Postdoctoral Electronics Design Engineer – Ultrasound Systems

About the role

Join Sonus Microsystems and the AdaMist research group at UBC to develop next‑generation ultrasound transducers. As a postdoctoral Electronics Design Engineer you will create the electronic architecture that powers high‑performance polymer CMUT devices.

Key responsibilities

• Design, model, and prototype analog and mixed‑signal circuits for driving and receiving ultrasound signals, including low‑noise front‑ends and pulse generation circuitry.
• Integrate microcontrollers, DSPs or FPGAs with analog blocks, develop firmware and embedded software for timing, control, and data acquisition.
• Design multi‑layer PCBs, manage grounding and isolation, collaborate with vendors, and validate prototypes.
• Perform RF/high‑frequency path design, interference and noise analysis, and propose robustness improvements.
• Support system‑level simulation with behavioral models (e.g., Verilog‑A) and contribute to technical reports for internal and MITACS reporting.

Required profile

• PhD in Electrical Engineering, Mechatronics, Physics or a related discipline.
• Hands‑on experience with analog/mixed‑signal circuit design, including op‑amps, filters, bias circuits and sensor interfaces.
• Proficiency with SPICE‑based simulators (LTspice, Cadence, ADS) and embedded platforms (microcontrollers, FPGAs, DSPs).
• Strong programming skills in Python, C/C++ and MATLAB.
• Experience building and testing electronic prototypes using oscilloscopes, network analyzers and related equipment.
