Semiconductor Digital Twin & System Modeling Engineer

ASM; Phoenix (AZ); On-site; USD 120,000 - 160,000; Full time

Job summary

ASM in Phoenix, AZ seeks a candidate to join the Simulation and Collaboration Hub to develop predictive reactor and system-level models for semiconductor process tools.

You will combine dynamic system modeling with CFD, thermal and structural analysis to support equipment design, process performance and digital twin development.

The role requires hands-on modeling with MATLAB/Simulink and Simcenter Amesim, plus CFD tools, and close collaboration with design, process and controls teams.

Qualifications

• Master’s or PhD in mechanical, chemical, aerospace engineering or a related field, or a bachelor’s degree with relevant industry experience.
• Hands‑on dynamic system modeling experience using MATLAB/Simulink and Simcenter Amesim.
• Strong foundation in fluid mechanics, heat transfer, structural mechanics and numerical methods.
• Experience with CFD and thermal/structural tools such as STAR-CCM+, ANSYS Fluent/Mechanical or equivalent.
• Knowledge of system identification, parameter estimation, model validation and control fundamentals.
• Strong analytical, communication and cross‑functional collaboration skills.

Responsibilities

• Develop dynamic models of gas delivery, pressure and vacuum systems, heating systems, sensors and actuators using MATLAB/Simulink and Simcenter Amesim.
• Perform CFD, thermal and structural simulations to evaluate flow distribution, temperature uniformity and mechanical performance.
• Connect detailed physics simulations with system-level and reduced-order models to assess transient behavior and subsystem interactions.
• Design bench experiments, identify model parameters and calibrate and validate models against measured data.
• Collaborate with design, process and controls teams to recommend improvements and support control strategy development.
