Embedded Software Engineer NPU RTOS and Embedded Linux

You will develop and maintain RTOS-based firmware for heterogeneous multicore accelerator systems and lead its transition to Embedded Linux. You will define system architecture, build kernel drivers and images, migrate RTOS services, implement power-management and observability features, and debug issues on emulation and hardware platforms.

Responsibilities

• Define software requirements and system architecture with hardware engineers, driver developers, and product managers
• Design core allocation and kernel-to-userspace functional allocation
• Develop and maintain RTOS firmware for heterogeneous multicore and multichiplet systems
• Develop kernel-porting layers, task and service structures, interrupt schemes, and device drivers
• Lead technical evaluation, proof of concept, and migration planning for Embedded Linux
• Rebuild RTOS services as kernel drivers and userspace daemons
• Perform Linux kernel bring-up and develop device drivers for PCIe, DMA, interrupts, and mailboxes
• Build Yocto- and Buildroot-based images
• Develop and stabilize PCIe and SR-IOV device firmware
• Implement power management and observability infrastructure
• Reproduce and debug issues in CI regression environments on emulation platforms, EVBs, and hardware

Requirements

• At least 6 years of embedded software development experience
• Experience developing for ARM Cortex-M and ARMv8-A Cortex-A environments
• Bachelor’s degree or higher in Computer Science, Electrical Engineering, or a related field
• Experience with commercial RTOS platforms such as FreeRTOS, Zephyr, or ThreadX
• Linux kernel programming experience, including modules, device drivers, Device Tree, synchronization, interrupts, DMA, and memory mapping
• Knowledge of interrupt handling, memory management, low-level software, and assembly programming
• Knowledge of real-time systems and priority-based preemptive scheduling
• Experience developing device drivers and protocols including PCIe, UART, SPI, and I2C
• Ability to use JTAG debuggers, RTOS-aware tracing, ftrace, perf, and kgdb
• Experience with GCC cross-toolchains and CMake
