Senior Staff Engineer, Multiphysics

Job Title

Senior Staff Engineer, Multiphysics

Role Summary

Customer-facing engineering role to integrate multiphysics simulation into Synopsys signoff flows for advanced packaging, 3DIC, HBM, and chiplet designs. The role works with Korean semiconductor customers and global R&D to enable production adoption of unified electrical, thermal, mechanical, and EM-aware signoff flows.

Experience Level

Senior — typically 8+ years of relevant hands-on experience in multiphysics simulation, semiconductor signoff, or advanced packaging and 3DIC design.

Responsibilities

Provide customer enablement, build production flows, and translate production issues into actionable R&D priorities.

• Deploy and enable RedHawk-SC, RedHawk-SC ET, Totem-SC, HFSS, and HFSS-PI at Korean semiconductor and foundry customers.
• Build and validate end-to-end flows integrating Synopsys EDA tools (Fusion Compiler, StarRC, PrimeTime, PrimePower) with Ansys multiphysics platforms for electrical, thermal, mechanical, and EM co-analysis.
• Provide hands-on technical support for advanced packaging, 3DIC, HBM5, and chiplet interconnect designs to solve tapeout challenges.
• Develop production-grade reference flows and benchmarks that improve turnaround time, accuracy, and design closure efficiency.
• Translate customer requirements and production roadblocks into prioritized R&D feedback and roadmap items.
• Automate workflows and tool integration using Tcl and Python.
• Represent the company in technical reviews, proof-of-concept engagements, and customer-facing presentations in Korean and English.

Requirements

Technical must-haves for successful performance in this role. Degree and formal education expectations are listed under Education Requirements.

Must-have:

• Proven hands-on experience with multiphysics simulation and semiconductor signoff (EM, thermal, mechanical, fluid, or coupled-domain; IR-drop, electromigration, SI/PI, thermal analysis).
• Production or customer-facing experience with tools such as Ansys HFSS, RedHawk-SC (including RedHawk-SC ET), Icepak, Fluent, or equivalent.
• Strong understanding of physical design and signoff flows and how analysis results affect tapeout decisions.
• Proficiency in Tcl and Python for automation and tool integration.
• Fluency in Korean and English and ability to present technical results to customers and global teams.
• Experience working independently at customer sites and coordinating with global R&D teams; strong diagnostic and problem-solving skills.

Nice-to-have:

• Experience with GPU-accelerated simulation, AI-driven optimization, or chiplet interconnect standards such as UCIe.
• Familiarity integrating Synopsys EDA tools (Fusion Compiler, StarRC, PrimeTime, PrimePower) with multiphysics platforms for end-to-end signoff.

Education Requirements

MS or PhD in Electrical Engineering, Mechanical Engineering, Applied Physics, Computational Science, or a related field; or a Bachelor's degree with equivalent industry depth or equivalent practical experience.
