Principal Scientist, Immunogenicity and Ligand Binding Assays

The Role:

Joining Moderna means advancing mRNA science to transform medicine. Work with exceptional global teams on a broad pipeline and build a career that makes a real difference for patients.

This role sits at the forefront of Moderna’s clinical bioanalytical strategy, providing deep scientific expertise and hands-on leadership across immunogenicity and ligand binding assay (LBA) bioanalysis for our mRNA-LNP therapeutic pipeline. As an individual contributor, you will shape and execute phase-appropriate bioanalytical strategies that enable critical clinical development decisions while ensuring the highest standards of scientific rigor and regulatory compliance.

Working closely with cross-functional development teams, you will drive regulated immunogenicity and bioanalytical activities spanning assay development, validation, sample analysis, data interpretation, and regulatory support. You will play a pivotal role in advancing innovative medicines through clinical development while leveraging modern digital capabilities and emerging analytical technologies, including opportunities to work alongside advanced data and AI-enabled approaches that accelerate scientific insight generation.

Here’s What You’ll Do:

• Provide scientific and hands-on oversight of ligand binding assay (LBA)-based bioanalyses supporting Moderna’s mRNA-LNP therapeutic development programs.

• Support and oversee the Immunogenicity function through clinical science-driven, phase-appropriate, and risk-based bioanalytical development strategies across advancing stages of clinical development.

• Lead and facilitate anti-drug antibody (ADA) assay and neutralizing antibody assay regulated method development, validation, and clinical sample testing activities.

• Ensure in-house GcLP compliance across the LBA team, systems, and procedures, maintaining rigorous laboratory practices and regulatory requirements for analytical activities through a phase-appropriate approach.

• Design and execute phase-appropriate clinical analytical strategies supporting development programs.

• Drive development, validation, and implementation of:

  • Cell-based assays
  • Immunoassays
  • Quantitation of translated proteins
  • Pharmacokinetic (PK) assays
  • Pharmacodynamic (PD) assays

• Review and evaluate raw analytical data, assay validation data, and study reports to ensure scientific integrity, data quality, and compliance with current regulatory, industry, and Moderna standards.

• Assess analytical performance and laboratory compliance to ensure data generated meet both scientific and regulatory expectations.

• Collaborate with internal and external stakeholders to support clinical bioanalytical activities throughout the product development lifecycle.

• Contribute to regulatory submissions and support responses to regulatory authority questions and information requests.

• Maintain current knowledge of emerging scientific literature, industry best practices, regulatory expectations, and evolving guidance related to clinical bioanalysis.

• Ensure adherence to Good Clinical Laboratory Practice (GcLP), Good Laboratory Practice (GLP), Good Clinical Practice (GCP), internal SOPs, applicable regulations, guidance documents, and relevant white papers.

• Apply scientific judgment and risk-based decision making to support robust bioanalytical strategies that accelerate development while maintaining quality and compliance.

• Partner with multidisciplinary teams to advance innovative analytical approaches and continuously improve laboratory and bioanalytical processes.

The key Moderna Mindsets you’ll need to succeed in the role:

• We obsess over learning. We don’t have to be the smartest we have to learn the fastest.

• We act with dynamic range, driving strategy and execution at the same time at every step.

Here’s What You’ll Need (Basic Qualifications)

• A Ph.D. in infectious disease, Immuno-oncology, Immunology, Cancer Biology, or related fields and a minimum of 10+ years of industry biotech/pharmaceutical experience. M.S. with extensive bioanalytical experience are considered

• Experience with RNA, biologics and cell therapy preferred

• Experience of various platforms such as ECL, Gyrolabs, reporter gene assays, DelPhia assays and other methodologies for clinical assays.

• Ability to effectively communicate scientific concepts, program objectives, data analysis within a matrix environment.

• Knowledge of GLP requirements and understanding of current industry trends and regulatory expectations associated with bioanalytical science.

• Experience on Watson LIMS and LabVnatage eLBN would be an advantage.

• A desire to make an impact as part of a high-growth, transformational companythat is Bold, Relentless, Curious, and Collaborative.
