• Translate complex physical phenomena into clear, actionable insights for technical and non‑technical stakeholders.
• Drive the transition from theoretical models to functional hardware, ensuring model fidelity throughout development cycles.
• Document modeling approaches, assumptions, and results; present findings to cross‑functional teams and leadership.
• Conduct advanced numerical analysis using tools such as FEA, CFD, MBD, or multi-physics simulation environments.
• Mentor junior engineers in modeling best practices, numerical methods, and analysis tools.
• Evaluate new modeling tools, technologies, and techniques to continuously improve simulation capabilities.
• Communicate results and model limitations clearly to technical and non‑technical stakeholders.

Required Qualifications

• PhD in Engineering, Physics, Applied Mathematics, or a related field; or MS with 3+ years of relevant experience; or BS with 6+ years of relevant experience.
• Proven ability to relate simulation results to experimental data and physical behavior.
• Hands‑on experience in ANSYS multi-physics environments, including Electromagnetic, Structural (Static & Dynamic), Fluid Dynamics, and surface/atomic‑scale phenomena.
• Demonstrated history of moving models from concept to physical implementation.
• Strong capability in explaining and interpreting physical phenomena, both verbally and in written form.
• Excellent problem‑solving skills and a collaborative mindset.
• Experience with multi-physics modeling (thermal‑structural, fluid‑structure interaction, electromagnetic‑mechanical coupling, etc.)

Preferred Qualifications

• Experience with sensor systems, advanced materials, or semiconductor processes.
• Familiarity with scripting or automation for simulation workflows.
• Experience supporting R&D or advanced technology development programs.
• #LI-SB1
