  • Execute cryopreservation and storage of microbial and cell culture stocks using established freezing media and controlled-rate protocols; catalogue strain information and sample locations in inventory systems.
  • Monitor cultures for contamination, unexpected growth patterns, or phenotype changes; initiate containment and corrective actions per biosafety and quality procedures.
  • Follow BSL1/BSL2 biosafety practices, PPE requirements, and decontamination procedures; complete spill response and waste handling in alignment with institutional and regulatory policies.
  • Perform accurate lot, expiration, and traceability tracking for strains, media, and reagents; maintain chain-of-custody documentation for production or clinical samples.
  • Prepare inocula for pilot production, fermentation runs, or downstream processing by scaling cultures under controlled conditions and ensuring input quality metrics are met.
  • Receive and accession incoming samples and isolates; verify sample identity, labeling, documentation, and storage requirements prior to experimental processing.
  • Participate in daily and weekly environmental and process monitoring programs, collecting swabs and settle plates, and reporting results for contamination control activities.
  • Assist scientists and production staff by preparing starter cultures, working cell banks, and routine inoculation schedules to meet project timelines and manufacturing demands.
  • Support validation and qualification activities (equipment, processes, aseptic technique) by following test plans, documenting procedures, and compiling supporting evidence for audits.
  • Dispose of biohazardous waste and sharps in accordance with biohazard disposal protocols, hazardous waste regulations, and institutional policies, ensuring safe laboratory environment.
  • Communicate test progress, unexpected results, and sample status clearly to supervisors and cross-functional teams to support timely troubleshooting and decision-making.
  • Participate in training programs and competency assessments to maintain and demonstrate proficiency in aseptic technique, equipment use, and safety practices.
  • Maintain accurate, legible, and audit-ready records: logbooks, batch records, experimental notebooks, and LIMS entries, ensuring traceability for regulatory and quality requirements.
  • Support reagent and supply inventory management: track stock levels, assist with ordering, verify incoming shipments, and rotate per expiration and first-expire-first-out (FEFO) practices.
  • Contribute to continuous improvement efforts by suggesting workflow optimizations, documenting process deviations, and implementing corrective and preventive actions (CAPA) when required.
  • Prepare and sterilize glassware, flasks, and reusable labware; inspect consumables for defects and escalate quality concerns for contaminated or out-of-specification items.
  • Assist in preparing materials for microscopy, staining, and basic morphological analysis; capture and report observations relevant to culture health and experimental endpoints.
  • Support basic molecular workflows as needed, including sample aliquoting and preparation for downstream assays (PCR, sequencing), while maintaining separation between culture handling and molecular workflows to prevent cross-contamination.
  • Participate in night or weekend incubation checks and shift hand-offs to ensure uninterrupted culture monitoring in production or time-sensitive research projects.

Secondary Functions

  • Assist with data entry, basic charting of growth curves, and routine generation of lab reports for project leads or quality staff; ensure data accuracy and timely submission.
  • Participate in internal audits and support external inspections by preparing required documentation and facilitating access to records and equipment.
  • Contribute to SOP and work instruction updates by documenting observed improvements and helping to standardize best practices across shifts.
  • Support onboarding of new technicians by demonstrating aseptic technique, proper equipment operation, and documentation practices.
  • Help coordinate small-scale scheduling for incubator space and shared equipment to optimize lab throughput and reduce bottlenecks.
  • Engage in cross-functional troubleshooting with maintenance, quality, and R&D teams to rapidly identify and resolve process disruptions that impact inoculation workflows.
  • Participate in safety committees or team meetings to communicate biosafety trends and recommend changes to minimize contamination risk.
