Job Description

About Raiton Semiconductor

Founded in 2018 and headquartered in Bengaluru, Raiton Semiconductor is a specialized semiconductor services company. We provide ASIC/FPGA design, hardware verification, and pre- & post-silicon validation, along with FPGA/HLS prototyping for next-generation SoCs. Our end-to-end expertise enables faster development cycles, reduced costs, and high-quality, reliable chip solutions for global clients.

About Role

We are seeking a skilled Bare Metal Firmware Engineer with hands-on experience in developing low-level software for ARM and RISC-V architectures. The candidate will be responsible for writing, optimizing, and debugging firmware that interacts directly with hardware, ensuring performance, stability, and power efficiency in embedded systems and SoCs.

Key Responsibilities

• Design, develop, and maintain bare-metal firmware on ARM Cortex-M/A and RISC-V cores.
• Implement bootloaders, board bring-up, and low-level drivers (UART, SPI, I2C, GPIO, timers, watchdog, interrupts, etc.).
• Work closely with hardware teams to validate SoC/IP functionality, perform board bring-up, and support silicon validation.
• Debug hardware/software issues using JTAG, GDB, logic analyzers, and oscilloscopes.
• Develop firmware for power management, clock management, and low-power states.
• Contribute to secure boot, memory protection, and exception handling implementations.
• Optimize firmware for performance, latency, and memory footprint.
• Write unit tests, validation frameworks, and documentation for developed firmware.
• Collaborate with cross-functional teams (hardware, DV, system architects, and verification) to ensure end-to-end system integration.
  
  

• 4+ years of professional experience in embedded firmware development.
• Strong knowledge of ARM Cortex-M/A architecture and RISC-V ISA.
• Hands-on experience with bare-metal programming (no RTOS).
• Proficiency in C, C++, and Assembly for embedded platforms.
• Deep understanding of memory maps, MMU/MPU, cache, and exception handling.
• Experience with bootloaders, startup code, linker scripts, and memory initialization.
• Familiarity with AHB/APB bus protocols and low-level peripheral programming.
• Strong debugging skills with JTAG/SWD, GDB, Lauterbach, OpenOCD.
• Exposure to SoC bring-up and pre/post-silicon validation.
• Knowledge of version control (Git), CI/CD flows, and code quality practices.
