Key Responsibilities

• Design, develop, test, debug, and maintain embedded firmware for IoT and smart automation products.
• Develop firmware using Embedded C/C++ for microcontroller‑based systems.
• Work with microcontrollers/platforms such as ESP32, ESP8266, or similar controllers.
• Develop and integrate communication interfaces and protocols including UART, SPI, I2C, RS485, and MQTT.
• Work with wireless technologies such as Wi‑Fi and Bluetooth Low Energy (BLE).
• Integrate embedded devices with gateways, servers, cloud platforms, and other connected systems.
• Perform hardware bring‑up, firmware debugging, PCB‑level testing, and hardware software integration.
• Identify and troubleshoot firmware, communication, and hardware‑related issues through systematic root‑cause analysis.
• Optimize firmware for memory utilization, processing efficiency, communication performance, stability, and reliability.
• Develop and maintain bootloaders, firmware upgrade mechanisms, and OTA update functionality as required.
• Support the development of device telemetry, diagnostics, and remote troubleshooting mechanisms.
• Develop test utilities and contribute to automated testing and production testing of embedded devices.
• Support product testing, field troubleshooting, issue resolution, and continuous improvement of deployed products.
• Collaborate with hardware, cloud, application, testing, and product teams throughout the product development lifecycle.
• Maintain appropriate technical documentation for firmware, device configurations, testing, and troubleshooting.

Required Technical Skills

• 2+ years of hands‑on experience in Embedded Systems / Firmware Development.
• Strong programming skills in Embedded C/C++.
• Hands‑on experience with microcontrollers such as ESP32/ESP8266, NRF52 or equivalent platforms.
• Practical experience with communication protocols such as: UART, SPI, I2C, RS485
• Experience working with Wi‑Fi, Bluetooth Low Energy (BLE) and ZigBee
• Good understanding of microcontroller architecture, peripherals, interrupts, memory management, and embedded communication.
• Ability to read and understand electronic schematics and PCB designs.
• Hands‑on experience in firmware debugging, hardware troubleshooting, and hardware software integration.
