The position involves developing and maintaining high-accuracy FBAR/BAW device and module models for RF applications. The candidate will be responsible for building scalable and reusable modeling libraries for different product platforms, extracting model parameters from measurement data, and validating against empirical results. The role also includes automating modeling workflows to improve simulation efficiency and consistency, performing acoustic and electrical simulations to predict device performance, and collaborating with design, process, and characterization teams to ensure model fidelity. Additionally, the candidate will support design teams with model integration and tuning during new product development, analyze performance deviations, and provide feedback for design or process optimization. Documentation of modeling methodologies, assumptions, and validation procedures is also required, along with staying current on modeling techniques and contributing to internal knowledge sharing.
