Scientist I​/II, tLNP Process Development

Job Title

Targeted Lipid Nanoparticles Scientist

Overview:

Targeted lipid nanoparticles (tLNPs) are a key emerging modality for the effective delivery of mRNA therapeutics. The tLNP CMC Team (TCT), a newly formed group within Biologics CMC, Development Sciences, R&D, is seeking a scientist to join its tLNP Process Development team.

This team is responsible for the full manufacturing process from purified mRNA to purified tLNP bulk drug product: encapsulating mRNA with lipid components to form LNPs, conjugating LNPs with a targeting moiety, and purifying the final tLNPs via tangential flow filtration. The role focuses entirely on manufacturing process development, not on mRNA sequence design, lipid structure, or targeting moiety design.

The team's mandate spans the full pharmaceutical development lifecycle: optimizing process parameters and their impact on critical quality attributes, producing non-GMP pre-clinical and GMP clinical supply, leading commercial tech transfer, and authoring relevant CTD sections for regulatory submissions. Science-based, hands-on lab work is central, with first-principles and statistical modeling applied where appropriate.

Success in this role depends on close collaboration with the mRNA process development, drug product development, and analytical development teams, as well as cross-functional partners across Biologics CMC and Synthetic Molecule CMC. The work directly advances cutting-edge mRNA-based therapeutics.

Independently design, execute and interpret critical experiments to understand unit operations such as mRNA encapsulation, bioconjugation, and tangential flow filtration, and scale up these unit operations to commercial manufacturing batch size

Highly autonomous and productive in performing laboratory research or method development, requiring only minimal direction from or interaction with supervisor.

May initiate new areas of investigation that are scientifically meaningful, reliable, and can be incorporated directly into a research or development program.

Demonstrates high proficiency across a wide range of technologies relevant to tLNP process development.

Formulate conclusions and design follow-on experiments based on multidisciplinary data.

Primary author of publications, presentations, regulatory documents and/or primary inventor of patents.

Understand and adhere to corporate standards regarding code of conduct, safety, appropriate handling of materials, and GMP compliance.

Scientist I:
Trained in chemistry, colloidal science, or a related field. BS with 5+ years' or MS with 2+ years' industry experience. PhDs need not apply.

Scientist II:
Trained in chemistry, colloidal science, or a related field. BS with 7+ years' or MS with 5+ years' industry experience. PhDs need not apply.

Industry experience in tLNP process development (mRNA encapsulation, conjugation, ultrafiltration/diafiltration) is highly preferred.

For mRNA encapsulation, experience with systems other than microfluidics, such as impinging jet, coaxial jet, or multi-inlet vortex mixer is required.

Experience scaling up LNP processes to gram-scale mRNA or above is highly preferred.

Possess thorough theoretical and practical understanding of mRNA encapsulation

Experience with bioconjugation is a plus

Experience with lipid chemistry is a plus

Demonstrated ability to independently design, execute, and interpret critical experiments to answer scientific questions

Demonstrated ability to learn, understand, and master new experimental techniques

Ability to multitask and work within timelines

Demonstrated scientific writing skills and strong verbal communication skills
