Senior Scientist / Scientist, In Vivo Pharmacology

Company info NewLimit is a biotechnology company working to radically extend human healthspan. We’re developing medicines to treat age-related diseases by reprogramming the epigenome, a new therapeutic mechanism to restore regenerative potential in aged and diseased cells. We leverage functional genomics, pooled perturbation screening, and machine learning models to unravel the biology of epigenetic aging and disease using experiments of unprecedented scale. Description NewLimit is seeking a talented Scientist / Senior Scientist of In Vivo Pharmacology to join our Translational Sciences team. This critical role designs and executes in vivo studies to evaluate pioneering epigenetic reprogramming therapeutics across our entire portfolio. As a subject matter expert in nonclinical and PK/PD study design, you will lead in vivo pharmacology strategies, collaborate cross-functionally with therapeutic area teams, and directly drive therapeutic candidate selection.
