## Description

We are seeking a dedicated Firmware Test Engineer to execute manual firmware testing, including functional, regression, integration, and stress testing. You will develop and maintain test plans, test cases, and test documentation based on firmware requirements. The role involves performing hardware-in-the-loop (HIL) and software-in-the-loop (SIL) testing, identifying, documenting, and tracking firmware defects, and collaborating with developers to ensure resolution. The candidate will validate firmware behavior across embedded systems and connected IoT devices, support cross-platform and compatibility testing, assist with user acceptance testing (UAT), and final release validation. Using lab and debug tools, you will troubleshoot firmware and communication issues while contributing to the continuous improvement of testing processes and best practices.
