Senior/Staff MEMS Development Engineer will be responsible for development of MEMS ultrasound sensors integral to TDK products. Candidate will be responsible for modeling, characterization, and validation of core technology used in next-generation ultrasound-based imagers. The role is interdisciplinary and the candidate will interface with cross-functional teams during development of new sensors. The candidate should possess strong engineering background in ultrasound transducers (e.g. PMUT, CMUT, piezoelectric transducers, or other comparable physical sensors) and transducer arrays. This position requires in-depth knowledge of MEMS, acoustic, and system level modeling and validation techniques. Job responsibilities may include but not limited to:
1. Responsible for the validation and characterization of prototype MEMS ultrasound sensor designs
2. Development and debug of complex innovative electronic hardware to support device validation and characterization
3. Design and implement of experiments to evaluate sensor performance and reliability using electrical, mechanical and acoustic experimental techniques to ensure device meets product requirements.
4. Development and debug of complex innovative software to support data collection and device evaluation
5. Validate and debug MEMS designs to ensure successful product release and feedback into design know-how and next-generation development.
6. Develop new FEA / system-level behavioral models to predict physical behavior of piezoelectric ultrasound transducer arrays and product performance.

Required Skills and Qualifications:
• Ph.D. ME, Ph.D. AA, Ph.D. EE, or other equivalent
• In-depth knowledge of fundamental principles and modeling of MEMS acoustic and/or piezoelectric MEMS sensors, (e.g. CMUT, PMUT, or similar devices).
• Hands-on knowledge of ultrasound sensor characterization techniques (e.g. pulse-echo, impedance measurements) and standard electronic bench test equipment (oscilloscopes, spectrum/network analyzers, signal generators, Laser Doppler Vibrometer (LDV), etc.)
• Hands-on experience with software development for instrument control and data analysis (e.g. using Matlab, Python, C#, etc).
• Solid understanding of time-domain and frequency-response characterization methods
• Hands-on knowledge of MEMS fabrication techniques and limitations.
• Working knowledge of analog circuits
• Ability to communicate ideas clearly and concisely
• Problem solving skills to develop creative technical solutions

Desired Skills:
• Proficiency with FEA simulation of MEMS ultrasound transducers (e.g. COMSOL, ANSYS, PZFlex,  PiezoCAD etc.) a plus.  
• Understanding of MEMS / semiconductor packaging
• Familiar with reliability testing methodology
