Senior Multiphysics Simulation Engineer

Ansys, Inc.; Austin (TX); On-site; USD 101,000 - 151,000; Full time

Job summary

Synopsys Multiphysics simulation and modeling tools seek a highly skilled engineer to design, develop, and improve capabilities for thermal, structural, and reliability analysis of advanced ICs. You will work with leads to refine requirements, implement features, and ensure correctness across evolving codebases.

The role requires strong FEM/FVM knowledge, thermodynamics expertise, and proficiency in C++ with Python scripting.

Qualifications

• BS in Mechanical Engineering, Materials Science, or related field with 3+ years of relevant experience, or MS in Mechanical Engineering, Materials Science, or related field (will consider PhD).
• Strong knowledge of finite element method (FEM) and finite volume method (FVM) modeling
• Deep understanding of thermodynamics and heat transfer theory
• Knowledge in mechanics of materials, solid mechanics, stress analysis, and fatigue analysis
• Proficient in C++ with a broad understanding of the language and ability to work in large, complex codebases. Python scripting, automation and prototyping, a plus.
• Working knowledge of data structures, algorithms, and debugging techniques
• Knowledge using APDL, Ansys Mechanical, Abaqus, Ansys Icepak, Ansys Fluent, or COMSOL is a big plus

Responsibilities

• Design, develop, and deliver new capabilities for Synopsys Multiphysics simulation and modeling tools used for thermal, structural, 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
