Embedded Firmware Engineer

Key Responsibilities

• Firmware Development: Design, develop, and debug embedded firmware in C/C++ for ARM Cortex-M based systems (STM32, AT32) and Espressif (ESP32) platforms.
• Hardware Interfacing: Develop low-level drivers and interface with hardware peripherals (GPIO, ADC, DAC, PWM) and communication protocols (UART, SPI, I2C, CAN, Modbus).
• IoT Connectivity: Implement Wi-Fi and Bluetooth Low Energy (BLE) functionality for IoT applications, including MQTT, HTTP, and TLS protocols, specifically on the ESP32 platform.
• RTOS Implementation: Develop multithreaded applications using FreeRTOS or similar Real-Time Operating Systems for real-time performance optimization.
• Debugging & Validation: Perform board bring-up, troubleshooting, and validation using debugging tools such as JTAG, SWD, oscilloscopes, and logic analyzers.
• Optimization: Optimize firmware for performance, memory management, and power consumption.
• Documentation & Collaboration: Collaborate with hardware designers to ensure seamless integration, maintain technical documentation, and adhere to version control (Git) standards.

Required Skills & Qualifications

• Education: Bachelor’s degree in Electronics/Electronics & Communication, Computer Engineering, or related field.
• Programming: Proficiency in Embedded C (essential) and C++.
• Microcontrollers: Strong hands-on experience with STM32 (CubeMX/HAL) and ESP32 (ESP-
  IDF or Arduino IDE).
• Architectures: Experience with ARM Cortex-M architectures (STM32/AT32).
• Protocols: In-depth knowledge of communication interfaces (I2C, SPI, UART).
• Tools: Proficient with Git, GDB, and JTAG debugging tools.

Preferred Skills (Good to Have)

• Experience with STM32 microcontrollers.
• Familiarity with Embedded Linux.
• Experience in secure boot and OTA (Over-the-Air) firmware updates.
• Scripting knowledge (Python) for automated testing
