Job description

DNA Script

DNA Script is a leading company in manufacturing de novo synthetic nucleic acids using enzymatic DNA synthesis (EDS) technology. The company aims at accelerating innovation in life science and technology through the decentralization of rapid, on demand and high-quality DNA synthesis. DNA Script's approach leverages nature's billions of years of evolution in synthesizing DNA to set a new standard for customizing nucleic acid synthesis thus accelerating discovery in genetics, genomics, and synthetic biology. Discovery disciplines with profound impacts upon humanity such as biopharma, translational genetics and even molecular information storage all start with synthetic DNA. The company has recently initiated the commercialization of its first EDS powered platform, the SYNTAX system.

To date, DNA Script has raised over $315M of financing, with leading investors such as Coatue Management, Fidelity Management and Research, Catalio Capital Management, Casdin Capital, LSP, Bpifrance Large Ventures, Danaher, Illumina Ventures, Agilent, Merck Ventures, Sofinnova Partners, Kurma Partners, T Rowe Price, Baillie Gifford and Eurazeo.

DNA Script also partners on technology and product development with leading organizations such as DARPA, IARPA, Moderna Therapeutics, GE Research, Illumina, the Broad Institute, Harvard University, Institut Pasteur and the French Department of Defense.

DNA Script has its research and manufacturing facilities headquartered in Paris, France, and is in the process of expanding its commercial and development teams in Daly City.
