Core Responsibilities

Primary Functions

Execute aseptic setup, gowning, and entry procedures for ISO 5/7/8 cleanrooms and isolators, ensuring strict compliance with gowning matrices, laminar flow patterns, and pressure differentials to prevent contamination of sterile product.
Operate, monitor and perform changeovers on fill-finish equipment including vial/syringe/ampoule filling machines, isolators, sterile connectors, stoppering and crimping systems while adhering to validated procedures and equipment operating limits.
Perform in-process checks and critical control point verifications during sterile operations (e.g., fill weights, visual inspection, container closure integrity checks, particle counts) and take immediate corrective action or pause production when specifications are not met.
Complete accurate, legible and timely batch records and production documentation per cGMP requirements; ensure all deviations, observations and line events are documented and escalated to QA for review.
Conduct environmental monitoring activities including active and passive air sampling, surface and personnel monitoring, and timely logging of microbial and particle results; respond to excursion events and support follow-up investigations.
Execute and support routine cleaning and sanitization of cleanrooms, isolators and critical utilities using approved disinfectants and validated contact times while following aseptic cleaning procedures and changeover checklists.
Prepare and transfer sterile components and materials using controlled transfer systems and pass-throughs, verifying tamper-evident seals, sterilization indicators and material release documentation prior to entry into sterile areas.
Participate in and execute media fill simulations and sterile process validations; follow validation scripts, record results, and participate in analysis of contamination sources if media fills fail acceptance criteria.
Perform pre-use inspections and checks on sterile equipment, HEPA filters, laminar flow hoods and isolator glove integrity tests; report and tag non-conforming equipment for maintenance or calibration.
Execute gowning qualification and ongoing competency assessments for production staff, provide feedback on aseptic technique, and coach team members to maintain sterile technique standards.
Support root cause analysis for contamination events, non-conformances and deviations by collecting data, documenting observed conditions, participating in investigations and helping implement corrective and preventive actions (CAPAs).
Follow and enforce contamination control policies including traffic patterns, material segregation, personnel behavior, and cleaning frequency to maintain environmental control in sterile suites.
Assist with routine maintenance, calibration verifications and minor troubleshooting of filling lines, isolators, and sterilization equipment; coordinate with Engineering and Maintenance for complex repairs or validations.
Perform container and label inspections, visual defect detection and in-process sampling for QC testing; segregate and label suspect or out-of-specification product according to procedure.
Support aseptic transfers and sterile filtration processes, ensuring filter integrity tests and sterile filter changeover procedures are completed and documented.
Participate in internal and external audits by preparing records, explaining aseptic processes, demonstrating gowning and cleanroom behavior, and implementing audit findings under QA direction.
Apply sterility assurance principles to day-to-day work: validate aseptic process conditions, maintain controlled documentation, and escalate issues that could impact product sterility or patient safety.
Execute lot release support activities such as collecting samples for QC testing, verifying stability and storage conditions, and assisting QA with product disposition documentation.
Follow biosafety, hazardous materials and waste handling procedures when dealing with biological materials, including proper segregation, containment and disposal of contaminated consumables.
Engage in continuous improvement projects (5S, root cause reduction, process optimization) to reduce contamination risk, increase yield and improve operational efficiency in the sterile manufacturing environment.
Train and onboard new operators on aseptic operations, gowning practices, SOP usage and safety protocols; maintain training records and competency assessments to ensure qualification status is current.
Maintain strict adherence to cGMP, USP <797>/<800> where applicable, company SOPs and safety policies; proactively identify process improvements and compliance gaps and work with QA/Validation to close them.
Support batch release and post-production activities such as root-cause documentation, trending of environmental and process data, and communication with cross-functional teams to facilitate timely product release.

Secondary Functions

Collaborate with Quality Assurance and Microbiology to schedule and execute corrective action plans resulting from environmental excursions or media fill failures.
Participate in cross-functional continuous improvement teams to optimize changeover routines, reduce downtime and improve contamination-control workflows.
Support documentation audits and electronic batch record (EBR) system improvements by providing practical operator input and testing new templates or controls.
Assist with inventory control for sterile consumables (filters, gloves, gowns, disinfectants) to ensure availability and traceability of critical supplies.
Provide input to risk assessments (e.g., FMEA) and sterile process change controls to evaluate impact on sterility, product quality and regulatory compliance.
