  • Maintain thorough, accurate and detailed documentation of all work produced in batch records, databases or other acceptable formats including problems and deviations
  • Define reagent specifications, processing parameters and operational boundaries
  • Use of statistical tools to establish production processes/ formulations
  • Set up part numbers and bills of material 
  • Write work instructions, SOP’s and training documents for the manufacture of reagents and for transition to manufacturing operators
  • Transition process and documents for  manufacture of reagents and for transition to manufacturing operators
  • Train manufacturing operators on proper reagent handling and usage
  • Design a reagent build schedule and scale to a plan or record based on forecast
  • Assure reagent manufacturing team functions to ISO standards 
  • Excellent verbal and written skills

Minimum Qualifications:

About Twist Bioscience

At Twist Bioscience, our expertise is accelerating science and innovation by leveraging the power of scale. We have developed a proprietary semiconductor-based synthetic DNA manufacturing process featuring a 10,000-well high throughput silicon platform capable of producing synthetic biology tools, including genes, oligonucleotide pools and variant libraries. By synthesizing DNA on silicon instead of on traditional 96-well plastic plates, our platform overcomes the current inefficiencies of synthetic DNA production, and enables cost-effective, rapid, high-quality and high throughput synthetic gene production, which in turn, expedites the design, build, test cycle to enable personalized medicines, pharmaceuticals, sustainable chemical production, improved agriculture production, diagnostics, biodetection and data storage.
