Position Summary

Mirafra Technologies is actively seeking an experienced, high-caliber, and technical Firmware / Device Driver Developer with 2.5 to 6 years of progressive professional experience in embedded software engineering, low-level device driver development, and hardware-software integration to join our client engineering team on a full-time permanent on-site basis in Bangalore, India (embedded development only; application development and IoT profiles are not required). In this critical systems engineering and firmware development role, you will be responsible for designing, developing, testing, and optimizing bare-metal firmware, RTOS-based software, and kernel-level device drivers for complex semiconductor chips and electronic hardware. You will leverage your deep specialist expertise in C/C++, embedded microcontrollers, peripheral protocols, and hardware debugging to deliver uncompromised system reliability, high performance, and operational excellence. This opportunity offers competitive compensation, executive technical visibility, and exceptional career growth prospects within a premier global semiconductor and embedded engineering enterprise.

Detailed Job Description

As a Firmware / Device Driver Developer supporting Mirafra Technologies in Bangalore, India (embedded development only), you will take full operational, tactical, and technical ownership of low-level device driver implementation, board bring-up, peripheral configuration, and firmware optimization across mission-critical silicon platforms. Your day-to-day responsibilities include designing, writing, testing, and maintaining robust C and C++ source code for embedded processors, MCUs, and SoCs, implementing and validating device drivers for standard hardware peripherals (I2C, SPI, UART, USB, PCIe, DMA, GPIO, Timers), configuring, customizing, and debugging real-time operating systems (FreeRTOS, ThreadX) and bare-metal execution environments, collaborating closely with cross-functional hardware engineering, IC design, and QA squads in Agile sprint cycles, conducting rigorous oscilloscope debugging, logic analyzer tracing, JTAG debugging, and root cause analysis (RCA) to resolve complex low-level anomalies, preparing comprehensive technical documentation of firmware architectures, register maps, and operational runbooks, and managing application requirements by sending your updated resume via direct email to Susmita Ghosh at [e-mail] (please mention the position name in the email subject line). You will utilize your proactive troubleshooting and analytical problem-solving skills to resolve complex hardware interaction and timing bottlenecks under strict service level agreements. Furthermore, you will manage application requirements ensuring strict compliance with the 2.5 to 6 years experience requirement, pure embedded development focus, and Bangalore on-site presence.

Key Responsibilities

• Design, develop, test, debug, and maintain robust low-level firmware and device drivers utilizing C and C++ programming languages.
• Implement and validate drivers for core hardware peripherals including I2C, SPI, UART, USB, PCIe, DMA, and interrupt controllers.
• Execute systematic board bring-up, hardware debugging, oscilloscope verification, and logic analyzer profiling on new silicon.
• Configure, customize, and optimize Real-Time Operating Systems (FreeRTOS, ThreadX) or bare-metal execution loops.
• Collaborate seamlessly with cross-functional hardware engineering, IC design, and QA validation squads.
• Conduct rigorous code profiling, memory optimization, and power management tuning for resource-constrained embedded systems.
• Resolve complex timing anomalies, bus contention issues, and hardware interaction defects with rapid root cause analysis.
• Maintain accurate, comprehensive technical documentation of firmware specifications, API interfaces, and operational runbooks.

Required Qualifications & Skills

• Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical discipline.
• Minimum of 2.5 to 6 years of progressive professional experience in embedded systems design, firmware development, and device drivers.
