Develop, optimise and validate laboratory protocols for molecular techniques—ensuring reproducible results, high throughput capacity and alignment with project goals.
Prepare biological samples including extraction of nucleic acids (DNA/RNA), proteins or other biomolecules, perform quantification, purification, library preparation and downstream analysis.
Conduct data analysis and interpretation of molecular results (e.g., sequence alignments, variant calling, expression profiling, proteomic analyses) and translate findings into actionable insights.
Collaborate with bioinformatics, computational biology and engineering teams to integrate molecular data, develop models, visualise results and inform experimental or product strategy.
Maintain and calibrate molecular biology instrumentation (PCR machines, sequencers, electrophoresis systems, spectrophotometers), monitor performance, troubleshoot equipment and manage maintenance logs.
Document experiments, maintain laboratory notebooks or electronic records (ELN), follow good laboratory practice (GLP), ensure data integrity, version control and reproducibility of molecular workflows.
Participate in method development, validation or transfer of molecular assays (diagnostics, research tools, production systems), define performance criteria, document results and support regulatory readiness.
Publish and present scientific findings in peer‑reviewed journals or conferences, prepare technical reports, posters or internal communications to share research outcomes.
Stay current with technological advances in molecular biology, genomics, single‑cell techniques, synthetic biology or gene‑editing tools and propose their implementation in laboratory workflows.
Supervise, mentor or train junior scientists, lab technicians or students in molecular biology techniques, safety procedures and best practices.
Conduct quality control and assurance of molecular biology workflows, monitor contamination risks, ensure proper controls, manage reagent inventories and support accreditation or audit readiness.
Collaborate with cross‑functional teams (R&D, manufacturing, clinical, regulatory) to translate molecular biology findings into product development, diagnostics, therapeutics or agricultural biotech solutions.
Plan and conduct experiments to explore gene regulation, cell signalling, protein interactions or biomolecular pathways, develop hypotheses, controls and statistical analyses.
Manage budgets, order and maintain supplies, reagents and disposables, optimise resource usage and support laboratory operations efficiency.
Participate in grant writing or proposal preparation to secure funding for molecular biology projects, contribute to strategic planning of research programmes.
Perform risk assessments, biosafety procedures, chemical safety and compliance with institutional, national or international regulation for molecular biology labs.
Develop and apply molecular tools for diagnostic or therapeutic development—such as biomarker discovery, assay design or genetic modification of cells, plants or microorganisms.
Engage in interdisciplinary research involving molecular biology, bioengineering, cell biology or synthetic biology, and contribute to translating discovery into scalable systems.
Provide support for operational and secondary tasks such as sample logistics, data entry, ad‑hoc analyses, collaborative meetings, maintaining an organised lab environment and contributing to overall research strategy.

Secondary Functions

Support ad‑hoc data requests and exploratory data‑analysis of molecular data sets to inform decision‑making or support research pivots.
Contribute to the organisation’s molecular biology roadmap or strategy—identifying emerging methods, data‑infrastructure needs or collaborative opportunities and participating in project planning.
Collaborate with engineering or product teams to translate molecular biology insights into product specifications, software tools or delivery systems and participate in agile planning cycles where applicable.
