Physical Design Engineer

ABOUT

THE ROLE

We are seeking a highly skilled and experienced Physical Design Engineer to join our team. The ideal candidate will have a strong background in physical design methodologies for both SOC level and block level, including floor planning, hard IP integration, power distribution, multi‑supply, multi‑Vt, clock tree synthesis, timing budgeting, optimization and timing closure of high‑speed designs.

Experience with deep technology nodes such as 5nm/4nm is highly valued.

ESSENTIAL DUTIES AND RESPONSIBILITIES

• Develop and implement high‑performance, low‑power, area‑efficient physical design for SOC and block level designs using industry standard EDA tools.

• Work closely with digital and analog design teams to understand design requirements and constraints to implement physical design.

• Contribute to physical design flow development.

• Resolve or find workarounds for tool issues, independently or working with EDA tool vendors.

• Work closely with synthesis team to help provide feedback on design feasibility, constraints, timing, power, placement and routing issues.

• Perform physical verification, STA, EM & IR Drop analysis.

QUALIFICATIONS

• Bachelor's degree in Electrical or Computer Engineering (advanced degree preferred).

• Minimum of 5 years of industry experience in physical design.

• Knowledge and hands‑on experience with physical design methodologies and implementation.

• Proficiency in relevant EDA physical design and verification tools (e.g., Cadence Innovus, Tempus, Quantus, Voltus, Pegasus) and scripting languages (e.g., Tcl, Perl).

• Experience with custom IP integration.

• Strong understanding of deep technology nodes, preferably TSMC N5.

• Solid understanding of physical design and timing optimization techniques and strategies to achieve physical design and timing closure.

• Proven track record of delivering successful designs on time and meeting performance, power and area goals.

• Excellent problem‑solving skills and ability to analyze and debug complex physical design issues.

• Strong communication and collaboration skills to work effectively within cross‑functional teams.

PREFERRED QUALIFICATIONS

• Experience with complex clock tree synthesis.

• Knowledge of low‑power UPF based physical design flows.

• Knowledge of hierarchical physical design flows for large chips.

• Understanding of power‑aware optimization techniques for low‑power designs.

• Understanding of process related issues such as OCV, DFM, yield, multi‑VT strategies and thermal management.
