The Role
As part of our vision, Moderna is committed to investing in R&D to further expand our impact on patients. In this role, you will work in the Genome Sciences team to develop and execute cell-based and molecular assays that support programs across Genome Sciences and Moderna’s mRNA platform to develop cellular engineering technologies. You will help generate high-quality, decision-driving data through the design, development, and execution of in vitro experimental systems, with an emphasis on rigorous execution, goal-focused troubleshooting, and cross-functional collaboration. The ideal candidate brings strong immune cell culture experience combined with demonstratable expertise and experience in immediate downstream molecular- and cell-based assays.
Here’s What You’ll Do
Culture, maintain, and experimentally manipulate mammalian cell lines and primary human cells to support assay development and screening activities.
Execute cell-based experiments to evaluate nucleic acid delivery, expression, durability, and related molecular and cellular outcomes.
Execute flow cytometry-based assays to assess cell phenotype, viability, transfection or expression readouts, and other relevant cellular outcomes.
Design, optimize, and execute qPCR assays for DNA and RNA quantification, including primer/probe design, assay qualification, controls, and standard curves.
Collaboratively develop and implement ddPCR workflows to quantify vector copy number and other DNA-based readouts relevant to genomic sciences studies.
Partner closely across teams to generate high-quality samples and support PCR and potentially other molecular or sequencing workflows.
Analyze, interpret, and present high-quality experimental data in accordance with project timelines.
Maintain accurate, detailed ELNs and records and help establish robust workflows, controls, and best practices.
Execute and troubleshoot standard protocols, independently adapt new methods into practice, and incorporate additional assays as program needs evolve.
Additional duties as may be assigned from time to time.
Here’s What You’ll Need (Basic Qualifications )
Minimum Education: BS/BA in molecular biology, cell biology, immunology, virology, biotechnology, bioengineering, or a related field with 2+years of experience
Strong mammalian cell culture experience, particularly with primary immune cell types such as T cells and PBMCs, with proven ability to generate reproducible, high-quality data.
Demonstrated expertise in qPCR or ddPCR assay design, development, optimization, and data interpretation.
Excellent organizational, documentation, and cross-functional communication skills.
Enthusiasm and a passion to deliver the greatest possible impact to people through mRNA medicines.
