Maintaining and troubleshooting equipment. + Partnering with External Manufacturing group and other related functions at Regeneron’s Industrial Operations and Product Supply (IOPS) organization to provide technical assessment of CDMO’s GMP production capability (gap assessments) and provide technology transfer support to ensure first-time-right time performance. + Driving fermentation-purification platform development and new technology implementation to improve process performance, generation of predictive process models, and enhance process control and robustness + Cross-training on and providing support to formulation, analytical and upstream operations. + Support weekend or off-hour experimental and pilot scale work, as required **This Role Might Be For You If You:** + Enjoy working in the lab to advance exciting new drug modalities to patients. + Have a strong fundamental understanding of plasmid DNA and protein purification, process scale-up, and technology transfer principles. + Enjoy developing talent in junior team members. + You have strong initiative to complete challenging tasks and lead the evaluation of new process technologies. + You are capable of multi-tasking, thinking critically, working both independently, as part of a team, and as a team-leader. + Have excellent interpersonal, verbal, and written communication skills. This position requires a Bachelor’s degree in either Chemical Engineering, Biochemical Engineering, Biochemistry, or related field with 8-10 years, a Master’s Degree with 5-7 years, or a Ph.D with 0-2 years of meaningful experience. The extent of the candidate’s prior experience will determine the grade of the position. A strong fundamental understanding of the principles of purification process development, a history of developing downstream steps within bioprocesses, and process scale up is required. Experience preferred with the following systems: Depth filtration, Tangential flow filtration, Cell lysis, Centrifugation (e.g., continuous, disc stack), Ultrafiltration/Diafiltration, and Chromatography utilizing the Akta Avant 150/Pilot (e.g., ion exchange, hydrophobic interaction, and size exclusion). Proficiency with statistical analysis software (e.g., DOE, and Spotfire) is also required. Prior experience with purifying plasmid DNA is desired, and consideration will be given to similar experience with other biologics such as monoclonal antibodies, bispecific antibodies, adeno-associated virus, and other therapeutics proteins. **\#pmpd** **Intro To PMPD Video:** https://www.youtube.com/watch?v=pAboGKlI1zw&list=PL\_7lj13Lp4fH4OssUue8J5bby6muZsaR4&index=6 **Intro To Viral Production Core:** https://www.youtube.com/watch?v=KtR5\_mKkXlo Does this sound like you?
