Job description

Hi! This is the Flipper team.

We are the creators of Flipper Zero — a portable device for tech enthusiasts and engineers. It's a gadget with an awesome community that brings together millions of people around the world.

We are currently developing a new product — the BUSY Bar productivity multitool. It's a smart device that helps you stay focused and minimize distractions.

We're looking for a Senior QA Engineer (IoT / Embedded & Cloud) to design and own test coverage for complex E2E scenarios spanning firmware, cloud services, and mobile applications, ensuring reliable interaction between devices, backend systems, and apps.

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

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

What we offer

• Choose your work format: office, hybrid, or fully remote from anywhere in the world

• You will be provided with all the necessary equipment for a comfortable working environment

• Benefits such as VHI, corporate sports, foreign language courses, and therapy sessions

• A five-day workweek with a flexible start of the working day
