Job Summary

We are seeking a highly motivated researcher to fill a Co-op position on our Synthetic Biology team, supporting the design, production, and in vitro testing of mRNA therapeutics. This is a hands-on, bench-based role: you will work with mammalian cell lines every day, transfect and test mRNAs, and support DNA template and mRNA production, while learning cutting-edge mRNA and synthetic biology technologies as an integral member of the team. You will perform experimental research, document it, and present your results.

Key Responsibilities

Maintain human and murine cell lines: sterile technique, passaging, cell counting and viability, cryopreservation

Transfect IVT mRNAs and LNP-formulated mRNAs into mammalian cells and quantify expression by flow cytometry

Support DNA template design and construction (primer design, PCR, DNA assembly, plasmid prep and QC)

Support internal mRNA production and quality analysis (IVT, purification, Nanodrop/Bioanalyzer)

Execute, document (electronic lab notebook), and present experiments; learn to work with minimal supervision and generate decision-making data

Qualifications

B.S. or M.S. student in Biology, Biological Engineering, Molecular Biology, Biochemistry, or a related field

Required: hands-on mammalian cell culture experience at the bench (sterile technique, passaging, transfection, viability assays), not coursework alone

≥6 months of previous laboratory experience strongly preferred

Experience with molecular biology techniques (PCR, cloning, gel electrophoresis) and/or assays such as flow cytometry is a plus

Reliable, detail-oriented, and able to work full-time (35-40 hours/week) on site in Boston's Seaport throughout the ≥6-month Co-op

Eagerness to grow and develop as a scientist

Benefits

Compensation: $20-25/hour based on experience

Free Bluebikes membership

Gym membership support
