The individual will work closely with Analytical Development, Technical Operations, Regulatory Affairs, Quality Assurance, and external partners to ensure analytical methods, specifications, and testing programs support clinical development, process validation readiness, and future commercial requirements.

This position requires technical expertise in analytical testing, preferably of AAV-based products, as well as demonstrated experience overseeing external laboratories and driving cross-functional CMC initiatives.

Primary Responsibilities

  • Lead QC oversight of external contract testing laboratories supporting release, characterization, validation, comparability, and stability testing activities
  • Support product specification lifecycle management, including establishment, justification, trending, revision, and regulatory impact assessment
  • Partner with Analytical Development and Technical Operations to support method qualification, validation, transfer, verification, and continued performance monitoring across testing laboratories
  • Serve as QC subject matter expert for laboratory investigations, including OOS, OOT, atypical results, assay failures, and method performance events
  • Support reference standard qualification, lifecycle management, and analytical comparability initiatives
  • Provide technical oversight for method transfers, comparability assessments, and laboratory readiness
  • Collaborate with Regulatory Affairs and CMC teams to author and review regulatory submissions, responses to health authority inquiries, technical reports, and analytical sections of INDs, BLAs, and other global filings
  • Prepare and manage sample submission paperwork for external contract testing labs (CTLs), including quotes, purchase orders, shipping documents
  • Coordinate shipment of samples, reference standards, and reagents to and from manufacturing sites, external vendors, and CTLs in compliance with storage and shipping requirements
  • Collaborate with cross-functional CMC teams to align on sample submission and testing needs

Required Skills and Qualifications

  • Bachelor’s degree in a scientific discipline (e.g., Chemistry, Biology, Biotechnology); advanced degree (MS) a plus
  • 6+ years of experience or 4+ with Master’s (Sr. Manager level: BS with 8+ years or MS with 6+ years experience) in Quality Control, Analytical Development, Manufacturing Sciences, Quality Assurance, or related CMC functions within biotechnology or pharmaceutical organizations
  • Experience supporting late-stage development, process validation, and/or commercial readiness activities preferred
  • Experience supporting biologics, cell therapy, gene therapy, or other advanced therapeutics preferred
  • Strong understanding of cGMP regulations and global regulatory expectations applicable to analytical testing and Quality Control
  • Experience with analytical method lifecycle management, including qualification, validation, transfer, verification, and continued performance monitoring
  • Knowledge of analytical techniques commonly used for AAV and biologic products (i.e., ddPCR, cell-based potency, ELISA/immunoassays, residual impurities, compendial safety testing)
  • Strong understanding of analytical control strategy development and specification management

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
