Primary Responsibilities Include:

  • Independently perform solid phase synthesis of oligonucleotides with diverse sugar and backbone modifications at various scales
  • Troubleshoot and optimize synthesis methods to produce high quality oligonucleotides of various lengths
  • Perform purification (anion exchange, reverse phase), analysis (HPLC/UPLC), characterization (LCMS, UV, melting temperature) of oligonucleotides and their conjugates
  • Explore novel chemistries and designs to improve the DMPK and safety properties of oligonucleotides
  • Manage hit-to-lead optimization process and deliverables
  • Interact with the biology and preclinical groups to deliver clinical candidates
  • Multi-task across several projects and manage time effectively to achieve results
  • Collect, present, and discuss data at internal team meetings

Education and Skills Requirements:

  • PhD in chemistry or related discipline with a minimum of 4 years of experience in oligonucleotide synthesis -prior postdoctoral experience is preferred- or MSc with at least 7 years of industrial experience in the biotechnology industry
  • Strong experience with the operation of oligonucleotide synthesis machinery (Mermade), and AKTA purification unit
  • Working knowledge of RNA biology to enable collaboration across functions
  • Experience with ASO, siRNA or other DNA/RNA targeting modalities
  • Experience in nucleoside chemistry and bioconjugation are a plus
