About the Company:

NIRSense is a cardiology company focused on developing world-leading non-invasive medical devices. Our tools measure oxygenation changes in the body 10x deeper than typical pulse oximetry and track the electrophysiological activity of muscles and the brain. We are a growing team of technology developers seeking candidates interested in helping advance our capabilities for a wide range of interested stakeholders who are driven to transform the way humans understand and interact with their own health.

Job Summary:

NIRSense is seeking an experienced senior electrical engineer to join our engineering and scientific team on a contract basis in its Morrisville, NC office. Working alongside our internal engineers, this person will support hardware development across NIRSense's product portfolio, with a primary focus on bringing up new board designs and troubleshooting battery-powered embedded systems. The ideal candidate is a hands-on engineer who is comfortable in the lab, has taken multiple battery-powered products from first power-on through a working system, and can diagnose and resolve hardware issues across power, analog, and mixed-signal domains.

Compensation: The engagement rate will be commensurate with the successful applicant's experience.

Hours: Contract

Travel: 0-5%

Minimum Qualifications:

• 5+ years of hands-on electrical engineering experience, with significant focus on battery-powered embedded or wearable systems.
