Senior Debug Validation Engineer

Graphcore is seeking a Senior Debug Validation Engineer to join their Architecture and Validation team in Bengaluru. The role focuses on driving post-silicon debug and validation activities for next-generation AI compute silicon and systems. The successful candidate will lead efforts to identify, reproduce, analyze, and resolve complex silicon, firmware, and system-level issues throughout the product lifecycle, from bring-up to production readiness.

Key Responsibilities:

• Lead post-silicon debug and validation activities for AI compute silicon and platform technologies.
• Investigate and resolve complex issues across silicon, firmware, software, and system levels.
• Develop structured debug methodologies and failure analysis processes to improve efficiency.
• Collaborate with architecture, RTL, firmware, software, and systems engineering teams to identify root causes and implement corrective actions.
• Drive debug of CPU, memory, interconnect, and high-speed I/O subsystems.
• Develop automated debug, regression, and validation infrastructure using Python.
• Define validation metrics, debug workflows, and reporting standards.

Required Qualifications

• Strong experience in bare metal environments and post-silicon validation in digital ASIC environments.
• Expertise in debug infrastructure, scan, DFT, JTAG, and trace infrastructure.
• Strong programming skills in Python, C, or debug scripting languages (e.g., CMM).
• Deep knowledge of SoC and platform architectures.
• Excellent problem-solving, analytical, and diagnostic skills, including fault tree analysis and failure isolation.
• Strong Linux experience and exceptional communication skills.

Preferred Qualifications

• Understanding of DFT flows, driver-level experience with PCIe, Ethernet, memory technologies (LPDDR, DDR, HBM), and peripheral interfaces (I2C, I3C, SPI).
• Experience with debug tools such as CoreSight, CTI, ETx, DStream, JLink, and Lauterbach.
• Knowledge of mixed-signal building blocks, Arm CPU architectures, AMBA protocols, and ML applications.
