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 recent 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 Design

Design, model, and prototype circuits for driving and receiving signals from ultrasound transducers

Develop low-noise, high-sensitivity front-end circuits to interface with CMUT/polyCMUT elements

Create pulse generation circuitry, biasing systems, and impedance matching networks

Simulate designs using SPICE tools and iterate based on measured results





Support development of macromodels or behavioral models (e.g., Verilog-A) for system-level simulation

Embedded Systems and Software Development

Integrate microcontrollers, DSPs, or FPGAs with analog circuitry for system control and data acquisition

Develop firmware or embedded code to support excitation, timing control, communication, and data handling

Write supporting software scripts for testing, automation, and data analysis (Python, MATLAB, or similar)

System-Level Electronics Development

Participate in design of RF or high-frequency signal paths for ultrasound systems

Conduct interference and noise analysis, proposing improvements for robustness and signal quality

PCB Design and Prototyping

Design multi-layer PCBs for mixed-signal systems with attention to proper grounding, isolation, and trace routing

Collaborate with vendors for fabrication and assembly

Test and validate prototypes, documenting results and recommending design iterations

Research and Documentation

Work closely with microfabrication engineers, MEMS designers, software developers, and test engineers to create integrated solutions

Review scientific literature, emerging ASIC technologies, and patents relevant to ultrasound electronics

Contribute to technical reports, presentations, and documentation for internal and MITACS reporting

Qualifications:
Required





PhD in Electrical Engineering, Mechatronics, Physics, or related field

Hands-on experience with analog/mixed-signal design, including op-amps, filters, bias circuits, and sensor interfaces

Proficiency with SPICE-based simulators (e.g., LTspice, Cadence, ADS)

Experience with embedded systems (microcontrollers, FPGAs, DSPs) and associated firmware development

Strong programming skills (Python, C/C++, MATLAB, or similar)

Experience building and testing electronic prototypes, including use of oscilloscopes, network analyzers, and similar equipment

Excellent documentation and communication skills

Ability to work collaboratively within an interdisciplinary R&D; environment

Preferred (Asset but not required)

Experience with ASIC design flows, RTL, Verilog/VHDL, or mixed-signal ASIC architectures

Background in ultrasound electronics, medical device design, or high-frequency instrumentation

Familiarity with CMUT technologies or MEMS-based sensors

PCB design experience in Altium, Cadence, or KiCad

Experience implementing signal processing algorithms in embedded or PC environments

Exposure to ultrasound imaging concepts such as beamforming or high-voltage pulsers

Working environment:

You will work across Sonus’ facilities and partner university labs, collaborating with MEMS process engineers, acoustic engineers, fabrication teams, and software developers

The role involves both deep technical design work and rapid prototyping in a fast-paced and highly cooperative startup environment
