  • Prepare and verify inoculum from master or working cell banks (MCB/WCB), including thawing cryopreserved cells, viability assessment, dilution, and transfer steps under sterile conditions while maintaining chain-of-custody documentation.
  • Operate and inoculate bioreactors, seed trains, shake flasks, and fermenters of varying scales; set up, monitor, and make controlled adjustments to agitation, temperature, pH and dissolved oxygen within defined process parameters.
  • Maintain strict aseptic gowning and cleanroom behavior in classified environments (ISO 5–8), perform aseptic transfers, and continuously practice contamination prevention techniques to meet environmental and sterility requirements.
  • Complete accurate, contemporaneous, and legible batch records, run logs, and production documentation (electronic or paper), capturing critical parameters, deviations, and in-process sampling events for GMP compliance.
  • Collect, label, and deliver in-process and final product samples for quality control testing (sterility, mycoplasma, endotoxin, cell viability) following chain-of-custody and sample handling SOPs.
  • Perform environmental monitoring (EM) activities such as settle plates, active air sampling, and surface sampling within the production area and interpret trends in collaboration with Quality Assurance to mitigate contamination risk.
  • Conduct setup, sterilization (SIP/CIP) verification, and integrity checks for single-use assemblies, glassware, and bioprocess equipment; escalate and document equipment anomalies and support preventive maintenance activities.
  • Execute aseptic fills, transfers, and closures within isolators or RABS, including connector transfers, luer operations, and needle/syringe manipulations, ensuring alignment with product-specific handling instructions.
  • Adhere to and support all cGMP, biosafety (BSL), and institutional safety protocols, including hazardous material handling, waste segregation, and spill response procedures to maintain a safe manufacturing environment.
  • Identify, investigate, and document non-conformances and process deviations; participate in root cause analysis and CAPA execution with cross-functional teams to prevent recurrence of contamination or process failures.
  • Train, mentor, and qualify new inoculation personnel on aseptic technique, SOPs, gowning, and batch execution; maintain operator competency matrices and assist with periodic requalification exercises.
  • Coordinate with upstream and downstream teams (process engineers, QC, QA, supply chain) to ensure materials, media, and seed lots are prepared and available on schedule to meet production timelines.
  • Review and reconcile inventory of media, reagents, disposables, and single-use components; perform cycle counts, lot verifications, and proper quarantine/release handling to prevent use of expired or out-of-spec materials.
  • Support tech transfer and scale-up activities by executing inoculation steps according to new scale-specific procedures and documenting any observed differences in performance or handling.
  • Execute changeover and cleanroom turnover procedures to transition between production campaigns while documenting sanitation and decontamination steps per validation requirements.
  • Run routine process checks and basic troubleshooting for inoculation-related hardware (pumps, sterile connectors, filtration assemblies); escalate complex mechanical issues to engineering while documenting interim containment measures.
  • Participate in internal and external audits, regulatory inspections, and supplier audits as a subject matter expert on inoculation practices and production documentation; provide data and operational descriptions as requested by QA and regulatory teams.
  • Implement continuous improvement initiatives targeted at reducing contamination rates, optimizing inoculation throughput, and increasing reproducibility—lead or contribute to lean activities and process mapping.
  • Maintain and input accurate process data into manufacturing execution systems (MES), electronic batch records (EBR), or LIMS; ensure data integrity and support data review activities by QA.
  • Prepare and sterilize media and buffer components as required for inoculation steps; verify pH, osmolarity, and sterility attributes prior to use and document findings.
  • Ensure proper cold chain handling for biological reagents and inocula (liquid nitrogen, -80°C storage), perform controlled thaw operations, and document temperature excursion events per established procedures.
  • Support product release activities by providing production records, deviation narratives, and in-process test results to Quality for final batch disposition.
  • Participate in cross-functional process development or troubleshooting experiments to optimize inoculation timing, seed density, and culture health metrics that impact overall yield and product quality.

Secondary Functions

  • Assist with scheduled environmental cleaning, gowning audits, and contamination control rounds to uphold manufacturing hygiene standards.
  • Support ad-hoc sampling for stability, release testing, and environmental investigations when QA or QC requests additional material.
  • Help maintain calibration and maintenance logs for inoculation-related equipment, coordinating with facilities and validation teams to schedule routine service.
  • Contribute to the generation and review of SOPs, work instructions, and training materials; propose edits based on practical operator experience and process improvement opportunities.
  • Participate in daily production huddles and shift handovers to communicate batch status, known issues, and upcoming inoculation activities to ensure seamless shift transitions.
  • Assist Quality Assurance with document control tasks, batch record archiving, and audit response compilation related to inoculation activities.
  • Support supply chain coordination by notifying procurement of low stock for critical single-use components or media needs to minimize production downtime.
  • Engage in periodic competency testing and simulated aseptic practice runs to validate operator readiness for high-risk inoculation steps.
  • Provide on-the-floor coaching during scale-up runs or process changes to ensure operators follow new procedures accurately.
  • Aid research and development with small-scale inoculation modeling or feasibility work that can be translated into production processes.
