CRITICAL GATEKEEPER

To save everyone's time, we are only considering candidates who have personally shipped a regulated medical wearable (Class II or Class III) through FDA clearance or CE Mark approval and have hands-on experience authoring

IEC 62366

usability engineering documentation. General consumer product design, non-regulated wearables, or pure software/cloud experience will not meet the technical requirements of this clinical hardware role. Role Overview We are seeking a highly specialized Fractional Wearables Lead to own the physical patient-to-device interface for our next-generation EEG wearable patch. This role will be critical to achieving medical-grade EEG signal integrity, reliable device performance, and patient comfort during continuous, multi-day wear.

Key Responsibilities Electrode & Materials Engineering:

Lead the selection and evaluation of medical-grade adhesives and wearable materials. Characterize and optimize skin-electrode impedance stability and develop solutions to minimize motion artifacts.

Mechanical & Form Factor Design:

Design, prototype, and iterate on wearable form factors, including patch and behind-the-ear configurations, while optimizing retention, comfort, and usability across diverse skin and hair types.

Human Factors & Usability:

Lead usability engineering activities in accordance with

IEC 62366

. Design intuitive donning and doffing workflows for patients and caregivers and author usability documentation for FDA and other regulatory submissions.

Cross-Functional Collaboration:

Work closely with electrical engineering, firmware, analog front-end, clinical, and regulatory teams. Support biocompatibility testing in accordance with ISO 10993 and contribute to regulatory submissions.

Clinical Build Support:

Support the assembly and testing of our first clinical-build wearable patch and contribute to the design of early clinical studies planned for late 2026. Hard Gatekeeper Requirements Candidates must meet all of the following requirements:

Regulated Medical Wearables:

Personally shipped at least one regulated Class II or Class III medical wearable -such as a

CGM, ECG/EEG

patch, or smart hearable-that successfully achieved FDA clearance or CE Mark approval .

Hands-On Usability Engineering:

Proven experience authoring

IEC 62366

usability engineering files/documentation for an actual regulatory submission.

Electrode & Adhesive Expertise:

Deep technical expertise in skin-electrode interface physics, impedance characterization/testing, motion-artifact mitigation, and medical adhesive behavior.

Hardware Engineering Experience:

Hands-on experience with the physical design, testing, prototyping, and validation of medical wearables.

Location & Availability:

Ability to support hardware testing and collaborate with our Chicago-based engineering lab as needed. This is a hands-on engineering role, not a high-level project management position. Candidates who do not meet the hard gatekeeper requirements above will not be considered.
