Join us in creating the ultimate gene therapy products to cure genetic diseases in children and adults. 4D Molecular Therapeutics headquarters are located in Emeryville, CA.

GENERAL SUMMARY:

The position of Senior Scientist, Analytical Development team, will lead the development and optimization of cell-based assays/bioassays/nucleic acid-based assays for the lot release and characterization of AAV-based gene therapy drug substance and drug product. The successful candidate will be experienced with development and validation of in-vitro potency assays and will drive the phase-appropriate method development, optimization, qualification and tech transfer. He/She will have leadership to manage 1~2 junior level scientists and to manage internal (R&D, PD, Quality, Manufacturing and Facilities) as well as external collaborations (CRO, CDMO). This is a CMC and not R&D position.

RESPONSIBILITIES:
  • Key driver to develop and optimize phase-appropriate potency assays/lot release assays and broad spectrum of characterization assays using immunoassays, nucleic acid-based assays based on thorough understanding of the scientific background of the products, applicability of the emerging or existing bioassay platforms and phase-appropriate GMP requirements for AAV based gene therapy product
  • Responsible for the Bioassays supporting formulation and stability studies
  • A strong scientific leader who can independently design and execute effective experiments with clear goals of answering key questions to drive assay development and troubleshooting in a very face paced environment. Interprets data and effectively communicates information or risk mitigation strategies that drive critical decisions in CMC department
  • Authors technical reports and SOPs and assists the functional head of Analytical Development to prepare relevant sections of regulatory filings
  • Manages and provides technical expertise to Research Associates and/or Scientists in an assay development as well as routine testing efforts
  • May serve as a scientific liaison for outsourced assay development, technology transfer and data management in a CRO or CMO/CDMO environment
  • Expected to be informed on matters of state-of-the-art or innovative technologies that advance AAV characterization and integrate within the department
  • Other duties as assigned


QUALIFICATIONS:
  • Education:
  • PhD in a relevant area of specialization (biological sciences, cell biology, molecular biology, virology)


  • Experience:
  • 5+ years of industry within the Biotech or similar industry
  • GxP experience in analytical method development and qualification under ICH/FDA guidelines is required. Experience in a CMC group (QC/Analytical Development) is strongly desired
  • Demonstrated experience with potency assay development for biologics or gene therapy products is required.
  • Demonstrated leadership and track record of successfully developing different spectrum of bioassays by utilizing appropriate methodologies (i.e cell imaging systems, flow cytometry, qPCR, ddPCR etc)
  • Must have thorough understanding of cell biology required for development of robust cell-based assays
  • Thorough understanding of developing phase-appropriate potency assays using parallel line analysis
  • Good understanding of high-content imaging system and image analysis is preferred
  • Experience in writing SOPs, developmental and technical reports, contributions to regulatory submission documents to support CMC efforts
  • Prior working experience on biologics, vaccines, AAV gene therapy drugs or nanoparticle drug deliveries is desirable
  • Ability to bring in and assess value-added platforms based on special needs associated with characterization of the gene therapy drug products


  • Skills:
  • Strong verbal and written communication skills and effective interpersonal, technical discretion and troubleshooting skills are essential
  • Must be a team player, strong critical thinker, exhibit a willingness to meet project timelines and multitask effectively in a dynamic fast-paced environment under challenging timelines
  • Demonstrated history of working independently, with minimal supervision, and managing multiple projects
  • Strong attention to detail supported by excellent time management and organizational skills
  • Proficient or familiar with Microsoft based Windows programs: Word, Excel and Powerpoint as well as analytical software such as Softmax Pro and statistical software such as GraphPad, Minitab, JMP or Spotfire


  • Work Location:
  • This position requires the ability to work on location in the 4DMT lab at least 3-4 times a week. There may be some remote work during Shelter in Place.
  • Once Shelter in Place has been lifted this will be full-time position at the 4DMT Emeryville location
