DPU Power Architect, Infrastructure Silicon

Meta•Austin, TX

23h•$178,000 - $250,000

About The Position

Meta's Infrastructure Silicon organization designs custom silicon that powers our data center infrastructure — SmartNICs/IPUs/DPUs, AI accelerators, and networking ASICs. We are seeking an experienced Power Architect to drive power modeling, analysis, and architectural power optimization of our Data Processing Unit (DPU) designs. In this role you will influence architecture and microarchitecture decisions from early path-finding through RTL/gate-level power analysis and silicon correlation, ensuring our DPUs deliver leading performance-per-watt on real data center workloads.

Requirements

Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience
Experience in workload analysis and characterization, and abstracting power-relevant behaviors into models for architectural analysis
Experience building system-level power models and power rollups, and tracking them from early estimates through RTL/gate-level power
Experience defining or evaluating architectural power-saving features such as DVFS, power gating, and clock gating
Understanding of SoC pipelines and how data movement impacts power versus performance
Proficiency in programming languages for model development and automation (e.g., Python, C/C++, SystemC)
Experience driving analysis independently and influencing architectural direction through data

Nice To Haves

PhD in Computer Science, Computer Engineering or Electrical Engineering
15+ years of relevant industry experience in power architecture and power modeling for high-performance SoCs
Experience with power management firmware/software co-design, on-die power telemetry, and closed-loop power/thermal control
Experience with simulation/emulation environments used in ASIC development flows, including emulation-based activity capture (FSDB/SAIF) for long-window power analysis
Experience with low-power implementation flows, including multi-voltage/UPF power intent, retention and isolation strategies
Experience building or scaling power modeling and power regression infrastructure for hyperscale data center ASICs (network, storage, or AI accelerator designs)
Familiarity with post-silicon power measurement, telemetry, and model-to-hardware correlation methodologies
Experience with industry-standard power estimation and sign-off tools (e.g., Synopsys PrimePower/PTPX, Cadence Joules, Ansys PowerArtist) for power analysis and optimization
Familiarity with power delivery network, voltage droop/di-dt analysis, and rack/platform-level power and thermal constraints

Responsibilities

Analyze and characterize real-world DPU software use cases (network virtualization, storage offload, crypto/compression, packet processing) to identify hardware power bottlenecks and power-relevant behaviors
Build and maintain workload-driven, system-level power models and power rollups for current and future SmartNIC/IPU/DPU architectures, tracking accuracy from early analytical estimates through RTL and gate-level power analysis
Quantify architectural and micro-architectural trade-offs with respect to PPA, with emphasis on energy-per-transaction, power-per-bit moved, and performance-per-watt, to inform and guide design decisions
Define and drive structural power-saving architecture features, including DVFS, AVS, power gating, clock gating, activity throttling, power state management, and workload-aware power policies
Analyze SoC pipelines and data movement paths (host-to-DPU, memory/fabric/network traffic) to understand and optimize the power-versus-performance trade-off
Own power budgets and provide power-delivery and thermal inputs in partnership with design, physical design, firmware, platform, and software teams
Correlate pre-silicon power projections with post-silicon measurements and drive methodology improvements based on findings
