As Head of Chemistry, you will work closely with Ansa’s enzyme engineering team to develop new nucleoside triphosphates and linkers for Ansa’s enzymatic DNA synthesis technology. You will be responsible for designing synthesis plans for novel nucleoside triphosphates that can be tethered to a protein via a cleavable linker, coordinating synthesis of key intermediates at CROs, performing final synthesis steps in-house, analyzing the stability and purity of linkers and nucleotides, identifying and eliminating trace impurities, and giving feedback to the team to ensure that project deliverables are met.
