Senior Multiphysics Simulation Engineer

Synopsys Inc; Austin (TX); On-site; USD 110,000 - 160,000; Full time

Job summary

Synopsys Inc is seeking a hands-on Mechanical/Materials science engineer to advance Multiphysics simulations for thermal, structural, and reliability analyses of advanced ICs. You will design, implement, and optimize features in a distributed solver, collaborating with leads to refine requirements and deliver robust software on schedule.

You will work with FEM/FVM modeling, C++ and Python in large codebases, translating physics into scalable code while maintaining sign-off accuracy.

Qualifications

• BS in Mechanical Engineering, Materials Science, or related field.
• Strong FEM and FVM knowledge.
• Thermodynamics and heat transfer theory understanding.
• Experience with large, complex codebases.
• Proficient in C++ and Python scripting.

Responsibilities

• Design, develop, and deliver new capabilities for Synopsys Multiphysics simulation tools for thermal, structural, and reliability analysis of complex ICs including 3DIC, FinFET, and stacked-die architectures.
• Work with your manager and technical leads to refine requirements and then execute.
• Diagnose and fix software defects across the codebase, ensuring correctness and maintaining the sign-off accuracy.
• Optimize solver performance and memory usage so that engineers can run larger, more complex simulations faster.
• Build unit, regression, and system-level tests to validate new features and ensure changes do not break existing workflows.
• Collaborate with other engineers, technical leads, and your manager to communicate design decisions, surface dependencies, and refine solutions as the code evolves.
• Apply best practices in software engineering to ensure your code is efficient, scalable, maintainable, extensible, and understandable by the team.
