Job Description

About NATi:

The Nucleic Acid Therapeutics Initiative (NATi), hosted by A*STAR, is Singapore’s national platform dedicated to advancing RNA-based medicines and revolutionizing drug and vaccine development. NATi’s mission is to establish Singapore as a globally recognized hub of excellence in nucleic acid therapeutics research, clinical translation, and commercialization.

NATi focuses on key RNA modalities such as antisense oligonucleotide (ASO), small interfering RNA (siRNA), and messenger RNA (mRNA). To drive this vision, NATi is building a biotech-like translational engine focused on asset and technology development spanning discovery to clinical development.

We are actively seeking passionate and committed computational RNA scientists with deep translational expertise to join us in advancing the next generation of RNA-based therapeutics.

Position Overview

We are seeking a highly skilled and results oriented Computational Scientist to develop computational pipelines and predictive drug property models for the rational design of ASOs, siRNAs and mRNAs across multiple therapeutic applications. This role is central to NATi’s strategy to build a differentiated RNA therapeutic platform through computational innovation, enabling rapid design and optimization of oligonucleotide and mRNA candidates with translational potential. The successful candidate will establish and scale bioinformatics and AI/ML capabilities to accelerate oligonucleotide and mRNA drug development, enhance predictive modelling, and explore novel chemical space in oligonucleotide and mRNA design. The selected candidate will work closely with cross-functional teams to translate computational insights into experimentally validated oligonucleotide candidates and contribute to NATi’s platform innovation and IP portfolio.

Key Responsibilities

• Drive RNA therapeutic design and computational optimisation, integrating RNA biology, transcript structure, RNA accessibility, and oligonucleotide chemistry, establishing and scaling computational pipelines to support rapid design and optimisation at scale.
• Develop automated data processing and visualization pipelines to support drug property analyses, including target specificity, cross-species targeting, and pharmacological properties.
• Develop and apply AI/ML frameworks to explore novel chemical space and to predict oligonucleotide drug properties, e.g. efficacy and toxicity, across diverse RNA targets.
• Analyze large biological datasets (e.g., transcriptomics, miRNA profiles, structural data) to inform oligonucleotide design and modification strategies.
• Develop models that integrate sequence, secondary/tertiary structure, and oligonucleotide chemistry to predict target engagement and guide binding assay design.
• Collaborate with oligonucleotide chemists, molecular biologists, and pharmacologists to translate computational predictions into experimentally validated oligonucleotide candidates, driving iterative design–test–learn cycles towards the identification of a drug candidate.
• Stay current with emerging computational tools, algorithms, and scientific literature relevant to the development of differentiated RNA therapeutics.
• Contribute to NATi’s intellectual property (IP) portfolio through computational tools and novel drug candidates.
• Prepare appropriate summary reports and presentations to update NATi’s leadership and stakeholders.

Qualifications & Experience

• Ph.D. in Computational Chemistry, Biophysics, Bioinformatics, Biomedical Engineering, or a related field.
• Minimum of 4 (Scientist) or 8 (Senior Scientist) years of hands-on industry experience in computational oligonucleotide design or RNA-targeting therapeutics.
• Strong computational skills, including hands-on experience developing scripts or workflows in R or Python, and applying machine learning frameworks to biological/chemical datasets, and familiarity with scientific computing libraries, git, and reproducible research practices.
• Proficiency in RNA structure prediction and interaction modelling tools (e.g., RNAstructure, ViennaRNA, IntaRNA, RNAhybrid).
• Hands-on experience with RNA-seq and sequence analysis tools and oligonucleotide design platforms.
• Strong understanding of RNA biology, including alternative splicing, polyadenylation, RNA editing, and RNA-binding proteins.
• Experience with nucleotide modification strategies (e.g., 2'-O-methyl, phosphorothioate, LNA) and their integration into computational design workflows to optimize oligonucleotide performance, spanning early design through late-stage candidate selection with strong understanding of risk assessment across discovery and development stages.
• Demonstrated experience combining physics-based modelling with AI/ML models to predict oligonucleotide efficacy, off-target effects, and/or RNA structure-function relationships using biological datasets is a plus.
• Proven ability to work independently and collaboratively in cross-functional, multidisciplinary teams, effectively communicating computational insights to experimental scientists.
• Demonstrated ability to troubleshoot complex scientific problems and adapt to shifting priorities in a fast-paced, quality-driven environment.
