Company Overview

Prime Medicine was founded to bring the promise of gene editing to patients. We use Prime Editing, a next-generation technology that can “search and replace” to restore normal genetic function almost anywhere in the genome. Prime Editing searches to find the precise place in the genome to edit and replaces the segment of faulty DNA with a correct copy of DNA.  A single Prime Editor can correct the individual mutations found across patients, meaning Prime Editing can potentially address more than 90 percent of known disease-causing genetic mutations.  

We envision a world where this technology can cure, halt, and ultimately prevent genetic diseases, providing lifelong benefit to patients.  Prime Medicine offers the opportunity to shape the future of gene editing and transform how medicines are used to treat disease. Realizing the promise of Prime Editing requires a talented team with diversity of viewpoints and expertise. We’re building a group of dedicated, scientifically curious individuals who are passionate about helping patients live longer, healthier lives.

Position Overview:

We are currently seeking a talented and motivated Principal Associate Scientist/Scientist I Scientist I with strong expertise in analytical characterization of biomolecules to join the analytical development team in Prime’s growing Technical Development and Operations group. The candidate will play a key role in the development and application of a variety of analytical assays for the characterization of Prime editing drug products across Prime’s portfolio, with an initial focus on adeno-associated virus (AAV) testing and characterization. This is a hands-on role that provides an exciting opportunity to gain direct experience in analytical method development and qualification. The ideal candidate will excel as a member of a cross-functional team that works closely with process development, formulation, pharmacology, quality, and external partners to advance the Prime Editing therapeutic product pipeline.

Key Responsibilities:

  • Support all aspects of analytical development for drug products, including routine sample analysis, release and characterization testing, new analytical method development, method qualification, comparability, and stability testing.
  • Perform method development, optimization, qualification, and validation, and assist in method transfer to internal teams as well as external CTLs (contract testing labs) and CDMOs (contract development and manufacturing organizations).
  • Identify, evaluate, develop, validate, and implement method improvements and new analytical technologies to augment Prime’s analytical capabilities.
  • Collaborate with research, process development, and formulation groups and effectively communicate results to multi-disciplinary teams in oral and written formats.
  • Participate in drafting, reviewing of protocols, SOPs, technical reports, and analytical sections of regulatory submissions
  • Maintain electronic lab notebook following data integrity principles and practices.
  • Adhere to all laboratory safety requirements and procedures.


  • MS/PhD in Analytical Chemistry, Biochemistry, Pharmaceutical Sciences, or related discipline.
  • At least 2-5 years’ experience in the biotechnology or pharmaceutical industry for MS candidates, and 0-1 years for PhD candidates.
  • Experience in developing and running analytical methods for characterizing AAVs/viral vectors is required.
  • Strong foundation in molecular assays (e.g., PCR) is required.
  • Knowledge of NGS-based workflows and understanding of CRISPR biology/prime editing are highly desired.
  • Willingness to learn new analytical technologies for Prime editing drug product characterization.
  • Experience in nucleic acids (DNA/RNA) characterization is a plus.
  • Experience with separation-based method development (e.g. CE) and immunoassays (e.g., ELISA) is a plus.
  • Self-motivated, and highly independent.
  • Detail-oriented and excellent at troubleshooting complex technical challenges.
  • Strong written and verbal communication skills.
