Job Description

Job Summary

As a Senior Design Engineer, you will be responsible for:

Leading the design, and development of piezoelectric transducer assemblies and optimization of their performance across acoustic, mechanical, and electrical domains in challenging and variable clamp-on and wetted configurations.

Building and validating coupled multi-physics models using tools like COMSOL or OnScale, validating simulation results with experimental data and refining them accordingly.

Developing detailed designs and production documentation to meet hazardous area requirements and environmental constraints using SolidWorks, and supporting the creation of thorough and concise assembly and test process documentation for global production teams in SAP

Designing and executing experimental validation test plans for prototype builds to ensure performance, reliability, and environmental robustness, and owning the root cause analysis to diagnose and resolve performance gaps.

Serving 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

What We're Looking For:

To be successful in this role you will have:

BS/MS in Mechanical Engineering, Applied Physics, or related field

5-10 years of relevant experience in transducer, ultrasonics, or precision electromechanical systems

Strong background in multi-physics modeling (COMSOL, OnScale, or similar) and comfortable discussing modelling assumptions, and how material variation and installation conditions impact real-world transducer performance.

Hands-on experience with the installation of PZT-based transducers, correlating simulation results with hardware testing and making design decisions based on observed discrepancies

Proficiency in SolidWorks for mechanical design and documentation

Experience moving designs from concept through commercialization and production

Strong understanding of:

Acoustic wave propagation

Mechanical dynamics and vibration

Bonding, packaging, and assembly methods

Ability to work effectively across engineering, manufacturing, and product teams

Strong Candidates will also have:

Experience with flow measurement systems, ultrasonics, or industrial instrumentation

Familiarity with hazardous area (e.g., ATEX, IECEx) design constraints

Experience designing products for harsh environments

Experience with acoustic coupling challenges in pipe-mounted or clamp-on transducer systems

Background in system-level performance optimization

Experience working with external piezo suppliers and specifying transducer element requirements

Prior experience in a lead or technical ownership role
