Principal Scientist – Director, Oligonucleotide Therapeutics Discovery & Development

◔ Full-Time
➣ Location: BioBAY, Suzhou
☉ Middle-Senior Level

Responsibilities:

  • Oligonucleotide Design & Optimization: Design, synthesize, and screen siRNA/ASO sequences to optimize target binding affinity, potency, stability, and specificity.
  • In Vitro Characterization: Develop and validate cell-based assays to assess siRNA/ASO activity: siRNA knockdown efficiency, ASO-mediated mRNA degradation/splicing modulation, off-target effects, cytotoxicity, and cellular uptake.
  • Delivery System Development: Collaborate with internal or external teams to design, optimize, and characterize delivery platforms for siRNA/ASO, including antibody conjugates, lipid nanoparticles (LNPs), and other targeted delivery systems in vitro/in vivo delivery efficacy.
  • Preclinical In Vivo Studies: Plan and execute preclinical studies in rodent/non-rodent models to assess siRNA/ASO Tissue-specific targeting and biodistribution, Pharmacokinetics, Pharmacodynamics, Efficacy, and Safety.
  • Technology Innovation & Trend Monitoring: Stay updated on the latest advancements in oligonucleotide therapeutics (siRNA/ASO design, chemical modifications, delivery technologies) and propose innovative strategies to address program challenges (e.g., reduced off-target effects).

Qualifications:

  • PhD in Molecular Biology, Biochemistry, Pharmacology, Organic Chemistry (Nucleic Acid Focus), Biotechnology, or a related field; or Master’s degree with 3+ years of hands-on industry experience in siRNA/ASO/AOC drug development.
  • Experience with siRNA or ASO modality: proven track record in oligonucleotide design, synthesis, in vitro characterization (cell culture, transfection, qPCR, Western blot), and in vivo preclinical studies.
  • Experience in siRNA/ASO delivery systems (LNPs, GalNAc conjugates, or peptide conjugates) is preferred.
  • Familiarity with preclinical drug development processes, including PK/PD analysis, efficacy model design, safety assessment, and IND-enabling studies.
  • Ability to work independently and collaboratively in a fast-paced, cross-functional team environment.
  • Experience in advancing siRNA/ASO programs to IND-enabling stages in a specific therapeutic area (e.g., neurodegeneration, rare genetic diseases, oncology, metabolic disorders) is highly preferred.
  • Proficient in applying AI tools in daily works
