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 new 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

Install the Base Career Chrome Extension and autofill job applications across major job boards with your profile.
Trusted by over 500,000 job seekers on Base Career
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 collaborative startup environment
We Encourage Diverse Perspectives
We believe that varied backgrounds, experiences, and perspectives help us solve complex problems, and recognize that expertise and potential are not always captured by a job description, so if you can help drive our mission forward, we encourage you to apply!
