Scientist/Sr. Scientist, mRNA Display

Your new position As a Scientist or Senior Scientist in mRNA Display, you will play a central scientific role in our new Molecular Platform Development organization, driving peptide and mini-protein discovery through mRNA display technology. You will help build and operate a modern, high-throughput display platform at the inception of our new Cambridge, MA research center. This role suits a scientist with strong technical expertise across the full mRNA display workflow, scientific curiosity, and a desire to grow in scope and responsibility. We offer exciting responsibilities Execute the full peptide and mini-protein mRNA display workflow, from library design and in vitro transcription/translation through puromycin-based fusion, selection, and enrichment Apply expertise in non-canonical amino acid incorporation to expand chemical diversity within display libraries Apply chemical modification strategies—including macrocyclization/stapling, lipidation, and bioconjugation—to improve potency, stability, and pharmacokinetic properties Build and maintain custom cell-free display systems in-house, including establishing mRNA display platforms from scratch Generate and analyze structure-activity relationship (SAR) data to support optimization of selected hits, contributing to lead and backup candidate selection Collaborate with computational modeling, design, and data science colleagues to support efficient DMTA cycles Your profile You bring strong technical expertise across the peptide and mini-protein mRNA display workflow, along with scientific curiosity and sound judgment. You thrive in a collaborative, multidisciplinary environment and are motivated to help shape a new platform and research center from an early stage. You communicate scientific data and concepts clearly and work effectively across cross-functional project teams. PhD in Chemical Biology, Biochemistry, Organic Chemistry, or a related field preferred (postdoctoral training preferred); candidates with a BS/MS and significantly more relevant industry experience will also be considered 2+ years of relevant post-degree experience in mRNA display or related in vitro display technologies (Scientist); 4+ years (Senior Scientist) Experience building custom cell-free display systems from scratch strongly preferred; experience with other in vitro display technologies (e.g., ribosome display) and cell-free protein/peptide expression systems (e.g., IVTT, CFS) is a plus Experience incorporating non-canonical amino acids via reprogrammed translation systems (e.g., flexizyme-based methods) or related approaches Experience applying next-generation sequencing (NGS) to analyze library diversity and selection enrichment; familiarity with associated bioinformatics is a plus Familiarity with analytical characterization of peptides (e.g., LC-MS-based methods) and peptide developability considerations (stability, solubility, manufacturability) Your new team You will join Molecular Platform Development, a new organization created to strengthen and advance diverse drug modality capabilities in metabolic disease, based at our new Cambridge, MA research center. The site is a highly collaborative, multidisciplinary discovery hub integrating computational research, chemistry, and biology, and is deeply connected to the Greater Boston life sciences ecosystem.
