About the Role Job Title: Firmware Engineer Responsibilities: The Firmware Engineer is responsible for designing, developing, testing, and optimizing firmware for embedded systems and hardware devices. This role works closely with hardware engineers, software teams, and product managers to ensure seamless integration of software with electronic components, enabling reliable and efficient product performance.
- Firmware Development:
- Design, develop, and implement embedded firmware in C/C++, Assembly, and RTOS environments.
- Write low-level drivers for microcontrollers, sensors, communication modules, and peripherals.
- Develop, debug, and optimize code for constrained environments (memory, power, performance).
- Hardware Interaction & Integration:
- Work with hardware engineering teams to interpret schematics, datasheets, and component specifications.
- Bring-up of new hardware, board validation, sensor interfacing, and peripheral configuration.
- Perform firmware-hardware integration, troubleshooting, and performance tuning.
- Testing & Debugging:
- Create unit tests, integration tests, and system validation protocols.
- Use debugging tools like oscilloscopes, logic analyzers, JTAG, SWD, ICE, and protocol analyzers.
- Perform root-cause analysis for firmware bugs and hardware issues.
- System Architecture & Documentation:
- Contribute to system architecture, design decisions, and technical specifications.
- Develop and maintain documentation such as diagrams, firmware design, and API specs.
- Ensure compliance with coding standards and regulatory requirements.
- Communication Protocols & RTOS:
- Implement communication protocols: UART, SPI, I2C, CAN, USB, BLE, TCP/IP, MQTT, etc.
- Work with real-time operating systems (FreeRTOS, ThreadX, Zephyr, QNX, etc.).
- Optimize tasks for deterministic performance and low-latency responses.
- Continuous Improvement:
- Participate in code reviews, architecture discussions, and performance optimization efforts.
- Stay updated with embedded systems trends, new microcontroller platforms, and programming techniques.
Required Skills: Core Technical Skills:
- Strong expertise in C/C++ for embedded programming.
- Experience with microcontrollers (ARM Cortex, STM32, PIC, AVR, TI, ESP32, etc.).
- Hands-on knowledge of RTOS concepts and task scheduling.
- Firmware debugging using hardware tools and emulators.
