Senior Physical Design Engineer, Annapurna Labs (AWS)
KGSJob Title
Senior Physical Design Engineer, Annapurna Labs (AWS)
Role Summary
Join the Cloud-Scale Machine Learning Acceleration team to design and optimize custom SoCs used in AWS ML servers (Inferentia, Trainium). The role focuses on physical implementation, sign-off, and methodology development to deliver high-quality silicon at scale.
Experience Level
Senior — typically 6+ years of ASIC physical design experience (RTL-to-GDSII).
Responsibilities
The engineer will own physical implementation tasks and collaborate with RTL, architecture, and verification teams to achieve design closure.
- Drive architectural feasibility studies and power-performance-area tradeoff analysis with RTL/logic teams.
- Implement IO/core subsystems and blocks: synthesis, floorplanning, pin/bus planning, place & route, power/clock distribution.
- Perform congestion analysis, timing closure, IR drop analysis, physical verification, ECOs, and sign-off.
- Develop and improve physical design methodologies and implementation flows.
- Evaluate third-party IP, specify physical-domain requirements, and integrate IP into designs.
- Collaborate across teams and mentor junior physical designers as needed.
Requirements
Must-have technical skills and domain experience.
- Proficient scripting experience with Python, Perl, Bash, or PowerShell.
- 6+ years of hands-on ASIC physical design experience (RTL-to-GDSII) using commercial EDA tools.
- Practical experience with synthesis, equivalency verification, floor planning, pin/bus planning, P&R, power/clock distribution, congestion analysis, timing closure, IR drop analysis, physical verification, and ECOs.
- Deep understanding of sign-off activities: timing, IR/EM, and physical verification.
- Experience evaluating and integrating 3rd-party IP and driving IP requirements in the physical domain.
Nice-to-have / Preferred:
- Experience mentoring or leading junior engineers.
- Proven ability to develop CAD flows and automation for synthesis, P&R, and verification tasks.
- Knowledge of device physics, custom/semi-custom implementation, and system interfaces (DDR, PCIe, fabrics).
- Experience extracting QOR metrics and analyzing design parameter trends.
Education Requirements
Specified: BS with 8+ years relevant experience, or MS with 6+ years in Electrical Engineering or Computer Science. No other degrees or certifications were specified.
