Job description

Senior Manufacturing Test Engineer – AI Inferencing Systems

Sunnyvale, CA

Location: Sunnyvale, CA Experience Level: Senior (10–15+ Years) Onsite/Hybrid - San Francisco Bay Area

About the role

To keep pace in this exciting, multi-disciplinary field, we’re looking for a Sr. Manufacturing Test Engineer. You will be in a unique position to build the solution from the ground up:

• Architect & Develop the Solution: Develop the end-to-end Manufacturing Test Solution (ICT, FCT, Burn-in, and System Level Test) for high-performance AI servers.
• Own the Lifecycle: From NPI (New Product Introduction) to high-volume manufacturing (HVM), you will lead the deployment of test solutions at our Tier-1 Contract Manufacturers (CMs).
• Software & Automation: Develop and maintain sophisticated test scripts and automation frameworks that minimize human intervention and maximize throughput.
• Diagnostics & Utilities: Collaborate with Hardware and Software teams to leverage and/or develop custom diagnostics that functionally exercise and stress the AI accelerator, high-speed interconnects, and memory subsystems.
• This hands‑on multi-disciplinary role provides a unique opportunity to interact directly with ASIC, Hardware, and Software teams to gather necessary requirements and specifications, and develop and deploy the manufacturing test solution for a complex, high‑performance hardware system, from PCB and PCBA through full system‑level testing.

Responsibilities

• Strategy & Development: Define, design, and own the development of comprehensive manufacturing test strategies for hardware at the PCB, PCBA, and final system levels.
• Automation & Support: Develop and maintain automated manufacturing test solutions deployed within factory and contract manufacturing environments.
• Debugging & Root-Cause Analysis: Perform debugging and root‑cause analysis for hardware, board‑level, and system‑level failures encountered during manufacturing and product bring‑up.
• Cross‑Functional Collaboration: Collaborate closely with Hardware Design, Validation, Manufacturing, and Quality teams to ensure robust test coverage, drive yield improvement, and optimize manufacturability.
• Test Execution & Deployment: Support PCBA manufacturing testing, including Boundary Scan, Functional Test, and System Integration Testing, and partner with Contract Manufacturers for test deployment, sustainment, and issue resolution.
• Data Infrastructure: Develop test software, Graphical User Interfaces (GUIs), and supporting infrastructure necessary for manufacturing data collection, traceability, and analysis.

Qualifications

• Education: Bachelor’s degree in Engineering, Computer Science, or a closely related technical field.
• Experience: 10 or more years of experience in developing manufacturing tests for hardware products.
• Core Expertise: Demonstrated, hands‑on proficiency in:
• PCB and PCBA manufacturing test processes.
• Hardware validation and bring‑up procedures.
• Designing and developing tests within manufacturing settings.
• Manufacturing Support: Proven experience supporting PCBA manufacturing lines or working with contract manufacturers (CMs).
• Test Automation: Strong understanding of manufacturing test automation, including:
• Automated functional testing.
• Factory test infrastructure management.
• Test data collection and subsequent analysis.
• Software Development: Experience developing test software utilizing:
• Python and/or C/C++.
• Linux‑based operating environments.
• Tooling & Infrastructure: Familiarity with relevant test tooling and infrastructure, such as:
• GUI‑based test applications.
• Databases (e.g., MySQL / SQL).
• Cloud‑based systems (e.g., AWS) for managing test data and automation.
