Senior Quality Control Associate - Capsid ID

  • Full-time

Company Description

Rejuvenate Bio is using a convergent, multi-disciplinary approach, combining gene therapy, proprietary targets, and the animal health market to bring human age-related therapies to market. We are targeting the core drivers of chronic age-related diseases by unlocking the power of gene expression and epigenetic reprogramming to reverse pre-existing heart disease, metabolic disease, and kidney failure in humans.

Each therapy we’re developing has the potential for therapeutic impact across multiple disease indications, with each new piece of data validating the approach and increasing the value of each clinical program. This will allow us to rapidly expand each product into multiple indications. Additionally, our animal health programs provide an untapped market for early revenue and further validation for use in humans.

Job Description
