Job summary

Positron Corporation is seeking a senior Physical Design lead to own end-to-end implementation for AI accelerator designs, from floorplanning through tapeout. You will drive timing, power closure, and signoff quality, partnering with RTL, synthesis, DFT, packaging, and backend teams.

The role requires 12+ years in physical design, advanced-node tapeout experience, and hands-on mastery of Innovus and ICC2, along with expertise in signoff metrics.

Qualifications

• 12+ years of experience in physical design, spanning floorplanning through tapeout.
• Proven track record across multiple advanced-node tapeouts.
• Expert-level proficiency in Innovus and ICC2 implementation flows.
• Deep expertise in physical implementation, including floorplanning, clock tree synthesis, timing, and power closure.
• Hands-on experience driving full signoff across timing, power, and related quality metrics.

Responsibilities

• Own floorplanning, macro placement, and power planning across Positron’s AI accelerator designs.
• Drive clock tree synthesis, place and route, and routing optimization through to timing closure.
• Own signal integrity, IR/EM closure, ECO implementation, and metal fill to deliver signoff-quality results.
• Own tapeout signoff for all physical implementation deliverables.
• Develop methodology for power grids, power/ground tiles, and bump planning.
• Build congestion analysis and wire estimation approaches to support early floorplan decisions.
• Define partitioning and hierarchical implementation strategies for complex designs.
• Own Innovus-based implementation flows end to end.
• Apply hands-on expertise across Innovus, ICC2, Tempus, PrimeTime, Voltus, RedHawk, and Calibre.
• Drive closure across timing, power, area, congestion, DRC, LVS, EM, IR, and yield.
• Partner with backend design services to align on implementation strategy and execution.
• Review implementation quality and lead reviews across the team.
• Apply AI-enabled techniques for QoR analysis, congestion prediction, routing prediction, and floorplan optimization.
