From software to hardware our teams are shaping the future of world-leading hyperscale computing, with key teams working on the development of our TPUs, Vertex AI for Google Cloud, Google Global Networking, Data Center operations, systems research, and much more.

Responsibilities

• Develop physical package substrate design of large form-factor package for ML high-performance computers (HPCs).
• Develop and implement the methodology and CAD flow for efficient substrate design and enhanced productivity.
• Manage and drive co-design initiatives across chip, package, and system levels, including securing production sign-off for package designs.
• Collaborate closely with signal integrity/power integrity (SI/PI), thermal, and mechanical engineering teams to refine and optimize product package designs, test vehicles, and mock-up designs for product feasibility.
• Define and document the requirements for the package substrate design and bill of materials (BOM).

Qualifications

Minimum qualifications:

• Bachelor's degree in Mechanical Engineering, Material Engineering, Electrical Engineering, Technology, Science, a related field, or equivalent practical experience.
• 8 years of experience in chip package substrate design using Cadence APD or Mentor Expedition.
• Experience in chip package substrate layout, design verification, DFM and taping out for production.
• Experience in design automation and scripting.

Preferred qualifications:

• Master's degree or PhD in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
• Experience in working with cross functional teams including chip design, SI/PI, and PCB design teams.
• Experience in 2.5D/3.5D advanced package design.
• Experience in physical verification flow (LVS, DRC, connectivity).
• Experience with CAD for creating simple mechanical drawings, such as package outline drawings (POD).
• Ability to write scripts to customize elements of the Cadence or Mentor workflow.
