The posting, in NewLimit's own words
archived Oct 21, 2026About NewLimit
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.
Position
We are seeking a Research Associate to join our mRNA Engineering team. In this role, you will generate the mRNAs that power NewLimit's research programs, executing the workflow from DNA template through in vitro transcription (IVT) and downstream purification. You will produce research grade mRNA materials, keep rigorous records of how each batch was made, and work closely with scientists across our research and Delivery Sciences teams. This is a lab-based role ideal for an early-career scientist who wants to build deep expertise in mRNA process development in a fast-paced research environment. You will receive hands-on training from expert scientists and see the direct impact of your work on our programs.
