Job Description

About the Team

We are Quadcode, a fintech company excelling in financial brokerage activities and delivering advanced financial products to our global clientele. Our flagship product, an internal trading platform, is offered as a Software-as-a-Service (SaaS) solution to other brokers.

We are looking for a Mobile QA Engineer for our iOS team.

We are currently undertaking a major redesign of our flagship trading platform, used by millions of users worldwide, with three key goals: delivering an adaptive UI across different screen sizes and device families, expanding automated regression coverage, and transitioning to native Swift-based test automation.

We follow an AI-first approach, actively 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 end to end, from reviewing requirements and identifying potential risks to designing test cases, executing manual tests, and automating them where appropriate.

Our ideal candidate has a strong product mindset, takes ownership of features, proactively identifies issues and opportunities for improvement, collaborates with different teams, and drives features through testing to a successful release.

Tasks

• Manual Testing: Perform functional, regression, smoke, end-to-end and integration testing of 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: Help migrate the existing test automation framework to Swift-based automation, improving 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, helping ensure reliable execution and timely feedback on product changes.
• AI-Assisted Workflows: Use AI tools in day-to-day 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, API automation tools such as REST Assured, Retrofit, or requests, etc.). 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.
