Staff Software Systems Developer

Our mission at Ansa Biotechnologies is to revolutionize the way we make DNA. Compared to reading or editing life’s code, writing new code from scratch has remained one of the field’s most elusive challenges. At Ansa, we are putting nature to work, creating novel enzymatic solutions that will redefine how we build DNA. We believe that the biggest challenges our world faces will be solved using biotechnology and that DNA synthesis is the fuel for that transformation. Our enzyme-based approach (published in Nature Biotechnology) promises to dramatically accelerate innovation in biological research and biotechnology, including therapeutics, diagnostics, biomanufacturing, and synthetic biology. We look forward to our DNA products making an impact.
