Senior DDR & Execution Validation Engineer

Job Summary

Reporting to the Memory Validation leadership team, the Senior Silicon DDR/HBM Validation Engineer will be responsible for the bring-up, validation, characterization and debug of advanced memory subsystems used in next-generation AI compute platforms.

The role will focus on DDR and HBM technologies, working closely with silicon design, firmware, characterization, platform and systems teams to ensure robust memory subsystem functionality, performance and reliability. The successful candidate will take ownership of significant validation activities, contribute to debug and root-cause analysis efforts, and help improve validation methodologies, automation and infrastructure.

The Team

The Memory Validation team sits within the Validation organisation 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, performan
