Responsibilities
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

Experience analyzing device logs such as UART or syslog and cloud logs using tools such as Kibana or Sentry, with a basic understanding of embedded systems architecture

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
