Who We Are:Sonus Microsystems is leveraging state-of-the-art and patented polymer MEMS technology to develop an affordable imaging diagnostic device aimed at transforming clinical screening and remote patient monitoring. Our proprietary technology involves fabrication of polymer-based Capacitive Micromachined Ultrasound Transducers (polyCMUTs), which have unique characteristics that enable the use of ultrasound in applications not previously possible. Our technology has applications in various markets, including healthcare, non-destructive testing, and consumer electronics products.We are expanding our R&D team through the MITACS Accelerate program and are seeking a highly skilled researcher to help us develop a current class of ultrasound transducers.Who You Are:We are looking for an electronics design engineer or scientist (master's, PhD, or postdoctoral level) with experience in analog and mixed-signal design, embedded systems, and hands-on prototyping. The ideal candidate will also bring complementary skills in software or firmware development. Experience with ASIC design flows is considered a strong asset.You will work on the electronic architecture that drives our next-generation transducers, including transmit pulsers, receive front ends, signal conditioning circuits, and embedded control.Responsibilities:Analog and Mixed-Signal Circuit DesignDesign, model, and prototype circuits for driving and receiving signals from ultrasound transducersDevelop low-noise, high-sensitivity front-end circuits to interface with CMUT/polyCMUT elementsCreate pulse generation circuitry, biasing systems,
