Senior Test Automation Engineer

Define and own the end-to-end test automation strategy across mobile (iOS & Android) and web e-banking channels. Design, build, and maintain scalable test frameworks using industry-standard tooling (Appium, Detox, XCUITest, Espresso, Playwright/Cypress). Establish test pyramid guidelines — unit, integration, E2E — and drive adoption across squads. Lead risk-based test planning for regulated financial features (payments, authentication, account management). Implement and maintain automated UI and functional test suites for native iOS (Swift/ObjC) and Android (Kotlin) apps. Integrate mobile test runs into CI/CD pipelines (Bitrise, GitHub Actions, Fastlane). Configure and manage device farms (Browserstack, Firebase Test Lab, or on-premise device pools). Validate biometric authentication flows, deep links, push notifications, and offline behaviour. Build robust cross-browser E2E and component test suites for the web banking portal (React/Angular). Implement accessibility testing (axe-core, WCAG 2.1 AA) and ensure compliance across supported browsers. Create and maintain API/contract tests (REST & GraphQL) to decouple frontend from backend test cycles. Integrate automated tests into CI pipelines ensuring fast, reliable feedback on every pull request. Define and monitor quality metrics: test coverage, flakiness rates, defect escape rates, and mean-time-to-detect. Implement performance and load testing for critical banking transactions using k6 or JMeter. Champion shift-left testing practices and contribute to developer-written testability. Coordinate with the security team on automated OWASP-aligned security checks embedded in CI. Validate encryption, certificate pinning, and secure storage on mobile in line with Swiss financial regulations (FINMA guidelines). Support audit and compliance activities with test evidence, traceability matrices, and reporting.
