Senior SLT Test Engineer

Job Summary

We are looking for an experienced System Level Test Engineer to join our Product Test and Diagnosis Department (PTD).

In this role, you will contribute to the development and deployment of System Level Test (SLT) solutions for next-generation AI processors. Working closely with hardware, software, validation, and manufacturing teams, you will develop test content, automation, diagnostics, and characterization capabilities that support silicon bring-up, yield learning, and manufacturing deployment.

The ideal candidate will have strong technical foundations in semiconductor test and validation, excellent debug skills, and a passion for improving product quality and manufacturability.

The Team

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.

Responsibilities and Duties

• Develop and maintain SLT test content, automation, diagnostics, and characterization workloads for silicon bring-up and manufacturing readiness activities.
• Execute characterization, voltage/frequency margining, reliability screening, and performance correlation activities while analyzing results and identifying improvement opportunities.
• Support development and deployment of SLT hardware including test boards, sockets, instrumentation, and thermal solutions.
• Integrate validation and bring-up workloads into the SLT environment and support development of manufacturing screening solutions.
• Debug failures, perform root-cause analysis, and support correlation activities across Simulation, ATE, Bench, SLT, and manufacturing environments.
• Develop software tools, scripts, and automation flows for test execution, telemetry collection, data analysis, and reporting.
• Contribute to improvements in test coverage, test-time optimization, DPPM reduction, and manufacturing readiness.
• Work closely with Design, DFT, Silicon Validation, Product Engineering, Manufacturing, and OSAT teams to support product development and deployment activities.
• Support transfer of SLT solutions into production environments and assist with manufacturing ramp activities.
• Mentor junior engineers and contribute to continuous improvement of SLT methodologies and best practices.

Minimum Qualifications

• Experience in semiconductor test, validation, characterization, post-silicon bring-up, or manufacturing environments.
• Understanding of semiconductor fundamentals, digital systems, power delivery, signal integrity, and board-level debugging.
• Familiarity with DFT concepts including scan, JTAG, BIST, MBIST, boundary scan, and manufacturing test methodologies.
• Experience with Python, Tcl, Shell, or similar scripting languages for automation and data analysis.
• Strong debug, problem-solving, root-cause analysis, and data interpretation skills.
• Experience working with cross-functional teams including Design, DFT, Validation, Product Engineering, or Manufacturing.
• Bachelor's degree in Electrical Engineering, Computer Engineering, or related field.

Preferred Qulaifications

• Familiarity with advanced packaging, chiplets, or high-performance computing products.
• Experience with manufacturing test and production environments, along with OSAT engagement.
