• Use scientific knowledge of polymer science to strategically identify new technologies and create new capabilities for different businesses, such as academia, pharma, and industry by proving novel polymeric products or a total solution in gene delivery, drug delivery, bioprinting, and packaging applications;
• Take lead independently coming up with a full detailed technical plan with new ideas for novel polymers in drug delivery, gene delivery, tissue engineering, 3D bio-printing and biodegradable packaging. The employee in this role will diversify our product portfolio by focusing on newer areas as compared to our typical portfolios;
• Spend time identifying and synthesizing potential monomers and small molecules (example: chain transfer agent, new catalysts for fast polymerization) for our customers and for inhouse use;
• Run polymerization reaction on a regular basis to screen the scope of new polymer development by following different well-known techniques: ring opening, polycondensation, RAFT, ROMP, NMP etc.;
• Scale up the existing synthesis procedure from gram to kilogram scale while following safety procedures by implementing hazard evaluation and engineering control using skills and knowledge in polymer science;
• Perform process characterization techniques necessary (NMR, ATR-IR, CHN, DSC, XRD) during both small and scale up synthesis;
• Contribute to the development of minimum product specifications by designing a plan for experiments using internal (analytical and QC department) resources only;
• Focus on developing additional product specifications for new and existing products, with a potential need to use external resources (sending samples to external labs in academia or industries);
• Contribute to transferring technology for manufacturing by breaking down complex chemistry in Master Production Record (MPR) document for the in-house produced products;
• Work to clear high value back-ordered products by running the synthesis, purification, and characterization when needed. Also assisting in setup required for scale-up and pro-actively guiding production scientists to solve any issues during the bulk batch synthesis;
• Test polymer samples by using various instruments (GPC, MALLS, microplate reader, GC etc.) to expedite new product development and maintain the necessary instruments for the whole Material Science R&D team. Scientist needs to spend a good amount time measuring the specific refractive index increment (dn/dc) by using Opti Lab instrument (dRI detector) for the new and existing natural polymer portfolio;
• Be ready to develop any new QC methods and techniques at the R&D level and transfer it to QC to expedite new product clearance and tackle the bottleneck in the clearing process;
• Support internal collaborations by generating application data for new and existing products using the help of the drug delivery team;
• Share technical insight on new products so that other team members can use the product to make a kit for drug delivery, apply it as a potential bio-ink, etc. Synthesize novel polymers for other team members so that they can use these polymers for their application needs. Contribute to solving technical challenges and providing solutions for other team members in R&D using skills and knowledge in polymers;
• Act as a quality liaison for R&D by managing ISO audits, assigning…
