[Hiring] Principal ASIC Power Engineer @Positron Corporation

Role Description

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
  • 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
  • Multi-Vt optimization
  • 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
  • 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
  • Identification of optimization opportunities

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.

What Success Looks Like

Success in this role looks like power estimates that consistently predict silicon behavior, sustained performance-per-watt leadership across Positron's product line, and a power architecture that is reused and extended across future generations of chips.
