About The Position

The Flipper team, creators of Flipper Zero and currently developing the BUSY Bar productivity multitool, is seeking a Senior QA Engineer with expertise in IoT, Embedded, and Cloud technologies. This role is crucial for designing and owning comprehensive test coverage for complex end-to-end scenarios that involve firmware, cloud services, and mobile applications. The goal is to ensure seamless and reliable interaction between devices, backend systems, and user applications.

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.
Hands-on experience testing REST or gRPC APIs using tools such as Postman, Swagger, or existing automated tests.
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.

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 scenarios like network failures, reconnections, timeouts, offline operation, and OTA update and rollback processes.
Test cloud and local APIs, business logic, data validation, and error handling to ensure reliable behavior across integration scenarios.
Analyze device and cloud logs (e.g., UART, syslog, Kibana, Sentry) to diagnose issues, verify command execution, and identify anomalies across system components.
Build test data and configuration strategies for various 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.
