Senior/Research Associate, mRNA Engineering

About 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. What you'll do As a Member Of Our Team, You Will mRNA production Execute established protocols for DNA template preparation, in vitro transcription, and downstream purification to generate research-grade mRNARun routine analytical assays to assess mRNA integrity and purityUnder the guidance of senior scientists, help troubleshoot production issues and contribute to experiments that optimize yield, purity, and recovery Documentation and lab operations Maintain detailed, accurate records of all experiments in Electronic Lab NotebooksFollow and help maintain SOPs; contribute to drafting and updating protocols as workflows evolveManage raw material and mRNA inventory, including sample tracking, storage, and reagent orderingMaintain lab equipment and follow lab safety practices Collaboration Work closely with Delivery Sciences and research teams to coordinate material needs and hand off mRNA for downstream studiesPresent experiment results at team meetings Requirements B.S. in Life Sciences, Chemistry, Engineering, or a related field with 1-2 years of relevant full-time industry or academic research experience, or M.S. in Life SciencesHands-on experience with molecular biology techniques such as cloning, nucleic acid purification, PCR, and gel electrophoresisStrong attention to detail and good documentation practicesAbility to execute protocols accurately and manage multiple tasks efficientlyExcellent communication and organizational skillsInterest in mRNA process science and eagerness to learn new techniques Nice to have Experience producing mRNA through IVT and downstream purificationFamiliarity with plasmid and mRNA analytics such as HPLC, UV-Vis, and TapeStation/CGEExperience with plasmid DNA preparation and linearizationExposure to column-based purification and tangential flow filtration (TFF)Familiarity with automation liquid handling-based methods for mRNA purification, including experience operating such as Hamiltons and Tecans Benefits NewLimit offers generous benefits to ensure our team can focus on our mission: Health, dental, and vision insurance401(k) with company matchPaid parental leaveIndustry-leading paid time off (PTO) — 20 days/year for all employees + holidaysMeals and snacks on-site Salary Range: $75,000 - $100,000*.
