Sr Physical Design Engineer (GF 12LP) – 100% remote
Full-time: Salary + Benefits + Bonuses / Contractor
Work Status: US Citizen required.
Location: Remote, anywhere in USA

About the Role
We are seeking a Senior Physical Design Engineer to lead the RTL-to-GDSII implementation of high-performance SoCs. In this role, you will take ownership of advanced FinFET design challenges, push Power, Performance, and Area (PPA) boundaries, and drive robust timing closure targeting the GlobalFoundries 12LP node.
What Youll Do

- End-to-End Implementation: Drive block- and top-level physical design from synthesis through GDSII signoff using the Synopsys Fusion Design Platform.

- Core P&R & Optimization: Execute floorplanning, power grid design, placement, Clock Tree Synthesis (CTS), and detail routing optimized for GF 12LP standard cell architectures.

- Timing & Signoff: Lead Static Timing Analysis (STA), parasitic extraction, and multi-corner/multi-mode closure using PrimeTime and StarRC.

- Physical Verification & Reliability: Resolve advanced FinFET physical challenges, including double patterning, DRC/LVS (ICV), and EM/IR-drop analysis (RedHawk).

- Automation: Develop Tcl and Python scripts to streamline flows, improve runtimes, and track PPA metrics.

What You Bring

- Experience: 5+ years of ASIC physical design experience with proven tape-outs on advanced FinFET nodes (14nm/12nm).

- Tool Expertise: Deep hands-on proficiency with Synopsys Fusion Compiler (or ICC II) and PrimeTime .

- Technical Mastery: Strong grounding in synthesis, CTS, complex SDC constraints, and signoff methodologies.

- Scripting: Solid scripting skills in Tcl, Python, or Perl.

- Education: BS or MS in Electrical Engineering, Computer Engineering, or a related field.

Nice-to-Haves

- Direct tape-out experience on GF 12LP / 12LP+ .

- Deep knowledge of advanced low-power flows (UPF, multi-voltage, DVFS).

- Experience hardening high-frequency processor cores (e.g., ARM, RISC-V)

The anticipated annual base salary for this position is between $135,000 to $165,000, which also includes a comprehensive benefits package.

Full-Time Benefits:
15 days of PTO per calendar year
10 paid Holidays per calendar year
Comprehensive Medical Benefits: Company covers 80% of premiums for Employee and Dependents
Dental & Vision: Company covers 50% of premiums for Employee and Dependents
Voluntary Benefits: Life Insurance, FSA (Health and Dependent, Limited Purpose), HAS, and Gap Insurance
Employee Assistant Program (EAP)
