The ideal candidate will have practical experience executing downstream purification processes in a pilot, manufacturing, or process development environment and be comfortable operating chromatography and filtration equipment while working within controlled documentation and schedule-driven workflows.

Key Responsibilities

• Plan and execute pilot-scale downstream purification runs, including clarification, chromatography, TFF, viral filtration, depth filtration, and centrifugation.
  
• Prepare buffers and reagents and perform equipment setup, operation, cleaning, and teardown.
  
• Operate ÄKTA chromatography systems and UNICORN software for process execution and data collection.
  
• Pack and unpack chromatography columns and support chromatography process activities.
  
• Operate single-use equipment and filtration systems in a pilot-scale environment.
  
• Monitor process performance, analyze run data, identify process issues, and troubleshoot deviations in real time.
  
• Accurately document activities in SOPs, batch records, run sheets, and technical summaries.
  
• Communicate observations, process results, and troubleshooting findings to cross-functional teams.
  
• Support process scale-up, comparability studies, technology transfer, and laboratory readiness activities.
  
• Follow applicable safety, quality, and controlled-documentation procedures.
  
• Support occasional weekend or extended-hour coverage based on process schedules.
  

Required Qualifications

• AA/AS degree with 4+ years of relevant industry experience in downstream purification or bioprocessing; OR
  
• BS/BE degree in Chemical Engineering, Biochemical Engineering, Biochemistry, Biology, or a related field with 2+ years of relevant industry experience.

  • Chromatography
    
  • TFF
    
  • Viral filtration
    
  • Depth filtration
    
  • Centrifugation
    
  • Clarification
    
  • Buffer preparation
    
• Hands-on experience operating ÄKTA systems and UNICORN.
  
• Experience with chromatography column operation, including packing/unpacking, is highly relevant.
  

Preferred Qualifications

• End-to-end downstream purification experience rather than experience limited to a single unit operation.
  
• Biologics pilot plant or manufacturing experience.
  
• Experience supporting process development, scale-up, technology transfer, or comparability activities.
  
• Experience with single-use technologies and equipment.
