$182,000 - $273,000 USD yearly
Drive power modeling, analysis, optimization, management, convergence, and validation across CPU, AI accelerator, memory, I/O, and interconnect designs.
About the role
Ampere is looking for a Principal Power Architect to drive power modeling, analysis, optimization, management, convergence, and validation across CPU, AI accelerator, memory, I/O, and interconnect designs.
What you'll do
- Define power targets, budgets, operating points, and optimization strategies for CPU, AI accelerator, and SoC blocks.
- Develop and maintain architectural, activity-based, RTL, gate-level, emulation, and silicon power models.
- Set up and run RTL- and gate-level power analysis, develop benchmarks and tests, and review results for opportunities at the architecture, RTL, synthesis, and implementation levels.
- Characterize CPU, memory, PCIe, networking, storage, AI training, and AI inference workloads to identify power and performance bottlenecks.
- Drive power/performance/area/thermal tradeoff studies and power convergence across design & implementation phases.
- Correlate pre-silicon estimates with silicon measurements, investigate gaps, and improve models and methodologies.
What you'll need
- Experience in semiconductor power analysis, modeling, optimization, power management, workload characterization, or silicon validation.
- Strong understanding of CMOS power fundamentals and power-reduction techniques.
- Knowledge of CPU, AI accelerator, memory, I/O, interconnect, and processor workload behavior.
- Experience with RTL and gate-level power-analysis tools and methodologies; familiarity with tools such as Spyglass, Power Artist, Joules, PrimePower, or equivalent.
- Strong programming and scripting skills in Python.
Nice to have
- Experience with emulation, FPGA, silicon measurement, telemetry, or power/performance correlation.
- Experience with voltage-frequency characterization, AVS, silicon binning, SKU definition, or Power-management firmware.
- Scripting skills in Tcl, Perl, C/C++, shell, SQL, or data-analysis tools are helpful.
- Experience using AI for productivity in silicon design
Skills: power modeling, power analysis, power management, CPU architecture, AI accelerator, CMOS fundamentals
