## Job description

Meet Ascertain Ascertain is building AI agents to automate the administrative work that burdens care teams. We are in major health systems and large specialty groups, saving hundreds of staff hours every week. Our backers include Northwell Health, New York’s largest health system, and Deerfield Management, a leading healthcare investment firm. Together, we’re on a mission to restore time, trust, and focus to the people who keep healthcare running.

You’ll work closely with healthcare providers to reduce administrative burdens and streamline detailed workflows. Day-to-day, this includes manually processing authorizations and overseeing automated submissions for office visit referrals, procedures, pharmaceuticals, and more.
