Role Overview

This role owns power architecture, estimation, optimization, and verification across Positron’s AI accelerator roadmap. You will define power methodology from architectural modeling through silicon validation, ensuring industry-leading performance-per-watt while meeting aggressive power and thermal constraints.

Key Responsibilities

Power Architecture & Strategy

• Own the overall chip power strategy, defining approaches for dynamic power, leakage, clock power, memory power, interconnect power, SerDes power, idle power, and peak power.

Power Modeling

• Develop accurate power models across the full development lifecycle, from early architectural estimation through RTL and gate-level estimation.
• Perform vector-based and activity-driven power analysis to validate estimates against real workload behavior.

Power Optimization

• Drive power optimization techniques including clock gating, operand isolation, power gating, voltage islands, and multi-Vt optimization.
• Apply memory, pipeline, toggle-reduction, and data-movement optimization techniques, including approaches tailored to AI workloads.

Power Integrity

• Partner with the backend team on IR drop, electromigration (EM), power distribution, and power grid planning.
• Define power-on sequencing, power domains, reset sequencing, isolation, retention, and UPF/CPF specifications.

Power Verification

• Own power-aware simulation and UPF verification.
• Lead reset verification, low-power state validation, wakeup validation, and power sequencing verification.

Cross-Functional Collaboration

• Partner closely with Architecture, RTL, Backend, Firmware, Thermal, Packaging, and System Engineering teams to align power decisions across the full chip development flow.

AI-Enabled Engineering

• Use AI-driven tools to improve power analysis, regression triage, power anomaly detection, activity clustering, and identification of optimization opportunities.

Required Qualifications

• 12+ years of ASIC design experience.
• Deep expertise in low-power design techniques and methodologies.
• Hands-on experience with UPF/CPF power specification and verification flows.
• Expert-level proficiency with PrimePower and Joules or equivalent power analysis tools.
• Strong background working with advanced process nodes.
• A solid grasp of RTL design and its impact on chip power.
• Proven experience achieving aggressive power targets in production silicon.

Preferred Qualifications

• Experience with AI accelerator architectures.
• Familiarity with LPDDR and HBM memory interfaces.
• Working knowledge of PCIe.
• Experience with dynamic voltage and frequency scaling (DVFS).
• Exposure to thermal modeling.
• Hands-on experience with silicon power validation.

Leveling & Scope

While this role is currently posted at a specific level, we are a growth-oriented organization and are open to hiring at a more senior level for the right candidate.
