Substrate IC Package Layout Design Engineer

The role

You will lead the end-to-end design of complex IC substrate packages for high-power AI processors. This involves designing large multi-layer substrates, high-speed signal routing, and optimizing CoWoS interposer designs.

What you will do

• Lead the design and development of complex IC substrate layouts for high-power AI processors and accelerators.
• Design large and complex multi-layer substrate packages with high pin counts and dense routing requirements.
• Ensure robust power delivery designs capable of supporting >700W custom silicon solutions.
• Develop high-speed signal routing solutions capable of supporting >50GHz signaling.
• Collaborate with SI/PI engineers to define signal integrity and power integrity requirements.
• Optimize CoWoS interposer designs for thermal and electrical performance.
• Work with chip design, packaging, and manufacturing teams to ensure design feasibility and manufacturability.
• Perform DRC and LVS verification for all substrate designs.
• Develop and maintain design documentation and guidelines.
• Support design reviews and provide technical guidance to junior team members.

Required qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
• 10+ years of experience in IC substrate layout design for high-performance processors or accelerators.
• Extensive experience with large substrate packages (>50mm) and complex high-density layouts.
• Proven experience with high-power (700W+) package designs and robust power delivery networks.
• Expertise in high-speed signaling design (>50GHz) and mitigating signal integrity challenges.
• Strong experience with CoWoS (Chip-on-Wafer-on-Substrate) interposer design.
• Advanced proficiency in Allegro Package Designer.
• Deep understanding of SI/PI principles.
• Strong analytical skills.
