Neurotechnology Hardware Engineer — Wearables and Biosignal Systems

The role

Design wearable instruments whose physiological signals remain measurable despite movement, interference, and practical constraints on size and power. The work is judged by characterized signal quality, not the appearance of the prototype.

The work

• Design and prototype wearable physiological sensing devices and multimodal measurement systems.
• Develop low-noise analog front ends for electrophysiological signal acquisition.
• Integrate EEG, EMG, acoustic, optical, inertial and other relevant sensing modalities.
• Design compact PCB assemblies, embedded data-acquisition systems, power management and communication interfaces.
• Evaluate noise floors, dynamic range, bandwidth, motion artifacts, signal integrity and channel synchronization.
• Work on embedded firmware, hardware timestamps, wireless streaming and sensor calibration.
• Design ergonomic mounting and mechanical integration for repeatable measurements.
• Develop standardized characterization methods and test procedures.

What matters

• Strong knowledge of analog circuit design, biosignal acquisition and embedded electronics.
• Experience with PCB design, microcontrollers and hardware debugging.
• Understanding of physiological signals, low-noise measurement and interference mitigation.
• Experience using Python or MATLAB for signal processing and characterization.
• Familiarity with wearable-device integration, mechanical CAD and prototype fabrication.

What good work looks like

A characterized wearable prototype with documented noise floor, timing, signal quality, and repeatability.

Why this work matters

Engineer sensing systems whose measurements researchers can trust.

Get in touch

Send us your CV, your personal website or examples of work you have done, particularly a wearable device or biosignal instrument you developed and tested. Include an informal handwritten statement of purpose, with no prescribed length, telling us why this mission matters to you, what difficult work has taught you, and what you would like to take responsibility for at Walnut. This mission will demand scientific rigor, patience, independent thinking and a willingness to test ideas against reality. Write the statement entirely in your own words, without using generative AI. We will not consider statements written using AI. A photograph or scan of the statement is sufficient, and a typed version is welcome if handwriting is difficult. A reference from someone who knows your work is welcome, but not required.
