Original job description

Senior Principal Physical Implementation Engineer

Job Description:

We are seeking an experienced Physical Design / P&R Engineer to take a key role in delivering complex, high-performance ASICs from RTL/netlist through GDSII and tapeout. You’ll own critical aspects of physical implementation, including floorplanning, placement, CTS, routing, timing closure, and PPA optimization, working with advanced technologies such as RISC-V, DDR, and SerDes. Using industry-leading tools including Synopsys Fusion Compiler and Siemens Calibre, you’ll solve challenging physical design problems and help drive successful silicon outcomes. This is an opportunity to make a significant technical impact while collaborating with a highly experienced, multidisciplinary ASIC engineering team.

Essential Duties and Qualifications:

Analyze and optimize designs to meet power, performance, and area (PPA) objectives while satisfying timing, signal integrity, reliability, and manufacturability requirements.
Collaborate closely with RTL design, verification, DFT, analog/mixed-signal, packaging, and other engineering teams to ensure successful chip integration.
Develop and optimize floorplans incorporating complex IP and high-speed interfaces, including DDR and SerDes.
Develop, maintain, and improve physical design flows, scripts, methodologies, and automation to increase efficiency and design quality.
Identify and resolve congestion, routing, timing, power integrity, and physical verification issues throughout the implementation process.
Participate in design reviews and provide recommendations regarding floorplanning, physical architecture, implementation strategy, and PPA tradeoffs.
Perform full-chip physical design implementation from synthesized netlist through GDSII, including floorplanning, power planning, placement, clock tree synthesis (CTS), routing, optimization, and timing closure.
Perform physical verification and signoff activities using Siemens Calibre, including DRC and LVS verification and resolution of physical design violations.
Perform static timing analysis and drive timing closure across multiple operating modes, process corners, and design constraints.
Provide technical guidance and mentoring to other engineers and contribute to the continued development of the team's internal physical design capabilities.
Support final design signoff and tapeout, ensuring all applicable physical design and verification requirements have been satisfied.
Support integration and physical implementation of third-party and internally developed IP blocks.
Support the physical implementation and integration of RISC-V processor-based designs and subsystems, including timing, power, and physical design considerations.
Troubleshoot complex implementation and signoff issues and drive corrective actions through resolution.
Utilize Synopsys Fusion Compiler for physical implementation, optimization, and design closure.

Qualifications:

10+ years of direct industry experience with ASIC and/or SoC design.
BSEE/MSEE or equivalent
Excellent problem-solving skills and attention to detail.
Experience with industry standard development tools and methodologies.
Familiarity with RISC architectures (e.g., ARM, MIPS).
Proficiency in Synopsys Design Compiler and other EDA tools.
Proven track record of first-pass successes.
Self-starter with the ability to assume leadership roles.
Strong background in RTL based digital IC design using Verilog/SystemVerilog
Strong understanding of digital design principles.
Willingness to mentor and develop less experienced engineers.
