🎯 Role Definition

A Bench Scientist is a hands-on laboratory professional responsible for planning, executing and documenting experimental work across molecular biology, biochemistry and cell biology workflows. This role focuses on accurate experimental technique, reproducible assay execution, troubleshooting, instrument maintenance and clear technical reporting. Bench Scientists work closely with research scientists, project managers and quality teams to translate study goals into reliable laboratory results, comply with GLP/GMP and support product development, discovery or manufacturing activities. Strong technical skills (cell culture, PCR/qPCR, ELISA, western blot, flow cytometry), good laboratory practice, and meticulous record-keeping are essential.

Core Responsibilities

Primary Functions

  • Design and execute laboratory experiments and assays (molecular biology, protein biochemistry, cell biology) according to project plans and SOPs, ensuring reproducible results and adherence to timelines.
  • Perform routine and advanced cell culture work, including maintenance of cell lines, mycoplasma testing, transfections, differentiation protocols and aseptic technique to support in vitro studies.
  • Run and interpret PCR and qPCR assays for gene expression, genotyping and pathogen detection; prepare reaction mixes, optimize primer/probe conditions and analyze Ct values with appropriate software.
  • Conduct immunoassays such as ELISA, MSD or bead-based multiplex assays to quantify proteins, cytokines and biomarkers; prepare standards, controls, and analyze dose–response curves.
  • Execute electrophoresis and western blotting workflows for protein detection: sample prep, SDS-PAGE, transfer, blocking, antibody incubations and chemiluminescent/fluorescent detection with quantitative interpretation.
  • Operate and maintain flow cytometers for phenotyping, cell cycle or apoptosis assays; prepare samples, perform compensation, acquire data and analyze with FlowJo or equivalent software.
  • Prepare samples and run chromatographic analyses (HPLC/UPLC) and basic mass spectrometry sample prep protocols when applicable; support analytical method execution and troubleshooting.
  • Develop, optimize and transfer laboratory methods and protocols; perform method qualification/validation in accordance with GLP/GMP guidelines and laboratory quality systems.
  • Maintain detailed experimental records in electronic lab notebooks (ELN) or paper notebooks, ensuring traceability, raw data integrity and compliance with audit requirements.
  • Calibrate, operate and perform routine maintenance on laboratory instruments (centrifuges, incubators, biosafety cabinets, PCR machines, plate readers); coordinate repairs with vendors and maintain service logs.
  • Prepare reagents, buffers and media at scale, perform quality checks, label and track lots to support consistent experimental performance across projects.
  • Execute sample handling workflows: accessioning, aliquoting, storage management (freezers, LN2), chain-of-custody documentation and appropriate sample disposal.
  • Analyze experimental data using statistical tools and software (Excel, Prism, R or Python basics), summarize results, generate figures and provide technical interpretation to support decision-making.
  • Troubleshoot experimental failures and instrument issues by systematically investigating root causes, proposing corrective actions and documenting outcomes to improve reproducibility.
  • Participate in cross-functional project meetings, present experimental progress, align on next steps with project managers, and prioritize tasks to meet milestone-driven deliverables.
  • Enforce laboratory safety and compliance standards (PPE, chemical and biological hazard handling, waste management), participate in safety training and maintain a culture of safety-first practices.
  • Assist in preparation of technical reports, study summaries, methods sections and standard operating procedures (SOPs) for internal use or regulatory submissions.
  • Train and mentor junior technicians and interns on laboratory techniques, data integrity, good documentation practices and lab safety to build team capability.
  • Support inventory management: forecast reagent and consumable needs, place purchase orders, receive supplies, and maintain accurate stock records to minimize downtime.
  • Contribute to continuous improvement initiatives: implement best practices, improve workflows, standardize procedures and support quality improvement projects.
  • Participate in internal audits and external inspections by providing documentation, demonstrating procedures and implementing corrective actions when required.
  • Maintain confidentiality of proprietary protocols, experimental designs and data; comply with intellectual property and data management policies.

Secondary Functions

  • Assist with reagent qualification and supplier evaluations to ensure supply-chain robustness and reagent lot-to-lot consistency.
  • Support cross-training efforts and build redundancy for critical assays across the team to maintain operational resilience.
  • Help prepare material transfer documentation, sample kits and SOP packages for collaborative studies with external partners or CROs.
  • Collaborate with bioinformatics or data science colleagues for more complex data analysis, image quantification or high-content screening interpretation.
  • Participate in lab relocation or equipment installation projects, helping validate new workflows and perform acceptance testing.
  • Provide ad hoc support to QC/Manufacturing teams during scale-up, transfer, or troubleshooting activities as needed.
