Postdoctoral Fellowship: Postdoc in Biosensor & Microbial Detection — Singapore Institute of Technology

Original title: Research Fellow / Research Engineer (Biosensor and microbial detection) – JP2

About the role

The Singapore Institute of Technology (SIT) is a University of Applied Learning that works closely with industry in its research pursuits. Research staff have the opportunity to develop applied research skill sets relevant to industry demands while contributing to SIT projects.

This Research Fellow / Research Engineer position is part of a research team developing molecular and sequencing workflows for microbial characterization. The work supports the rapid detection of microbial bioburden in biopharmaceutical cleaning validation using a Surface-Enhanced Raman Spectroscopy (SERS) biosensor platform. Responsibilities focus on next-generation sequencing (NGS), qPCR-based molecular assays for microbial quantification and aptamer validation, and experimental support for aptamer discovery targeting environmental microorganisms listed in the US Pharmacopeia.

This fixed-term research role sits within the Food, Chemical and Biotechnology division. The posting start date is 17 March 2026.

Key responsibilities

Technical responsibilities

• Perform microbial community characterisation using next-generation sequencing (NGS) platforms such as Illumina or Oxford Nanopore sequencing.
• Design and perform qPCR-based molecular assays for microbial quantification and aptamer validation.
• Prepare DNA sequencing libraries, including nucleic acid extraction, amplification, and library preparation.
• Conduct basic bioinformatics processing of sequencing data, including sequence quality control and taxonomic profiling where required.
• Support aptamer discovery and validation experiments, including nucleic acid preparation, amplification, and molecular characterisation.
• Perform routine molecular biology techniques such as PCR, gel electrophoresis, DNA purification, and nucleic acid quantification.
• Maintain accurate laboratory records and experimental documentation.

Research and project responsibilities

• Plan and execute experimental workflows to support project milestones related to microbial detection and biosensor development.
• Contribute to sequencing-based microbial profiling of environmental and cleaning-validation samples.
• Collaborate with project investigators and interdisciplinary teams to integrate sequencing and molecular biology results with biosensor development.
• Prepare technical reports and contribute to scientific publications, presentations, and project documentation.
• Support generation of experimental data required for project validation and milestone reporting.

Operational and mentorship responsibilities

• Ensure laboratory compliance with Work Safety and Health (WSH) regulations and institutional safety guidelines.
• Manage procurement and inventory of molecular biology and sequencing consumables.
• Maintain laboratory equipment used for molecular biology and sequencing workflows.
• Support training of junior researchers, research assistants, and students where required.
• Contribute to knowledge sharing within the research group.
• Communicate with relevant internal and external stakeholders to ensure project deliverables are met.
• Perform any ad-hoc duties assigned by the Supervisor.

Job requirements
