Job Summary
Annapurna Labs designs custom silicon powering AWSs 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.
Were 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.
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.
- 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.
- 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 2x3x growth. Patent portfolio or industry standards contributions (UCIe IEEE).
