Prior Authorization Assistant, Oncology

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. Our work is urgent — not because of startup timelines, but because our customers rely on us to drive financial resilience and operational clarity in a system under strain.

About the Job:

This is a hands-on role for someone who thrives in high-volume operational environments and is comfortable balancing individual contribution with team support.

You will continue to process prior authorizations directly—often at high volume—while also serving as a go-to resource for other Ascertain Assistants. Over time, this role will evolve into a hybrid operations + technology position as workflows become increasingly automated and integrated with Ascertain’s platform.
