What if… you could pioneer a new approach to designing life’s most essential molecules?

FL116, backed by Flagship Pioneering, is an early-stage biotechnology company transforming the way biomolecules are synthesized. Our innovative platform has the potential to redefine how critical research, diagnostic, and therapeutic molecules are designed and built. We are seeking passionate problem solvers ready to make a profound impact on biotechnology and therapeutic innovation.

Position Summary

We are seeking a highly motivated and exceptionally organized Research Associate II to expand our protein production capabilities across two complementary scales: bulk expression and purification of individual high-priority targets, and high-throughput parallel production of large variant panels. This hands-on, laboratory-facing role will execute and advance scalable protein expression, purification, normalization, and characterization workflows that feed the design–build–test cycles at the core of our platform.

The successful candidate will bring direct, practical experience in recombinant protein production and chromatographic purification at both preparative and high-throughput scale — together...
