Senior Design Engineer – Piezoelectric Transducer Systems (Industrial)

Crane Company•Billerica, MA

About The Position

As a Senior Design Engineer, you will be responsible for leading the design and development of piezoelectric transducer assemblies and optimizing their performance across acoustic, mechanical, and electrical domains in challenging and variable clamp-on and wetted configurations. You will build and validate coupled multi-physics models using tools like COMSOL or OnScale, validating simulation results with experimental data and refining them accordingly. You will develop detailed designs and production documentation to meet hazardous area requirements and environmental constraints using SolidWorks, and support the creation of thorough and concise assembly and test process documentation for global production teams in SAP. You will design and execute experimental validation test plans for prototype builds to ensure performance, reliability, and environmental robustness, and own the root cause analysis to diagnose and resolve performance gaps. You will serve as a technical lead or subject matter expert in piezoelectric transducer design by mentoring junior and cross-functional engineers, contributing to design reviews and engineering standards, and influencing technology direction and best practices across the organization.

Requirements

BS/MS in Mechanical Engineering, Applied Physics, or related field
5–10 years of relevant experience in transducer, ultrasonics, or precision electromechanical systems
