Summary

We are looking for an Embedded Firmware Engineer for a short-term project focused on ESP32-based firmware development. The work involves building and refining firmware for a connected IoT device using ESP32 and FreeRTOS. The main focus is on implementing core device functionality, handling hardware communication, and ensuring stable performance on real hardware. The ideal candidate should have strong experience in embedded C/C++ development and hands-on experience with ESP32 firmware projects. You should be comfortable working with FreeRTOS-based systems and implementing low-level peripheral communication such as UART, SPI, and I2C. Experience in debugging firmware directly on hardware using tools like JTAG, serial logs, or logic analyzers is required. This project requires the ability to understand hardware schematics at a basic level and translate them into working firmware. Experience with Git for version control and structured firmware development is also required. This is a short-term engagement aimed at delivering a working firmware prototype and stabilizing device-level functionality for testing and early deployment.
