Full Job Description
Physical Design Engineer (ASIC/SoC) - Onsite
Clearance Requirement: Active Secret Clearance (or ability to obtain and maintain one)
Own the physical implementation of complex, high-performance, and low-power designs from netlist through GDSII tape-out. Working alongside a collaborative team of digital design, verification, and systems engineers, you will leverage industry-leading EDA tools to ensure our silicon meets the rigorous performance, power, and area (PPA) targets required for national security applications.
Key Responsibilities
  • Netlist-to-GDSII Execution: Drive block-level and chip-level physical implementation, including floorplanning, power grid design, placement, clock tree synthesis (CTS), and routing using Synopsys Fusion Compiler.
  • Timing Closure: Perform rigorous Static Timing Analysis (STA), constraint validation, and timing closure using Synopsys PrimeTime across multiple corners and operating modes.
  • Power & Reliability Analysis: Conduct dynamic and static IR-drop analysis, as well as Electromigration (EM) checks, using Ansys Redhawk to ensure robust power delivery and design reliability.
  • Physical Verification: Execute and debug Design Rule Checks (DRC) and Layout Versus Schematic (LVS) checks to ensure manufacturing compliance and flawless tape-outs.
  • Methodology Improvement: Collaborate with cross-functional teams to refine physical design methodologies, automate repetitive workflows using Tcl/Python, and optimize the overall PPA.
Required Qualifications
  • Clearance: Must be a U.S. Citizen with an Active U.S. Secret Clearance (or the ability to obtain and maintain one).
  • Education: Bachelor's or master's degree in electrical engineering, Computer Engineering, or a related field.
  • Experience: Proven industry experience in ASIC/SoC physical design and tape-out cycles.
  • Tool Proficiency: Hands-on expertise with Fusion Compiler (or equivalent place-and-route tools like IC Compiler II/Innovus).
    • Deep knowledge of STA and sign-off timing closure using PrimeTime.
    • Experience with EM/IR analysis using Redhawk.
    • Proficiency in physical verification (DRC/LVS) sign-off tools (e.g., Calibre, IC Validator).
  • Scripting: Strong scripting skills in Tcl, Python, or Perl to automate EDA flows.
Problem Solving: Exceptional analytical skills and the ability to debug complex layout, timing, or integration issues autonomously.

The anticipated annual base salary for this position is between $170,000 to $210,000, 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)
• 401k - Traditional & Roth
• Life/AD&D and Long-Term Disability
• Tuition reimbursement
