Plant Bio-process Engineer
This role is for those who love applying engineering principles to biological systems, driven by the challenge of translating scientific discoveries into industrial-scale production. It requires a blend of analytical rigor, problem-solving prowess, and a keen eye for efficiency and safety. While the work can be demanding, especially during critical production phases, the satisfaction of seeing innovative bio-products come to life on a large scale is incredibly rewarding.”
About This Role
Designs industrial systems to mass-produce plant-based proteins, enzymes, or pharmaceutical compounds.
A Day in the Life
A Plant Bio-process Engineer designs, optimizes, and scales up industrial processes for producing plant-derived products. This involves developing bioreactor systems, optimizing fermentation conditions, troubleshooting production issues, and ensuring compliance with quality and safety standards.
- Design and optimize bioreactor systems for plant cell culture or microbial fermentation using plant feedstocks
- Develop and scale up downstream processing methods for product purification
- Monitor and control process parameters (temperature, pH, nutrient levels) to maximize yield
- Troubleshoot production issues and implement corrective actions
- Conduct economic feasibility studies and cost-benefit analyses for new processes
- Ensure compliance with Good Manufacturing Practices (GMP) and safety regulations
- Collaborate with R&D scientists to translate lab-scale processes to industrial scale
- Prepare technical reports, process documentation, and standard operating procedures (SOPs)
Work Environment
Works in a mix of office settings for design and analysis, and industrial plant environments or pilot facilities for process implementation and monitoring. May involve exposure to industrial machinery and controlled environments.
Typical hours: 45h/week · WLB score 6/10 · COMMON overtime
