Production Microbiologist – Fermentation Biotechnology / Molecular Biology Key Responsibilities Microbiology & Cell Culture Operations
- Lead daily microbiology laboratory activities supporting commercial fermentation operations, including aseptic inoculation, propagation, and maintenance of bacterial cultures.
- Prepare and sterilize fermentation media, buffers, and process solutions.
- Perform microbial plating, contamination monitoring, Gram staining, microscopy, and morphology tracking.
- Develop and improve contamination detection workflows for bacterial, fungal, and bacteriophage identification in process streams and environmental samples.
- Maintain microbial culture collections, master cell banks, and working cell banks with validated traceability systems and electronic inventory management.
- Design and execute microbial engineering strategies to improve strain robustness, productivity, metabolic performance, and process consistency in industrial fermentation applications.
- Support development and optimization of molecular and biochemical assays including RT-PCR, ELISA, and other rapid diagnostic methods.
- Operate, troubleshoot, calibrate, and maintain analytical instrumentation including HPLC, carbohydrate analyzers, balances, shakers, and related laboratory equipment.
- Analyze fermentation and analytical datasets using statistical and data visualization tools to identify process trends and continuous improvement opportunities.
- Contribute to experimental design, DOE studies, root cause investigations, and technical reports.
- Identify continuous improvement opportunities focused on improving process efficiency, contamination reduction, uptime, cost reduction, and operational stability.
- Collaborate with other laboratory personnel and provide technical guidance on aseptic techniques, microbial operations, analytical methods, and data interpretation.
- Maintain and improve SOPs, batch records, and laboratory documentation systems in compliance with site and quality requirements.
- Provide on‑call technical support and troubleshooting for critical fermentation and microbiology operations as needed.
- Collaborate closely with the R&D Manager to execute and support fermentation process development initiatives focused on improving productivity, titer, yield, process robustness, and manufacturing reliability.
- Assist in execution, monitoring, and documentation of 15L fed‑batch aerobic fermentation experiments designed by the R&D Manager and broader Manufacturing Technology team.
- Support fermentation optimization activities.
- Work alongside Operations, Engineering, and the R&D Manager to troubleshoot fermentation process deviations, contamination events, and operational performance issues.
- Support scale‑up and scale‑down process evaluation efforts through laboratory experimentation, data collection, and process observation.
- Assist with update, implementation, and maintenance of process monitoring systems, historical data review, and automation tools used in fermentation operations.
- Contribute technical observations and recommendations during experimental reviews, process investigations, and continuous improvement discussions.
- Support development of standardized fermentation practices, process documentation, and knowledge transfer across R&D and manufacturing teams.
- Bachelor’s degree, Master’s degree, or PhD in Biotechnology, Molecular Biology, Microbiology, Biochemical Engineering, or related scientific discipline.
- 3+ years of experience in industrial biotechnology, fermentation process development, microbiology, or bioprocess R&D in a laboratory, manufacturing or pilot plant environment.
- Demonstrated experience operating and troubleshooting microbial growth systems, ideally fed‑batch aerobic bacterial fermentations.
- Fundamental understanding of fermentation scale‑up principles, process control strategies, and bioprocess analytics.
- Experience with molecular biology and contamination detection techniques including PCR, ELISA, and microbial identification methods.
- Strong analytical, statistical, and technical problem‑solving skills.
