Co-Op, In Vitro Biology

The Role Moderna is seeking a highly motivated co‑op with a strong interest in cell biology, assay development, and drug delivery to join our team. This is a full‑time co‑op based in Cambridge, MA from January 18, 2027 – June 25, 2027. Candidates must be available for the entire duration of the program. The co‑op will support the development and application of in vitro assays within Moderna’s research and technology development efforts.

The role provides hands‑on experience in cell culture, cell‑based assay development and optimization, plate‑based screening, microscopy, data analysis, and the characterization of novel delivery technologies. This role offers meaningful, practical experience in a collaborative and multidisciplinary research environment, with the opportunity to take ownership of a defined scientific project and contribute to ongoing research and technology development initiatives.

• Develop and execute plate‑based cell assays and microscopy workflows to evaluate novel delivery technologies.
• Optimize cell‑based assays for robustness, reproducibility, and scalability by systematically evaluating key cell culture and assay parameters.
• Establish experimental controls, quality criteria, and standardized workflows to ensure consistent assay execution and interpretation.
• Design and conduct follow‑up studies to characterize promising candidates in relevant cellular models.
• Apply molecular and cell biology approaches to investigate biological factors influencing delivery performance.
• Execute and troubleshoot experimental protocols, adapt new methods, and leverage scientific literature to guide experimental design.
• Analyze, interpret, document, and communicate experimental results to multidisciplinary project teams.
• Collaborate with scientists across multiple disciplines to advance research objectives.

• Currently pursuing a BS, MS, or equivalent degree in cell biology, molecular biology, bioengineering, biomedical engineering, biochemistry, pharmaceutical sciences, or a related scientific discipline.
• Hands‑on laboratory experience with mammalian cell culture and a strong foundation in cell and molecular biology.
• Experience with cell‑based assays and plate‑based experimental workflows.
• Ability to organize and document experimental work clearly and maintain accurate laboratory records.
• Strong communication skills and enthusiasm for presenting and discussing scientific results.
• Ability to work both independently and collaboratively in a multidisciplinary, fast‑paced research environment.

• GPA of 3.5 (on a 4.0 scale) or equivalent academic achievement.
• Experience with fluorescence microscopy or imaging techniques.
• Familiarity with quantitative data analysis and visualization using tools such as Excel, Graph Pad Prism, or similar software.
• Demonstrated ability to troubleshoot experiments, think critically about experimental results, and learn new laboratory techniques.
