Sr. Manager, Physical Design Engineering, Annapurna Labs

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).
