Software Engineer, Full Stack

Company OverviewImmunityBio, Inc.

We envision a day when we no longer fear cancer, but can conquer it, thanks to the biological wonder that is the human immune system.

The goal: to reprogram the patient’s immune system and treat the host rather than just the disease.
