Scientist I – Vector Development

Weill Cornell Medical College•New York, NY
•$70,200 - $83,200

About The Position

The Scientist I supports viral and non-viral vector development and genetic construct workflows in a fast-paced, collaborative, execution-focused translational research environment. The role works closely with senior scientists on lentiviral vector design, mRNA delivery systems, and transposon-based construct engineering. It is suited to someone with hands-on molecular biology skills who can deliver careful, reproducible work in a detail-oriented laboratory setting. The position offers exposure to advanced gene delivery systems and opportunities for technical growth in translational genomics and gene therapy.

Requirements

  • Bachelor’s degree in Biology, Molecular Biology, Biochemistry, Biotechnology, or a related field.
  • 1–3 years of hands-on laboratory experience in molecular biology and primary cell cultures in an academic or industry setting.
  • Proficiency in mammalian tissue culture, including passaging, counting, maintenance, and freezing and thawing cells.
  • Experience with bacterial culture and plasmid propagation.
  • Experience performing plasmid DNA purification workflows.
  • Familiarity with standard molecular biology techniques, including pipetting, PCR, gel electrophoresis, and restriction digests.
  • Experience or familiarity with lentiviral vector production.
  • Understanding of sterile technique and biosafety best practices.
  • Familiarity with basic viral handling or BSL-2 laboratory environments.
  • Ability to follow detailed experimental protocols with high reproducibility.
  • Strong attention to detail and experimental consistency.
  • Ability to execute complex protocols accurately and reliably.
  • Strong organizational and documentation skills.
  • Collaborative mindset and willingness to support team-based research goals.
  • Eagerness to learn advanced molecular and gene delivery techniques.

Nice To Haves

  • Knowledge or experience with viral vector production downstream engineering, including filtration and chromatography, especially for lentiviral systems.
  • Experience with transfection methods such as PEI, lipid-based reagents, or electroporation.
  • Experience with DNA construct screening and validation workflows.
  • Exposure to cell-based functional assays or flow cytometry.

Responsibilities

  • Perform routine and advanced mammalian cell culture, including maintenance of adherent and suspension cell lines.
  • Assist with preparation and handling of reagents for transfection and transduction experiments.
  • Prepare plasmid DNA, including Maxiprep workflows.
  • Support plasmid construct quality control using restriction digest analysis, PCR, and basic sequencing preparation.
  • Conduct lentiviral production workflows, including transient transfection of packaging systems, viral harvest, and downstream processing such as concentration and purification.
  • Assist with viral titering, concentration, and basic functional validation assays.
  • Support cloning workflows, including bacterial transformation, colony screening, and plasmid expansion.
  • Perform sterile-technique molecular and cell biology experiments with accuracy and reproducibility.
  • Maintain detailed and accurate laboratory records, including experimental notes.
  • Collaborate with senior scientists on iterative construct design and testing cycles.
  • Maintain laboratory organization and reagent stocks, and follow applicable biosafety protocols, including BSL-2 practices.
