• In this role, you will lead the development and deployment of System Level Test (SLT) solutions for next-generation AI processors
• Working closely with cross-functional teams, you will contribute to the design and implementation of SLT hardware, software, automation, and characterization solutions that support silicon bring-up, yield learning, manufacturing readiness, and production deployment
• The Product Test and Diagnostics team’s role is to detect and manage hardware defects that arise from the manufacture and use of our products. This covers chips, boards and finished systems and takes place both in the manufacturing sites and in the field
• Lead development and deployment of SLT hardware and software solutions supporting silicon bring-up, characterization, yield learning, and manufacturing deployment
• Own major SLT workstreams and drive execution from requirements definition through deployment and production readiness
• Develop and integrate SLT test content in collaboration with Silicon Validation, Bring-up, Product Engineering, and Manufacturing teams
• Lead development of SLT hardware including test boards, sockets, thermal solutions, instrumentation, and vendor engagements
• Develop and maintain SLT software frameworks, automation infrastructure, diagnostics, telemetry collection, and data analysis tools
• Drive characterization activities including voltage margining, frequency characterization, thermal characterization, and reliability screening
• Lead debug, failure analysis, root-cause investigations, and correlation activities across Simulation, ATE, Bench, SLT, and manufacturing environments
• Define and optimize test coverage, test time, screening effectiveness, DPPM, and manufacturing test strategies
• Support transfer of SLT solutions into OSAT and contract manufacturing environments and provide production ramp support
• Work closely with DFT teams to understand testability, observability, scan architectures, and manufacturing test requirements
• Contribute to definition of future SLT architectures, methodologies, and infrastructure requirements
• Mentor junior engineers and provide technical leadership within the team
• Drive technical reviews, project planning, risk management, and execution tracking for assigned workstreams
• Collaborate with external vendors and industry partners to evaluate and deploy SLT platforms and solutions
