- Proficient in C programming language, with the ability to read and understand embedded software code to assist in problem analysis and white-box testing.
- Solid hardware fundamentals. Ability to read schematics and use common test equipment like multimeters, oscilloscopes, and logic analyzers for debugging.
- Familiar with embedded software development and testing life cycles, as well as common defect management processes.
- Strong written English proficiency (CET-4 or equivalent minimum), with the ability to read English technical documentation, chip datasheets, and write English test reports.
- Preferred Qualifications:
- Experience using Python or other scripting languages to develop automated test tools.
- Understanding of the fundamentals of RTOS (e.g., FreeRTOS, uC/OS) or embedded Linux.
- Basic knowledge of network protocols (e.g., TCP/IP, HTTP, SNMP).
- Exposure to Continuous Integration/Continuous Deployment (CI/CD) concepts or tools (e.g., Jenkins, Git).
