Annapurna Labs, designs custom silicon powering AWS’s cloud infrastructure. Custom SoCs live at the heart of Amazon ML servers — including Inferentia and Trainium Systems — delivering high-performance ML inference and training at cloud scale. We’re looking for a Senior Manager, Physical Design Engineering to build and lead a world‑class Physical Design team delivering multi‑billion‑transistor ML accelerator SoCs on latest tech nodes. This is a player‑coach role: you will personally engage in the most critical technical decisions; chip‑level floorplan architecture, multi‑GHz timing convergence, high‑speed I/O physical design, power delivery for KW class systems, and 2.5D / 3D integrations; while building a high‑performing team and driving rigorous PPA targets, first‑pass silicon success, and relentless continuous improvement.

Key job responsibilities

• Build, hire, and develop a physical design team of 10-15 engineers. Own headcount planning, performance management, career growth, and organizational scaling to support multiple concurrent tapeouts.
• Own the physical design strategy and execution roadmap across Inferentia, Trainium, and future products: implementation architecture, hierarchical methodology, PPA target-setting, and technology node adoption.
• Institutionalize continuous PPA improvement: benchmarking frameworks, regression tracking, design-quality dashboards, post-tapeout retrospectives, and structured improvement programs that compound across generations.
• Provide hands‑on technical leadership on the hardest problems: multi‑GHz timing closure, PDN architecture, high‑speed I/O physical design, and 2.5D / 3D cross‑die integration.
• Lead technology node enablement for 2nm and beyond: PDK evaluation, reference flow development, PPA pathfinding, and adoption recommendations.
• Define and deploy innovative RTL2GDS methodologies and CAD flows. Champion AI/ML‑augmented design automation (RL‑placement, ML‑guided ECO, predictive analytics). Optimize cloud infrastructure for PD compute.
• Serve as part of senior technical interface with foundry partners and EDA vendors on tool roadmap, co‑development, and technology co‑optimization.
• Own tapeout execution: readiness reviews, foundry submittal, mask data coordination, and post‑silicon yield learning. Drive cross‑functional alignment with RTL, DFT, STA, Package, and Validation teams.

Basic Qualifications

• 5+ years people management leading PD teams of 8+ engineers, including hiring, performance management, and organizational growth.
• 10+ years hands‑on ASIC/SoC physical design across multiple advanced nodes (7nm, 5nm, 3nm) with multiple successful tapeouts.
• Technical depth across full RTL-to-GDSII: floorplanning, CTS, routing, timing closure, PDN design, IR‑drop/EM signoff, physical verification, and tapeout.
• Mastery of both EDA ecosystems: Synopsys (Fusion Compiler/ICC2, PrimeTime, StarRC, RedHawk‑SC) AND Cadence (Innovus, Tempus, Quantus, Voltus). Physical verification with Siemens Calibre (DRC, LVS, PERC).
• Deep expertise in advanced STA (MMMC, POCV/AOCV, SSTA, PBA, IR‑aware timing) and power integrity (static/dynamic IR‑drop, EM, rush current, Ldi/dt, package‑aware analysis).
• Proven expertise in high‑speed PD (multi‑GHz datapaths, SerDes, DDR5, HBM, PCIe Gen5+, UCIe) and low‑power design (UPF, power gating, DVFS, retention).
• Experience with hierarchical methodologies for very large SoCs (>1B transistors). Expert scripting in TCL, Python, Perl.

Preferred Qualifications

• Experience leading PD for AI/ML accelerators, GPUs, or high‑performance data‑center SoCs at leading semiconductor companies or hyperscalers.
• Direct 3nm GAA/Nanosheet experience; 2nm or sub‑2nm engagement. Familiarity with CFET and backside power delivery (BSPDN).
• Quantifiable track record of continuous PPA improvement and metric‑driven flow development across multiple projects and nodes.
• Strong program execution: managing concurrent tapeouts, milestone tracking, risk identification, and executive communication.
• Hands‑on 2.5D/3D integration experience (CoWoS, EMIB, InFO, SoIC, Foveros) and chiplet strategy with UCIe.
• Track record deploying AI/ML‑driven design methodologies in production flows.
• Experience with CPO, HBM4, silicon photonics, or CXL physical design.
• Multi‑foundry technology assessment experience (TSMC, Samsung, Intel Foundry Services).
• Experience managing geographically distributed teams (U.S., Israel, global).
• Experience scaling PD organizations through 2x–3x growth. Patent portfolio or industry standards contributions (UCIe, IEEE).
