Firmware Developer

Mirafra; Bengaluru; On-site; INR 900,000 - 1,500,000; Full time

Job summary

Mirafra is seeking a firmware engineer to develop, port, and debug bare-metal and RTOS-based firmware for pre-silicon FPGA/emulation platforms. The role involves crafting and integrating drivers for low- and high-speed interfaces, and collaboration with hardware, DV, and software teams to validate system functionality.

The ideal candidate will have hands-on experience in bare-metal firmware and driver development, a strong C programming background, and proficiency with JTAG debugging.

Qualifications

• 3–10 years of hands-on experience in bare-metal firmware and driver development.
• Strong background in RTOS-based firmware development (FreeRTOS/Zephyr or similar).
• Excellent proficiency in C programming with solid debugging using JTAG or equivalent tools.
• Experience in bootloader bring-up.
• Strong knowledge of low-speed I/O interfaces (SPI, QSPI, I2C, UART).

Responsibilities

• Develop, port, and debug bare-metal and RTOS-based firmware for pre-silicon platforms (HAPS, ZeBu, or equivalent).
• Develop and integrate low- and high-speed IO drivers (SPI, QSPI, I2C, UART; PCIe, USB, eMMC, SD).
• Collaborate with hardware, DV, and software teams to validate pre-silicon system functionality.
• Use JTAG, debuggers, and trace tools to identify and resolve firmware and driver issues.
• Implement and validate firmware on RTOS environments such as FreeRTOS or Zephyr.
• Contribute to boot flow debugging, firmware optimization, and platform stability in early hardware validation.
• Document debug findings, bring-up procedures, and firmware design specifications.
