experience writing mobile automated tests in Swift using XCUITest.
• Experience migrating legacy automation frameworks or transitioning between programming languages and testing technologies.
• Experience testing financial applications, trading platforms, or other products where data accuracy and reliability are critical.

We Offer

• Full-time remote work (service provider contract).
• Competitive compensation (EUR).
• Flexible working hours.
• Corporate AI subscriptions (Claude, Gemini, GPT, etc.).
• Access to a rewards marketplace offering products and language courses, redeemable using the company’s internal currency.
• A strong team of engineers.
• Positive and friendly atmosphere.
