Job summary

Google in Sunnyvale, CA seeks a senior ASIC verification engineer focused on post-layout low-power signoff and TPU architecture to shape AI/ML hardware acceleration.

You will validate UPF, work with Synopsys VCLP, Innovus and Fusion, and drive multi-Voltage design signoff from synthesis to place and route.

The role offers equity and a 15% target bonus, with opportunities to impact Google's next generation TPU systems.

Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, or equivalent practical experience.
• 8 years of experience in post-layout physical netlist validation and low-power signoff in advanced ASIC design workflows.
• Experience with static low-power rule-checking tools (VCLP/CLP) and debugging structural checks and signal corruption issues.
• Experience validating isolation cells, power switches, level shifters, retention registers, and always-on cells across synthesis to place-and-route.

Responsibilities

• Design, deploy, and carry out post-layout low power verification methodologies per tapeout signoff criteria.
• Validate multi-voltage design collateral with gate-level checks to ensure power/ground integrity and UPF alignment.
• Drive resolution of Physical Design and Place & Route anomalies, mitigating wrong-domain buffering and isolation issues.
• Debug CTS implementations, analyze level shifter behavior and high-fanout networks, and manage multi-voltage skew.
• Refine power state tables and UPF scripts to translate Golden RTL to final physical netlist.

Job description

In most instances, this position requires in-person interviews as part of the hiring process.

Minimum qualifications:

• Bachelor's degree in Electrical Engineering, Computer Engineering, or equivalent practical experience.
• 8 years of experience performing post-layout physical netlist validation and low-power signoff within advanced ASIC design workflows.
• Experience with static low-power rule-checking tools (such as VCLP or CLP), including experience in debugging structural checks and signal corruption issues.
• Experience validating special low-power components (isolation cells, power switches, level shifters, retention registers, and always-on cells) across all stages from synthesis to place and route.

Preferred qualifications:

• Master's degree or PhD in Electrical Engineering, Computer Engineering or Computer Science, with an emphasis on computer architecture.
• Experience with scripting languages (e.g., Tcl or Python) to automate Engineering Change Orders (ECOs) and improve verification workflows.
• Experience interacting with P&R tools (Innovus, Fusion) and an understanding of standard cell timing, hierarchical construction, and physical logic optimization.
• Experience with UPF implementation, low-power architecture design, and resolving low-power check violations.
• Expertise in resolving technical issues within the IEEE 1801 UPF framework and physical gate-level netlist flow.
• Familiarity with timing-driven Place and Route, including insertion, scaling, level shifters, and always-on cells.
