MEMS Design Engineer


Who We Are:

Sonus Microsystems is developing a novel type of MEMS sensor that can disrupt healthcare diagnosis and industrial testing. Our proprietary technology involves fabrication of polymer-based Capacitive Micromachined Ultrasound Transducers (polyCMUTs), which have unique characteristics that enables the use of ultrasound in applications not previously possible with piezoelectric or silicon-based transducers. Our technology has applications in multiple markets, including healthcare, non-destructive testing and consumer electronics products.


Who You Are:

We are seeking highly technical and motivated engineers or scientists with entrepreneurial mindset, passion for impactful work and strong MEMS background to join our growing team.

In this role you will be responsible for the design, development, optimization, and manufacturing of novel MEMS-based ultrasound transducers using polymer materials.


•  Support the product development of various MEMS-based ultrasound transducers, including design/simulation and process development

•  Handle MEMS design software such as L-edit, KLayout, Clewin or similar

•  Improve designs of transducers using analytical and FEM models

•  Read and analyze scientific articles and patents

•  Identifying patentable ideas and design improvements.

•  Conduct basic microfabrication activities, including:

-  Spin coating of photoresist, baking, and development

-  UV exposure in mask-aligners or maskless lithography systems

-  PVD tools (e.g., e-beam evaporation, sputtering systems)

-  Usage of inspection tools like profilometers and interferometers

•  Perform electromechanical and acoustic characterization activities, including:

-  Electrical tests (using impedance analyzers, vector network analyzers, etc)

-  Vibration characterization (using laser Doppler vibrometer)

•  Data analysis and signal processing using MATLAB or Octave

•  Maintain detailed records of experiments.

•  Prepare reports and technical presentations.

•  Customer interaction, requirement gathering and architecting novel solutions for partners.

•  Regular interaction with materials and service suppliers

•  Collaborate with a diverse team of technicians, engineers, scientists and executives.
