  • Maintain accurate experimental records (ELN or lab notebooks)
  • Use data analysis tools (Excel, JMP, Python, or similar) to interpret results
  • Prepare summaries, reports, and presentations of experimental findings

Equipment & Lab Maintenance
  • Maintain and calibrate fermentation and analytical equipment
  • Ensure proper cleaning, sterilization (CIP/SIP), and maintenance of bioreactors
  • Assist with installation and qualification of new equipment

Documentation & Compliance
  • Follow safety, quality, and regulatory guidelines (e.g., GMP where applicable)
  • Maintain SOPs and batch records
  • Support audits and documentation requirements

Cross-functional Collaboration
  • Work with molecular biology, downstream processing, and analytics teams
  • Support technology transfer to manufacturing teams
  • Communicate results effectively to internal stakeholders

Basic Qualifications
