Quality Assurance Engineer, Swiss POS Product

What you’ll do

• Plan and execute test cycles for Android POS app versions: smoke, regression, and exploratory
• Verify releases end-to-end: changelog validation, build sanity, OTA/update flows, and final sign-off
• Perform ticket verification: reproduce, validate fixes, and close with clear evidence and test notes
• Test on physical POS devices (e.g., K6-class terminals): peripherals (printers, scanners, card readers), EMV/NFC, receipts
• Validate critical POS user flows: checkout, refunds/voids, settlements, offline/poor-network scenarios
• Manage device/OS matrix: Android versions, form factors, firmware, and compatibility impacts
• Design, author, and maintain high-quality test cases and edge-case scenarios for core flows
• Design and execute API tests for POS-related backend services: validate request/response payloads, error handling, and contracts that support mobile flows
• Capture diagnostics for defects: logs, screenshots, videos, ADB traces; provide precise repro steps
• Collaborate with engineering/product to define acceptance criteria and improve testability
• Track quality signals and risks; prioritize test coverage based on impact and usage
