About the role
The Translational Research team is hiring a Senior Research Associate to lead the cellular and molecular characterization of delivery and editing platforms supporting our preclinical programs. This is a hands-on bench role with significant ownership of experimental design, execution, and data interpretation.
Responsibilities
- Design, develop, and qualify molecular assays to measure CRISPR editing outcomes in vitro and in vivo, including amplicon NGS for indel quantification, TIDE/ICE, ddPCR, and orthogonal confirmation methods.
- Lead cell-based pharmacology assays evaluating delivery efficiency, editing efficiency, and on-target activity of LNP- and antibody-based delivery platforms.
- Plan and execute in vivo studies in mice evaluating biodistribution, editing efficiency, and pharmacodynamic activity; analyze tissues for nucleic acid and protein endpoints.
- Extract and purify RNA, DNA, and protein from cultured cells and animal tissues; run downstream analytical workflows (qPCR, RT-qPCR, Sanger and NGS sequencing, ddPCR, Western blot or Jess, ELISA, flow cytometry).
- Maintain primary and immortalized mammalian cell lines using aseptic technique; perform transfection and electroporation of CRISPR reagents.
- Analyze experimental data, interpret results in the context of program goals, and present findings in team meetings and written reports.
- Contribute to study design, protocol development, and SOPs.
- Mentor junior research associates and support cross-functional collaboration with Delivery, Editing, and Translational teams.
- Maintain rigorous electronic and paper lab records consistent with reproducibility and data integrity standards.
Qualifications
- BS with 6+ years or MS with 4+ years of hands-on research experience in molecular and cell biology in industry or academia.
- Demonstrated expertise in mammalian cell culture and design, execution, and troubleshooting of cell-based assays.
- Strong working knowledge of core molecular and analytical methods: PCR, RT-qPCR, Sanger and NGS sequencing, SDS-PAGE / Western blot (or Jess capillary electrophoresis), ELISA, and flow cytometry.
- Mammalian cell culture, cell transfection, and sterile techniques.
- Experience designing and executing in vivo rodent studies, including tissue collection and downstream analysis.
- Ability to independently scope, plan, and execute experiments with minimal supervision; track record of contributing to project decisions based on data.
- Clear written and verbal communication; comfortable presenting data to a scientific audience.
Preferred Qualifications
- Hands-on experience with hematopoietic stem cells (HSCs / HSPCs), including isolation, ex vivo expansion, and multilineage differentiation assays (CFU, erythroid, myeloid).
- Experience with LNP-based delivery of nucleic acids, including formulation handling, dose preparation, and in vivo administration.
- Experience with antibody-based or receptor-targeted delivery strategies.
- Familiarity with bioinformatics tools for amplicon sequencing analysis (e.g., CRISPResso, CRISPRessoBatch).
- Prior experience supporting IND-enabling or GLP studies.
