About the Role

Join our Bioanalytical Sciences team to develop and execute bioanalytical assays for preclinical translation and development. This hands-on role involves evaluating PRINT™-delivered payloads in disease-relevant contexts to generate data guiding candidate selection and advancing therapeutic programs toward clinical development, focusing on obesity and metabolic disease programs.

Responsibilities

  • Design, develop, validate, and execute in vitro, cell-based, and ex vivo assays to evaluate the efficacy, pharmacology, and delivery of various payloads using PRINT™ technology.
  • Develop and execute pharmacodynamic assays to measure transgene expression, protein production and secretion, enzymatic activity, receptor engagement, and downstream biological responses.
  • Develop and run cell-based functional assays to evaluate therapeutic efficacy across obesity and other metabolic diseases.
  • Establish assays using primary cells, immortalized cell lines, and tissue-derived samples to support translational studies.
  • Collaborate with in vivo pharmacology teams to analyze plasma and tissue samples from rodent and non-human primate studies.
  • Ensure accurate and reliable results through meticulous hands-on execution and record-keeping.
  • Support PK/PD characterization by generating quantitative bioanalytical data to inform dose selection and mechanism of action.
  • Contribute to assay transfer, qualification, documentation, and implementation of best laboratory practices.
  • Collaborate with internal teams and partners to integrate and optimize current and new assay technologies and methodologies.
  • Analyze experimental data, interpret results, and present findings in team meetings.
  • Contribute to troubleshooting and refining assay protocols.
  • Stay up to date with relevant scientific literature and emerging technologies.
  • Provide input on potential improvements or innovations in assay development and genomic medicine applications.
  • Contribute to data packages supporting IND-enabling studies, partnership diligence, and investor milestones.

Requirements

  • Ph.D. in molecular biology, biochemistry, pharmacology, cell biology, or a closely related field (relevant industry experience considered in lieu of Ph.D.).
  • Proficiency across standard molecular/biochemical assay platforms: ELISA, MSD, AlphaLISA, ddPCR, qPCR, Western blot, flow cytometry, and microscopy.
  • Experience in mammalian cell culture to support cell-based assays.
  • Ability to independently design experiments, troubleshoot, and interpret data.
  • Clear and organized scientific communicator, comfortable presenting data to cross-functional audiences.
  • Familiarity with obesity biology, metabolic disease, GPCR pharmacology.
  • Experience with genomic medicines, mRNA, or RNA-based therapeutic modalities.
  • Exposure to NHP or translational PK/PD study design.
  • Experience with animal models of disease is a plus.
  • Familiarity with HTS or automated liquid handling platforms.
