Establish and maintain robust aseptic technique, contamination control procedures and environmental monitoring during fermentation and downstream operations; lead contamination investigations and corrective actions for root cause identification and prevention.
Prepare and maintain accurate technical documentation including SOPs, batch records, protocol notebooks, experiment tracking in LIMS, and technical reports suitable for cross-functional review, regulatory submission or manufacturing transfer.
Conduct stability and formulation studies to define storage conditions, excipient compatibility and shelf-life for enzyme products; recommend formulation changes to improve activity retention and handling.
Work closely with Analytical Development and QC to transfer analytical methods, establish acceptance criteria, perform method qualification/validation and ensure data integrity for release testing and regulatory compliance.
Perform process risk assessments, scale-up assessments and manufacturability reviews to ensure successful tech transfer to pilot or manufacturing sites; collaborate with engineering on equipment selection, utilities and CIP/SIP requirements.
Troubleshoot process and analytical anomalies using root cause analysis (RCA), implement corrective and preventative actions (CAPA), and communicate technical findings and mitigation plans to stakeholders.
Drive continuous improvement efforts focused on yield improvement, cost reduction, reduced cycle times and increased process robustness through lean principles, workflow optimization and pilot testing.
Coordinate and mentor junior scientists, research associates and interns, including training on bioreactor operation, aseptic technique, analytical assays and safety protocols.
Ensure compliance with regulatory standards (cGMP where applicable), biosafety guidelines and internal quality policies during development and scale-up activities; lead documentation required for audits and inspections.
Collaborate with cross-functional teams (R&D, Manufacturing, QA/QC, Regulatory Affairs, Supply Chain) to align technical strategies, timelines and resource allocation for enzyme development projects.
Manage reagent and consumable inventory for fermentation and analytical labs; evaluate and qualify suppliers for critical raw materials such as media components, resins and reagents.
Evaluate emerging technologies and instrumentation for enzymology and fermentation (high-throughput screening, automation, real-time PAT sensors) and recommend pilot adoption to accelerate development timelines.
Prepare and present technical summaries, development plans and milestone updates for project teams and senior management; support budgeting and resource planning for enzymology projects.
