SEPLE manufactures embedded security hardware (CCTV, fire alarms, access control, cash management) using microcontroller stacks (STM32, ESP32) paired with IoT protocols (MQTT, BLE, Ethernet). The tech footprint—heavy on firmware (RTOS, UART, I2C, RS485) with minimal cloud adoption—reflects a hardware-first business model serving on-premise physical security. Hiring skews junior engineering (12 of 19 roles), suggesting either high operational churn or capacity-building for scale in field deployments and maintenance contracts.
