****Important Application Note: Please Read Before Applying****

To be considered for this role, your resume must clearly demonstrate the following qualifications and experiences. Resumes lacking these specific qualifications may not be considered. Ensure your experience is prominently listed and detailed with the following:
  • Aseptic Cell Culture Techniques: Experience with standard aseptic cell culture, including culturing various primary cells, hepatocytes, and/or liver non-parenchymal cells. Experience with hepatocyte primary cell culture and isolation is essential.
  • Laboratory Techniques: Proficiency in cellular, biochemical, and molecular techniques, including:
  • Protein detection methods such as ELISA, MSD, and western blot.
  • Gene profiling techniques like RNA/DNA extraction and qPCR.
  • Cell imaging expertise (experience with high-content microscopy is a plus).
  • Cell-Based Functional Assays: Hands-on experience in transfection, cytotoxicity, cytokine release, and proliferation assays.
  • Co-Culture Systems and Microphysiological Systems (MPS): Experience with in-vitro co-culture systems or MPS is a plus.

Basic Qualifications
  • Demonstrated expertise with standard aseptic cell culture technique, including experience culturing various primary cells. Experience with hepatocytes primary cell culture is highly appreciated. Experience with hepatocytes and/or liver non-parenchymal cells isolation is a plus.
  • Broad experience with cell-based functional assays, including transfection, cytotoxicity, cytokine release, and proliferation assays. Experience with co-culture in-vitro or MPS is a plus.
  • Proficiency across cellular, biochemical, and molecular techniques including protein detection (ELISA, MSD, western blot), gene profiling (RNA/DNA extraction, qPCR) and cell imaging. Experience with high content microscopy is a plus.
  • Broad scientific knowledge in liver biology and non-viral delivery and molecular biology.
  • Self-motivated with strong time management and organizational skills
  • Flexibility to rapidly changing priorities and deadlines
  • Experience in preparing high quality documents including technical reports, presentations, SOPs, and experimental protocols.
  • Highly collaborative with demonstrated ability to work in a matrixed team environment.
  • Excellent oral and written communication skills

Key Responsibilities:
  • Maintain cultures of immortalized tumor cell lines, hepatic primary cell types (e.g. hepatocytes, LSEC and KC).
  • Perform hepatocytes mouse isolation from key disease models.
  • Optimize, design, execute, and interpret in vitro cell-based assays to characterize diverse mechanisms of gene therapies (e.g. ELISA, MSD, high content imaging)
  • Perform fit-for-purpose in vitro and ex vivo assays to assess phenotypic and functional read-outs to assess drug candidate toxicity and efficacy.
  • Prepare experimental protocols, analyze experimental data, and present study results in team and department meetings.
  • Document experimental methods and findings in electronic laboratory notebook

POSITION OBJECTIVES
  • Conduct and interpret cell-based in vitro assays to characterize mechanism of action related to non-viral gene therapy with focus on the hepatic environment:
  • Immunomodulation
  • Cargo cell localization
  • Support non-viral (LNP) oligo therapy screenings e.g. endosomal scape assessment
