Embedded medical devices and connected health platform

广州市, 广东省 ~2 employees
rainjet.net LinkedIn

Rainjet is a small embedded systems and medical device company operating primarily in China, with a stack spanning firmware (FreeRTOS, STM32, CAN, UART), mobile (Android, Java, C++), and backend services (Python, HTTP/FTP). The sales-heavy department mix (11 sales vs. 5 engineering) paired with active projects in live streaming, user acquisition, and education-sector expansion suggests a push toward consumer or institutional distribution rather than pure hardware—likely mobile or cloud-connected health monitoring devices.
