The Team

The Memory Validation team sits within the Validation organization and is responsible for the bring-up, validation, characterization and debug of memory subsystems across Graphcore silicon and platform products.

The team supports DDR and HBM validation activities throughout the product lifecycle, from first silicon through production readiness. Engineers work closely with architecture, RTL, firmware, characterization, systems and platform teams to ensure memory technologies meet functionality, performance, reliability and performance objectives.

Responsibilities and Duties

• Execute validation and bring-up activities for DDR and HBM memory subsystems
• Verify memory bring-up software, firmware and scripts against defined project requirements
• Debug firmware, hardware and system-level issues and contribute to root‑cause analysis activities
• Analyse system logs, validation data and characterization results to identify failures and performance issues
• Perform PHY characterization and analog‑level analysis during stress testing and validation activities
• Develop and execute functional, stress, performance and corner‑case validation tests
• Perform signal integrity, voltage, frequency and timing measurements using laboratory instrumentation
• Characterize memory bandwidth, latency, training behaviour and subsystem stability across operating conditions
• Develop Python‑based automation, test infrastructure and reporting tools to improve validation efficiency
• Collaborate with architecture, RTL, firmware and platform teams to investigate and resolve technical issues
• Contribute to memory subsystem debug activities spanning silicon, firmware, board and system domains
• Support development of validation methodologies, debug procedures and reporting frameworks
• Contribute to continuous improvement of validation infrastructure and engineering processes
• Support silicon characterization, production readiness and qualification activities
• Document validation results and communicate findings to the wider engineering team
