About the role

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.

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.

Requirements

• 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.

Benefits

• Most locations offer a 9/80 schedule, providing every other Friday off.
• Competitive compensation & 401(k) program to plan for your future.
• Robust medical, dental, vision, & disability coverage with qualified wellness discounts.
• Basic Life Insurance and Additional Life & AD&D Insurances are available.
• Flexible Vacation & PTO.
• Paid Parental Leave.
• Generous Employee Referral Program.
• Voluntary Benefits Available: Longer Term Care, Legal, Identity Theft, Pet Insurance, and more.
• Voluntary Tricare Supplement available for military retirees.
