Job summary

Subsense is building a non-surgical, bidirectional brain–computer interface and seeks an electronics engineer to design drive, interface, and power electronics for medical-device systems. You’ll translate experimental requirements into electrical specifications and develop mixed-signal circuits for prototypes, collaborating with neuroscience, mechanical engineering, and software teams.

The role emphasizes hands-on hardware development, from schematic to bring-up, with a focus on reliability,

Qualifications

• Master’s degree in electrical engineering, biomedical engineering with a strong electronics focus, or equivalent practical experience.
• Hands-on experience developing electronics for medical devices, neurotechnology, instrumentation, or related experimental hardware systems; ultrasound systems is a plus.
• Strong grounding in analog and mixed-signal design, power electronics, signal integrity, grounding, and noise reduction.
• Experience designing drive, interface, or impedance-matching circuits for transducers, actuators, sensors, or other electrically driven hardware, with an understanding of how electrical loading affects system performance.
• Ability to take a PCB from schematic through bring-up and systematic troubleshooting.
• Proficiency with oscilloscopes, signal generators, and relevant impedance, network, or spectrum measurement equipment.
• Experience using Python, MATLAB, or similar tools for instrument control, data analysis, and test automation.
• Ability to translate ambiguous requirements into practical experiments and clearly communicate findings across engineering and scientific teams.

Responsibilities

• Design drive, control, and interface electronics for neurotechnology and medical-device systems, including waveform generation, power amplification, impedance matching, sensing, and transducer interfaces.
• Develop analog, digital, and mixed-signal circuits, owning schematic capture, PCB layout collaboration, board bring-up, and debugging.
• Translate application and experimental requirements into electrical specifications, including operating frequency, output power, timing, duty cycle, channel synchronization, and sensing requirements.
• Integrate transducers or other stimulation/sensing hardware, power supplies, embedded controllers, sensors, and software into working prototypes.
• Build automated test setups to characterize electrical performance, transducer loading, efficiency, thermal behavior, and repeatability.
• Partner with acoustics specialists to correlate electrical measurements with acoustic output and identify causes of performance variation.
• Implement monitoring, fault detection, interlocks, and protective circuitry appropriate to the device’s intended use.
• Document design decisions, test methods, and verification results; contribute to risk analysis and design reviews.
• Work with suppliers and manufacturing partners to improve component selection, assembly, testability, and reliability.
