Senior Test Automation Engineer with deep test automation expertise to support an e-banking platform for a BFSI client. You will own test automation strategy and execution across iOS, Android, and web banking applications, ensuring releases meet high standards for quality, security, and reliability in the Swiss regulated financial sector. In this senior role you will act as a quality champion — defining frameworks, mentoring engineers, and collaborating with developers, product owners, and security teams to embed quality throughout the software delivery lifecycle.

• Test Strategy & Architecture:
  Define and own the end-to-end test automation strategy across mobile (iOS & Android) and web channels; design, build, and maintain scalable test frameworks using industry-standard tooling (Appium, Detox, XCUITest, Espresso, Playwright/Cypress); establish test pyramid guidelines and drive adoption across squads; lead risk-based test planning for regulated financial features (payments, authentication, account management).
• Mobile Test Automation (iOS & Android):
  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, Git Hub 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.
• Web Test Automation:
  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 & Graph
  
  QL) to decouple frontend from backend test cycles.
• CI/CD & Quality Engineering:
  Integrate automated tests into CI pipelines for fast, reliable feedback on every pull request; define and monitor quality metrics (test coverage, flakiness, defect escape, MTTD); implement performance and load testing for critical banking transactions using k6 or JMeter; champion shift-left testing practices and contribute to developer-written testability.
• Security & Compliance Testing:
  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); support audit and compliance activities with test evidence, traceability matrices, and reporting.

• Must-Haves:
  • 3+ years of professional experience in test automation, with at least 2 years in a senior or lead QA role
  • Hands-on expertise in mobile (iOS + Android) and web test automation
  • Strong programming skills in Python or Type Script; ability to write clean, maintainable test code
  • Experience with CI/CD integration of automated test suites in a real production environment
  • Solid understanding of software testing principles: test pyramid, BDD, risk-based testing
  • Experience working in agile teams on complex, multi-platform digital products
• Nice-to-Haves (Plus):
  • Background in financial services, banking, or another regulated industry
  • Experience with SAFe at scale or multi-team test coordination
  • Knowledge of FINMA digital banking guidelines or PSD2/open banking testing requirements
  • Hands-on experience with performance and security testing
  • ISTQB Advanced Level (Test Analyst or Technical Test Analyst) certification
  • Languages:
    
    German (fluent, B2+), English (business proficient);
    French or Italian advantageous
