Chroma Medicine is pioneering a new class of genomic medicines that harness epigenetics, nature’s innate mechanism for gene regulation, revolutionizing the treatment of genetically driven diseases. As a start-up genomic medicine company with world-leading scientific founders, strong investment backing including Newpath Partners and Atlas Venture, and experienced leadership, Chroma is positioned to be the leader in epigenetic editing.

The epigenome is nature’s gatekeeper for gene expression, governing cell phenotype and function by precisely controlling gene activity without changing the underlying DNA sequence. Building on groundbreaking research from the world’s foremost genomic medicine experts, Chroma Medicine is working at the cutting edge of precision genomics, building an entirely new class of therapeutics to achieve unparalleled control of gene expression.

We are hiring at our Boston, Massachusetts site, offering a unique opportunity to be part of our foundational Chroma team.


You will be responsible for developing and optimizing each segment of Chroma’s gram-scale mRNA production process.
