Electronics Design Engineer (Postdoc)
About The Position
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.
Requirements
- 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
Nice To Haves
- 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
Responsibilities
- 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
- 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)
- 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
- 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
- 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
