Job summary

Ampere is a semiconductor design company delivering high-performance energy-efficient AI compute. We are seeking a Principal Power Architect to lead power modeling, analysis, optimization, and validation across CPU, AI accelerator, memory, and interconnect blocks.

The role spans architecture, RTL, firmware, and silicon, requiring a strong CMOS foundation and the ability to turn workloads and power data into actionable design decisions. A focus on pre-/post-silicon power activities is expected.

Qualifications

• Experience in semiconductor power analysis, modeling, optimization, power management, workload characterization, or silicon validation.
• Strong CMOS 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 Spyglass, Power Artist, Joules, PrimePower is useful.
• Experience with emulation, FPGA, silicon measurement, telemetry, or power/performance correlation is valuable.

Responsibilities

• 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.
• Develop automation, data-processing flows, dashboards, and analysis scripts using Python, TCL, Perl, or similar languages.
• Use AI for productivity to accelerate workload characterization, power modeling, anomaly detection, regression analysis, test generation, documentation, and power-management decisions.
