Job Title: Senior Modeling Engineer

Position Overview

We are seeking a highly skilled Modeling Engineer to develop, validate, and apply advanced computational models that support the design and optimization of next‑generation sensor and system technologies. The ideal candidate combines deep theoretical knowledge with strong practical intuition and has a demonstrated ability to translate modeling insights into real‑world physical implementations. This role provides technical leadership in modeling methodologies, simulation frameworks, numerical analysis, and data interpretation. The Senior Modeling Engineer collaborates closely with cross‑functional teams to define modeling requirements, drive predictive insights, and accelerate development across complex engineering programs.

Key Responsibilities

• Develop advanced multi-physics models using ANSYS, including Electromagnetic, Static and Dynamic Structural, Fluid Flow, Atomic Flow, and Surface Kinetics simulations.
• Correlate modeling results with experimental data to ensure accuracy, reliability, and predictive capability.
• Work closely with experimental, design, and systems engineering teams to guide physical prototypes and product development.
• 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.

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.
