Design E2E test coverage across firmware, cloud, and mobile applications to verify device state, data consistency, and end-to-end behavior
Test device-to-cloud communication, including network failures, reconnections, timeouts, offline operation, and OTA update and rollback scenarios
Test cloud and local APIs, business logic, data validation, and error handling to ensure reliable behavior across integration scenarios
Analyze device and cloud logs to diagnose issues, verify command execution, and identify anomalies across system components
Build test data and configuration strategies for different device types, users, environments, and complex scenarios involving multiple devices
Identify and prioritize E2E scenarios for automation, define test specifications for automation engineers, and maintain stable smoke and regression testing processes
Requirements
Strong QA experience with complex software products and the ability to design test coverage across firmware, backend APIs, and mobile applications
Strong requirements analysis and systems thinking, with the ability to identify dependencies and integration points across devices, cloud services, and applications

Experience testing native or cross-platform mobile applications that interact with devices via BLE or Wi-Fi and cloud services
Experience working in Agile/Scrum environments, building QA processes, managing test artifacts in Jira, Confluence, TestRail, Qase, or TestOps, and defining scenarios for test automation
English proficiency sufficient for reading technical documentation and communicating with an international team
Nice-to-haves
Experience testing IoT or smart devices, including OTA updates, connectivity loss and recovery, and offline operation
Basic Python or JavaScript skills for creating simple test utilities, generating test data, parsing logs, or understanding automated tests
Experience with device simulators or emulators, network traffic analysis tools such as Wireshark or tcpdump, or security testing of device-to-cloud integrations
