About the job
Defines, designs, simulates, and validates signal and power integrity for AWS next-generation machine-learning ASIC platforms.
What you'll do
- Run high-speed channel simulations and SI/PI analyses to optimize signal integrity and PCB layouts.
- Analyze PCIe equalization, clock distribution, and jitter; troubleshoot signal-integrity issues.
- Collaborate with hardware and PCB teams on stack-ups, manufacturing trade-offs, and production reliability.
What they ask for
- Deep understanding of signal-integrity concepts and analytical skills in SI/PI.
- Hands-on experience with simulation tools and high-speed channel simulation, including system-level modeling and validation.
- Experience with PCIe protocols and DFE, CTLE, and FFE equalization; knowledge of clock distribution and jitter analysis.
- Expertise in PCB layout and manufacturing, including stack-up design, dielectric selection, impedance control, and layer optimization.
Nice to have
- Power-integrity analysis and power delivery network (PDN) optimization.
- High-speed compliance testing and validation, or EMC/EMI mitigation.
