Full Description
该职位来源于猎聘 Short Description: Under guidance, design simple test cases per FW requirements, execute functional/stability tests and assist in setting up test environments; record test logs/defects in tools like JIRA, and verify defect fixes with FW engineers; assist in compiling basic test documents (plans, cases, reports) and maintaining document versions; attend FW reviews to provide basic feedback, communicate with dev teams on defects, and learn testing skills from seniors while sharing progress Experience: 0-2 years of FW testing experience (embedded systems preferred: telecom, consumer electronics, IoT); New graduates with basic embedded/FW knowledge are welcome. Familiar with basic FW testing processes: test case design, test execution, defect recording. Able to use common testing tools: oscilloscope, multimeters, serial tools (e.g., SecureCRT), basic debuggers (J-Link/ST-Link). Basic understanding of communication protocols (UART, SPI) or embedded OS (e.g., FreeRTOS) is a plus. Elementary C language skills (able to read simple code) and familiarity with test tools (e.g., JIRA) are preferred. Special Skills: Design basic test cases based on FW requirements (cover functional and simple scenario test points). Assist in building and maintaining FW test environments (hardware setup, software configuration). Execute test cases, record test results and defects clearly. Coordinate with FW engineers to verify defect fixes. Assist in compiling simple test reports and organizing test documents. Participate in team meetings and learn from senior engineers to improve skills.
