About the Job

Requirements

  • A B.S. or M.S. in Biochemistry, Molecular Biology, Chemical Engineering, Virology, or a related field, with 2–5 years of relevant industry experience.
  • Hands-on experience producing AAV in HEK293 cells by triple transfection, at scales from 1 L or less to 50 L or greater.
  • Proficiency with downstream purification techniques, including affinity and ion-exchange chromatography, or gradient ultracentrifugation.
  • Experience with viral-genome titer assays, including qPCR and ddPCR, and capsid quantification using ELISA, A260/280, or western blot.
  • Working knowledge of purity and impurity assays such as SEC-HPLC/UHPLC, capillary gel electrophoresis, LC-MS, and SDS-PAGE.
  • Ability to troubleshoot analytical methods and interpret data to inform process decisions.

Responsibilities

  • Produce, purify, and qualify AAV vector lots from plasmid DNA through study-ready material.
  • Maintain and troubleshoot cell-culture systems.
  • Develop and execute quality-control assays; analyze, interpret, and report data.
  • Conduct process-optimization experiments to improve yield and quality.
  • Process ex-vivo tissues for next-generation sequencing analysis.
  • Communicate progress, timelines, and results to cross-functional teammates.
  • Scale transient transfection, optimize downstream purification processes, and perform characterization assays to generate qualified AAV lots for rodent and non-human primate in-vivo studies.

Desired Qualifications

  • Prior experience leading or supporting AAV campaigns of at least 1 × 10¹⁵ vg for non-human primate studies.
  • Protein purification experience using AKTA-FPLC, affinity chromatography, preparative SEC, or ion-exchange chromatography.
  • Library-scale cloning experience, including Golden Gate Assembly or Gibson Assembly.
  • Next-generation sequencing library-preparation experience.
  • Experience with other viral vectors, such as lentivirus or adenovirus, or with lipid-nanoparticle formulation.

About the Company

Manifold Bio

In vivo precision biologics design platform

Manifold Bio creates precision biologics by designing drugs inside living organisms. Its in vivo drug design platform uses a proprietary mCodes protein barcoding system to multiplex multiple proteins in one experiment, enabling pooled in vivo testing of complex biologics. This makes it easier to study and optimize large, biologic drugs in a living system rather than in a test tube. The company differentiates itself as the first to offer an in vivo design platform powered by protein barcodes, allowing researchers to test many proteins at once and streamline drug discovery for complex biologics. Its goal is to expand its in vivo design platform and license or partner its technology with other pharmaceutical and biotech companies to develop new therapeutics.
