Job Details

The Role:

Moderna is seeking a talented Scientist with experience in library screening and mammalian display to join our Infectious Disease Research team to support mRNA vaccine discovery and development at our Cambridge, MA facility.

The successful candidate will partner with a multidisciplinary team to develop internal capabilities and perform screens to discover and characterize antigen variants with improved surface expression and thermal stability. The goal is to use library construction and verification coupled with mammalian display to enable campaigns for multiple targets of interest. Successful lead generation will allow for subsequent testing in pre-clinical models and subsequently in the clinic. The position offers significant scientific growth opportunities in several areas including vaccine development, infectious disease biology, protein engineering and automation.

You will work in close collaboration with research leadership and a team of peers to identify and prioritize targets for screening. Success will require a collaborative and proactive approach with a clear focus on effective team work. Excellent laboratory and organizational skills combined with insightful and decisive data analysis will be required to ensure that program team deadlines are consistently reached. Presentation in program team and departmental meetings will be required to communicate results and recommendations to stakeholders. Further responsibilities include report and protocol writing, reagent generation and archiving, equipment onboarding, inventory maintenance and data archiving (ELN/LIMS).

Experience with both library screening and mammalian display are essential and ideally include: molecular biology methods for multiple library generation strategies (including key PCR methods for library construction in addition to rigorous cloning methods for efficient vector library assembly and verification), lentivirus production and transduction, mammalian cell culture, FACS and NGS sequencing methods and associated data analysis techniques. Additional skills to support downstream characterization as needed would be beneficial and could include: protein expression and purification using FPLC systems and biophysical characterization methods (SEC-MALS, DSF, and biosensor techniques including BLI and SPR. Experience with (or interest in) automation, high-throughput systems and associated data processing tools will be an added advantage.

Heres What Youll Do:

  • Collaborate with bioinformatics team to translate library design concepts into experimental strategy with associated timelines.

  • Collaborate with wet lab team members to further develop screening strategy and assign responsibilities to ensure timely progress balanced with other activities.

  • Perform library generation and cloning, initial pilot experiments to demonstrate library activity and parameters for screening, perform screening, use FACS to isolate clones with improved expression, prepare DNA samples for NGS, coordinate with NGS team to acquire and analyze data, archive all data in accessible formats.

  • Collaborate with manager to integrate experimental design and outcomes for presentation to team and program members, make recommendations based on data and program team feedback.

  • Develop approaches for assay miniaturization and automation for increased throughput.

  • Collaborate with team members to assist in building an integrated informatics solution with a vision of an end-to-end reagent-to-data pipeline.

  • Utilize an ELN to capture experimental results and participate in LIMS integration.

  • Assist in reagent ordering and inventory in addition to procurement and maintenance of laboratory equipment.

Heres What Youll Bring to the Table:

  • Exceptional Ph.D. in immunology, bacteriology, virology, biochemistry or biophysics ideally with industry experience.

  • Outstanding laboratory experience and knowledge in various library screening workflows, experimental design, data analysis and ability to transition hypotheses into data and scientific insights.

  • Knowledge of mRNA biotechnology, bacteriology, virology, immunology, protein structure and vaccine design is a plus.

  • Experience in automation is an advantage.

  • Candidates will be curious in exploring new paths for drug discovery, bold in proposing creative experimental designs and ideas, will work collaboratively with multifunctional teams and be relentless in pursuing successful outcomes.

  • Candidates must possess excellent data management and verbal/written communication skills, have excellent track record in experimental performance, evaluate and process data, present results in a clear, concise and timely manner, and assist with the preparation of final written reports.

  • Ability to work independently and as part of a team in a highly dynamic, fast-paced, matrixed environment with evolving priorities.

  • Ability to collaborate with colleagues to achieve scientific and career goals aligned with business objectives.
