SEPLE operates a 40-year-old electronic security business built on embedded systems (STM32, ESP32, MQTT, BMS) and IP-based surveillance. The tech stack—protocol-heavy with UART, I2C, RS485, and RTOS—reflects a legacy hardware-firmware organization now adopting IoT connectivity. Hiring remains heavily weighted to junior engineers (10 of 14 roles), suggesting either scaling manufacturing test/support or onboarding for feature development; sales velocity is accelerating despite stated pain around revenue generation and relationship growth.
