Senior Front-end Engineer

The company is transforming precision medicine for the brain, from clinical development to clinical care. For Life Sciences partners, we offer the leading at-home EEG platform for clinical development of novel therapeutics for neurological, psychiatric, and sleep disorders. Our Diagnostics business is building the most comprehensive at-home platform for precision diagnostics, combining EEG and cardiopulmonary signals to deliver reimbursable assessments for sleep and central nervous system disorders. Together, we're changing the way patients are diagnosed and treated for any disorder that affects brain physiology.

As a Senior Front-end Engineer, you’ll help power the company's mission by building first-class web applications that

• drive forward new EEG analysis with data analytics capabilities

• manage clinical studies of novel therapeutics

• enable physicians to diagnose patients through at-home sleep tests

This isn’t just another web app — you’ll be crafting tools that help unlock insights into neurological, psychiatric, and sleep disorders, with the potential to improve lives at scale.

This role is 100% remote from anywhere in the U.S. The company's robust asynchronous work practices ensure a first-class remote work experience, but we also have in-person office hubs located in Boston and New York.
