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
