About the Role

This Scientist II role involves independently designing, executing, and analyzing research studies to drive analytical development projects for AAV-based gene therapy programs. The position offers technical leadership in assay development, optimization, qualification, validation, and transfer, including cell-based potency and molecular methods. The role requires applying broad scientific knowledge to establish AAV mechanisms of action, resolve technical issues, and support GMP manufacturing and regulatory submissions.

Responsibilities

  • Independently design and optimize analytical methods involving in-vitro cell culture and AAV transduction to demonstrate potency of the gene therapy vectors
  • Assist in the timely development and internal testing of CQAs, including potency assays, in a target-specific manner
  • Generate high-quality, reproducible data to support assay qualification, validation, method transfer, and QC-related activities for GMP material release
  • Analyze, interpret, summarize, and communicate findings through technical reports and presentations
  • Assist in driving analytical strategy and support regulatory submissions in collaboration with internal groups across CMC, Quality, and CROs
  • Identify technical risks related to assay performance, evaluate relevant factors, and develop mitigation strategies, novel processes, or alternative approaches
  • Collaborate on and review technical documentation and protocols to support late-phase assay validation projects at respective CDMO/CROs
  • Maintain accurate laboratory records and ensure compliance with company policies and regulatory standards
  • Apply industry best practices, regulatory expectations, and quality standards related to analytical development for gene therapy products
  • Apply results and learnings from previous studies, and assimilate knowledge or techniques from adjacent scientific fields, to address new or different problems
  • Collaborate and build constructive relationships across departments; serve as a technical resource and provide scientific coaching and technical guidance

Requirements

  • BS in Biology, Chemistry, Biochemistry, Biotechnology, Pharmaceutical Sciences, Chemical Engineering, or a related scientific discipline with 6-8 years of relevant experience (MS with 4-6 years or PhD with 1-3 years of relevant industry experience)
  • Experience in cell and gene therapy products
  • Strong hands-on experience with tissue culture, analytical assay development and execution, data analysis, and troubleshooting
  • Experience with pharmaceutical drug-process validation and manufacture a plus
  • Knowledge of FDA, cGMP, and ICH guidelines and QBD principles a plus
  • Strong organizational skills, attention to detail, and data accuracy
  • Excellent communication, collaboration, and problem-solving skills with the ability to work effectively across functional teams
  • Cross functional acumen and highly skilled in working with complex issues and creating direction in shifting priorities and ambiguity
  • Results oriented with breadth and depth in pharmaceutical development and commercial products to resolve complex problems
  • Results-oriented, with strong initiative, accountability, and willingness to take ownership of projects, deliver milestones, and drive work to completion

Skills

  • Cell-based potency assays
  • Molecular methods (qPCR, ddPCR)
  • Tissue culture
  • Analytical assay development
  • Analytical assay execution
  • Data analysis
  • Troubleshooting
  • Benchling or Quartzy (preferred)
