About The Position

As a Principal System Debug Engineer, you will lead the system-level debug of our advanced microprocessors within complex customer applications and system design environments. You will act as the critical bridge between our internal silicon/software engineering teams and our top-tier OEM, ODM, and Hyperscaler customers. This is a highly visible, cross-functional leadership role that requires deep technical expertise in CPU architecture, high-speed I/O interfaces, firmware/BIOS, system software, drivers, OS/kernels and software stacks, and platform hardware design, signal integrity, power integrity. You will drive the investigation, root-cause analysis, and resolution of the most complex, system-level CPU issues in the context of new system bring-up and customer applications and platform level debug.

Requirements

Deep, foundational knowledge of modern CPU architectures (x86 mandatory), including pipelines, cache coherency, memory controllers, and power management (C-states, P-states). RAS features, MCA (Machine Check Architecture), SoC and platform security features, RoT (root-of-trust).
Extensive expertise in the architecture and protocol-level debug of high-speed I/O interfaces, including PCIe (Gen 4/5/6), CXL, DDR4/DDR5, Ethernet, USB, and low-speed buses (I2C, SPI, I3C, eSPI).
Strong understanding of the full system software stack, including BIOS/UEFI, BMC/IPMI, Linux/Windows kernel internals, device drivers, and hypervisors (KVM, VMware, Hyper-V).
Solid grasp of system-level hardware design, including board schematics, PCB layout, power delivery networks (VRMs), clocking, and signal integrity fundamentals.
Proven track record of performing complex system bring-up and debug using hardware tools (JTAG/ITP debuggers, oscilloscopes, logic analyzers, protocol analyzers) and software debuggers (GDB, WinDbg, kernel panics/crash dump analysis).
Experience working directly with Cloud Service Providers (Hyperscalers) and Tier-1 Server/Client OEMs.
Proficiency in scripting and programming languages (Python, C, C++) for test automation and debug tool development.
Hands-on expertise in debugging hardware (system bring-up, signal integrity, power integrity issues) and debugging firmware/software running on actual hardware platforms.
Experience with RAS (Reliability, Availability, and Serviceability) architecture and machine check exception (MCE) analysis.
Bachelor’s, Master’s, or PhD in Electrical Engineering, Computer Engineering, Computer Science, or a related field.

Responsibilities

Lead the triage, investigation, and root-cause analysis of complex system-level issues involving CPU silicon, platform hardware, firmware, drivers and OS/hypervisor interactions in customer environments.
Drive early platform bring-up activities for next-generation CPUs, both in internal labs and on-site at customer facilities, ensuring rapid time-to-market.
Serve as the primary technical liaison for strategic customers. Guide customer engineering teams through platform design, debug methodologies, and issue resolution.
Partner closely with internal Silicon Design, Architecture, Firmware (BIOS/UEFI/BMC), OS/Kernel, and Validation teams to drive systemic fixes and influence future CPU architectures based on customer feedback.
Architect and develop advanced debug methodologies, scripts, and tools to accelerate issue isolation across the hardware/software boundary.
Act as the technical task force leader during critical customer escalations, providing clear executive updates and driving technical action plans under tight deadlines.
