• Support the design and implementation of plant improvement projects, including capacity, reliability, and safety upgrades.
• Provide hands-on technical support to operators and technicians during daily operations, startups, and shutdowns.
• Analyze process data to identify bottlenecks, inefficiencies, or deviations, and implement corrective actions.
• Develop and maintain process documentation, SOPs, and operating standards.
• Collaborate cross-functionally with the R&D, Maintenance, and Controls teams to translate insights into improved process performance.
• Support implementation of Six Sigma and continuous improvement initiatives.
  

About You

• B.S. in Chemical Engineering, Biochemical Engineering, or related field.
• 5+ years of hands-on experience in production, process, or operations engineering within a chemical, biochemical, or bioindustrial plant environment.
• Direct experience with either fermentation or distillation systems is required.
