Senior Scientist - Target Discovery and Molecular Biology

  • 3650 Dunhill St, San Diego, CA 92121, USA
  • 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

Senior Scientist - Target Discovery and Molecular Biology

The ‘Target Discovery and Molecular Biology Scientist’ position will directly support efforts to build our early-stage pipeline. The successful candidate will be responsible for using their knowledge of molecular biology to investigate new therapeutics for treating aging and age-related diseases as well as supporting current discovery-phase projects. This position will also focus on implementing molecular biology techniques to support ongoing and future genome engineering research efforts towards the discovery and development of molecular tools for controlled gene therapies. The position reports to the Head of Basic Research of Rejuvenate Bio.

Will use technical expertise in genetic engineering and biotechnology with a wide range of molecular biology techniques including, CRISPR-Cas9, shRNA & RNAi mediated genetic editing, genetic engineering using various synthetic biology tools and mutant creation, molecular cloning techniques, cell/tissue handling, PCR/qPCR, flow cytometry, signaling pathway deconvolution using various protein biology tools, and downstream data curation and interpretation. Will conduct molecular biology projects in a variety of cellular as well as animal models, effectively troubleshoot technical problems, and collect, interpret and present resultant data in both written and oral form to a varied audience.

Responsibilities will include:

  • Setting, completing and updating milestones related to projects.
  • Performing cell culture for virus expression and purification when needed.
  • Help oversee research associates and contract research organizations when used to conduct experiments.
