Job Description:
Job Roles & Responsibilities:

What are the top 3-5 skills, experience or education required for this position?    

  • Master’s degree in Cell Biology, Molecular Biology, Biological Sciences, or a related field with 1-3 years of industry experience, OR Bachelor’s degree in a related field with 3+ years of industry experience.
  • Expertise in mammalian cell culture (suspension and adherent cell lines, primary T cells) and multi-color flow cytometry (panel design, acquisition, and analysis using FlowJo) is required.
  • Hands-on experience with immunological assays (e.g., ELISA, Luminex, cytotoxicity) is highly desirable.

 

Key Responsibilities:

  • Design and perform plate-based and cell-based assays (multi-color flow cytometry, Western blot, ELISA, etc.) to assess mRNA delivery and protein expression in mammalian cells using LNP systems.
  • Design and perform high-throughput expression and functional screen/characterization assays for novel protein/mRNA candidates, using semi-automated instruments.
  • Maintain meticulous records in an electronic lab notebook (ELN), draft standard operating procedures (SOPs), and present results at team meetings.
  • Independently plan, execute, and interpret experiments, delivering data-driven insights aligned with project timelines and goals.
  • Conduct molecular biology tasks, including cloning (e.g., PCR, golden gate, Gibson reactions, etc.), and optimize mRNA IVT protocols for yield and quality.
  • Design, produce, and optimize lentiviral vectors, perform transduction experiments, and analyze results to advance research objectives.
  • Stay current with advancements in genetic medicine, LNP technology, and molecular biology techniques to inform experimental design.
  • Collaborate with antibody discovery/production teams to support pipeline projects and facilitate technology hand-offs.

 

Qualifications:

  • Master’s degree in Cell Biology, Molecular Biology, Biological Sciences, or a related field with 1-3 years of industry experience, OR Bachelor’s degree in a related field with 3+ years of industry experience.
  • Expertise in mammalian cell culture (suspension and adherent cell lines, primary T cells) and multi-color flow cytometry (panel design, acquisition, and analysis using FlowJo) is required; Hands-on experience with immunological assays (e.g., ELISA, Luminex, cytotoxicity) is highly desirable.
  • Experience with semi-automated liquid handling systems (e.g., Integra VIAFLO) for high-throughput workflows is highly preferred.
  • Familiarity with data analysis tools (e.g., GraphPad Prism, FlowJo) is required; working knowledge with statistical and bioinformatics tools (python, R, etc.) is a plus.
  • Basic understanding of immunology, cancer biology, or cell therapy applications is preferred; Prior experience in genetic medicine, CAR-T cell therapy, or RNA therapeutics is a strong plus.
  • Basic knowledge of nucleic acid characterization (e.g., gel electrophoresis, qPCR), familiarity with molecular biology techniques, including cloning (e.g., Gibson assembly, PCR) and mRNA IVT (e.g., capping, purification), is a strong plus.
  • Strong organizational and time-management skills with a proven ability to juggle multiple projects.
  • Demonstrated ability to troubleshoot assays and optimize protocols independently.
  • Excellent verbal and written communication skills for presenting data and collaborating with cross-functional teams.
