Job description

Position Summary:

Mirafra Technologies is seeking an experienced, highly technical, and accomplished Firmware & Low-Level Device Driver Developer with 3 to 6 years of professional firmware and embedded software engineering experience to join our client delivery team on a full-time basis in Bangalore, requiring an immediate to 30 days notice period. In this specialized embedded systems role, you will spearhead developing low-level device drivers, bare-metal firmware, and robust embedded software across advanced microcontroller and microprocessor architectures. You will work closely with cross-functional hardware design squads, silicon validation teams, and software architects to ensure highly optimized, reliable, and high-performance device control. Ideal candidates bring a robust academic background in electronics or computer engineering, deep practical mastery of Embedded C, RTOS, and hardware peripherals, and immediate availability for deployment in Bangalore.

Detailed Job Description:

As a Firmware & Low-Level Device Driver Developer at Mirafra Technologies in Bangalore, you will take full ownership of designing, implementing, debugging, and optimizing firmware and device drivers for next-generation embedded systems. Your day-to-day responsibilities encompass writing clean, efficient Embedded C code for bare-metal and RTOS environments, configuring MCU/MPU peripherals (I2C, SPI, UART, GPIO, ADC, PWM, CAN, USB), and performing rigorous hardware-software integration debugging using oscilloscopes, logic analyzers, and emulators. You will collaborate with hardware engineering teams to review schematics, validate silicon features, and optimize power and execution performance. Working in a fast-paced technology consulting environment, you will solve complex low-level concurrency challenges and deliver robust firmware solutions.

Key Responsibilities:

• Design, develop, test, and maintain robust low-level device drivers and firmware for embedded systems.
• Write highly optimized, clean, and modular Embedded C code for bare-metal and Real-Time Operating Systems (RTOS).
• Configure and manage MCU/MPU internal and external peripherals including I2C, SPI, UART, GPIO, ADC, PWM, CAN, and USB interfaces.
• Perform thorough hardware-software integration testing, debugging, and oscilloscope/logic analyzer trace analysis.
• Collaborate closely with hardware design squads, ASIC verification teams, and software architects in Bangalore.
• Optimize firmware memory footprint, interrupt latency, power consumption, and execution speed.
• Review hardware schematics, data sheets, and component errata to design accurate low-level abstraction layers.
• Establish automated unit testing and hardware-in-the-loop (HIL) verification frameworks for continuous integration.
• Maintain comprehensive technical documentation, register maps, driver specifications, and design verification reports.
• Mentor junior embedded engineers and contribute to technical peer reviews across project lifecycles.

Required Qualifications & Skills:

• Bachelor’s or Master’s degree in Electronics & Communication Engineering, Computer Science, Electrical Engineering, or a related field.
• 3 to 6 years of professional hands-on experience in firmware and embedded software development.
• Strong programming proficiency in Embedded C with deep understanding of pointers, memory management, and bit-manipulation.
• Proven practical experience developing low-level device drivers and bare-metal firmware.
• Hands-on familiarity with MCU/MPU architecture, startup code, interrupt service routines (ISRs), and memory maps.
• Practical working knowledge of communication protocols and peripherals: I2C, SPI, UART, GPIO, ADC, PWM, CAN, and USB.
• Experience developing applications on Real-Time Operating Systems (RTOS) or bare-metal execution environments.
• Professional availability for full-time employment in Bangalore, India (Immediate to 30 Days notice period).

Nice-to-Have Skills:

• Professional experience with ARM Cortex-M or Cortex-A microcontroller/microprocessor architectures.
• Familiarity with Linux kernel device driver development and board support package (BSP) customization.
• Prior working experience in automotive, consumer electronics, IoT, or semiconductor product companies.
• Experience using debugging tools such as JTAG, SWD, Lauterbach trace32, and protocol analyzers.
• Contributions to open-source embedded projects or published technical papers on low-level firmware optimization.

Recruitment Pro Tip:

When applying for embedded firmware roles, ensure your resume explicitly highlights your hands-on experience writing bare-metal Embedded C drivers, configuring hardware peripherals (SPI/I2C/UART/CAN), and working with RTOS environments.
