Analytical Development Scientist/Sr Scientist

4D Molecular Therapeutics, located in Emeryville is a global leader in gene therapy product research & development using scientific innovation to unlock the full potential of gene therapy for patients with genetic diseases.  At 4D Molecular Therapeutics, our goal is to design and develop transformative gene therapy products using our proprietary adeno-associated virus variants platform to treat serious unmet medical conditions. We are seeking a talented and motivated Analytical Development Scientist/Sr Scientist to join our team in developing assays for release, characterization, and process development for novel AAV vectors.

Responsibilities include but not limited to:

  • Demonstrates innovative design, development, and execution of analytical projects through literature review and scientific teamwork. Leverages strong understanding of analytical biochemistry, including DNA-based assays (qPCR/ddPCR/NGS) and/or protein-based assays (HPLC, electrophoresis, ELISAs, CE) as well as cell-based assays, from early development through qualification and validation. Designs assess and interpret experimental data.
  • May manage Associates in either assay development or assay execution/routine testing. Reviews data and supports troubleshooting; manages analytical deviations.
  • Leads both from the bench (hands-on laboratory work) and from the desk (designing studies, analyzing data, preparing reports and documents). May work with CROs on assay development and transfer
  • Writes assay development reports, assay qualification and validation protocols and reports, and regulatory documents. Authors manuscripts and presents results at appropriate scientific meetings
  • Contributes to building a culture that embraces continuous learning, improvement and innovation, and encourages team members to expand their technical skill base and deepen their gene therapy expertise. Maintains a current awareness and contributes to current scientific literature; actively applies new concepts and technologies as appropriate
  • Leads and supports research initiatives such as new technology development and continuous improvement projects


  • Ph.D. Chemical engineering, Bioengineering, Biology, Biochemistry, Virology, or related field) with 2+ years experience, MS with 5+ years experience, or BS with 10+ years experience in analytical development/QC of large molecule or cellular therapies.
  • Extensive working knowledge of assay development, including DNA-based assays (qPCR/ddPCR/NGS) and/or protein-based assays (HPLC, electrophoresis, ELISAs, CE) and cell-based assays
  • Strong background in assay qualification/validation
  • Knowledge of viral gene therapy (adeno associated viral vectors) preferred
  • Experience managing Research Associates is desired but not requiredSuccessful demonstrated ability to work independently and lead others in designing and developing experiments, analyzing and interpreting data in a rigorous way
  • Ability to multi-task and support more than one project simultaneously
  • Ability to work in a team-based environment, cooperatively and supportive of multiple viewpoints and approaches
  • Understanding and knowledge of key scientific software programs
  • Understanding and knowledge of regulatory requirements for biologic products
  • Strong organizational skills, analytical and problem-solving skills
  • Strong communication skills both written and oral with demonstrated ability to present ideas and information and data effectively via one on one discussions, team meetings and partnership interactions
