Key Responsibilities

  • Establish, optimise, and scale high-throughput SPOS workflows for small- and mid-scale synthesis of ASOs, siRNA, SSO, RNA editors, and emerging constructs including non-canonical chemistries and next-generation amidites
  • Expand oligonucleotide platform capabilities beyond established modalities by evaluating, integrating, and validating new chemistries, scaffolds, conjugation strategies, and delivery-enabled formats
  • Develop and maintain standard operating procedures (SOPs) for synthesis, processing, purification, and analytical characterisation to ensure high-quality and reproducible results
  • Build, mentor, and manage a high-performing team of research associates and scientists; coach junior scientists across levels on experimental design, execution, data interpretation, and scientific thinking
  • Serve as Lead Oligonucleotide Chemist on multidisciplinary project teams with responsibility for oligo design, synthesis strategy, manufacturability assessment, and optimisation toward drug candidate nomination
  • Collaborate closely with bioconjugation chemists to develop a seamless workflow for generation of conjugated oligonucleotides (e.g., peptides, antibodies, lipids, sugars) for in vitro/in vivo studies
  • Strategically leverage CRO partners for routine, non-IP-sensitive activities, while maintaining core IP-generating chemistry and novel construct design in-house
  • Play a key role in expanding NATi's intellectual property (IP) portfolio through generation of new chemical compositions and drug candidates; support IP filing by preparing technical documentation, coordinating patent submission, and collaborating with legal teams to safeguard proprietary technologies
  • Prepare appropriate summary reports and presentations to update NATi leadership and stakeholders

Requirements

  • A doctorate degree in Chemistry, Chemical Biology, Organic/Medicinal Chemistry, or a related field
  • A minimum of 7+ (Senior Scientist), 10+ (Principal Scientist), 13+ (Associate Director) years of hands-on modern synthetic chemistry methods particularly in nucleosides, nucleotides, and oligonucleotide synthesis, purification, and analysis in pharmaceutical or biotechnology settings
  • Extensive hands-on experience with modern SPOS instrumentation (e.g., MerMade 192X/12, ÄKTA OligoSynth), purification systems (e.g., ÄKTA Avant/Pure, tangential flow filtration), and analytical platforms (e.g., UPLC, LC/MS, HRMS), and lyophilisers
  • Demonstrated ability to build or expand oligonucleotide chemistry capabilities, integrate emerging chemistries, and develop robust platform workflows
  • Experience managing or collaborating with CROs, including tech transfer, oversight, and governance of outsourced synthesis or analysis activities
  • Proven track record in advancing oligonucleotide-based therapeutics toward candidate selection, supported by publications, patents, IND filings, or other notable scientific disclosures
  • Strong leadership, mentorship, and communication skills with the ability to guide junior scientists and influence cross-functional teams
  • Ability to thrive in a fast-paced, translational environment with shifting priorities and demanding objectives
  • Prior experience in therapeutic oligonucleotide discovery for metabolic, cardiovascular, muscle, or retinal diseases is highly desirable
  • Possess and/or develop robust understanding in cardiovascular, metabolic, muscle and/or ophthalmological disorders
