Discover Impactful Work You will join a team performing all tasks related to protein purification. You will work in a controlled manufacturing laboratory environment using protein purification equipment and analytical techniques. As a Scientist III, you will also serve as a technical resource for purification processes, troubleshooting, and continuous improvement activities.

A Day in the Life • Purify protein products in a laboratory setting in accordance with standard operating procedures and controlled manufacturing documentation. Utilize laboratory techniques, calculations, materials measurement, equipment operation, and accurate record-keeping. • Perform column purification/chromatography, tangential flow filtration (TFF), buffer preparation, SDS-PAGE analysis, Western blotting, and other protein characterization techniques. • Operate Cytiva ÄKTA FPLC systems using UNICORN software and Bio-Rad NGC chromatography systems. • Apply specialized technical knowledge of protein purification and chromatography to make detailed observations, analyze process data, evaluate chromatograms, and ensure processes are operating within established parameters. • Independently identify and troubleshoot process, equipment, and product-related issues and recommend appropriate technical solutions. • Maintain accurate Batch Data Records, laboratory notebooks, work orders, equipment records, and other required documentation. • Maintain equipment, materials, product inventories, and related records as assigned. • Author and revise technical documents, including standard operating procedures and manufacturing batch records, within the requirements of the Quality Management System. • Lead or substantially contribute to process improvement activities to improve product quality, yield, process robustness, and productivity. • Support validation, qualification, investigations, and implementation of new or revised manufacturing processes as required. • Serve as a technical resource and provide guidance and training to less-experienced team members on protein purification processes and equipment. • Comply with all company safety procedures, Quality Management System requirements, and EH&S programs and maintain knowledge of Safety Data Sheets (SDSs) for relevant materials. • May perform other related duties as required and/or assigned.

Keys to Success: Education • Bachelor’s degree in Biology, Chemistry, Biochemistry, or another related discipline required. A Master’s degree in a relevant field is preferred.

Experience • 5+ years of work experience in protein purification within a manufacturing environment or R&D laboratory. • Demonstrated hands-on experience with Cytiva ÄKTA FPLC systems and UNICORN software and/or Bio-Rad NGC chromatography systems. • Extensive experience with multiple chromatography modes, including affinity, ion-exchange, size-exclusion, and hydrophobic interaction chromatography, with a strong understanding of protein/resin interactions. • Demonstrated ability to independently troubleshoot protein purification processes and resolve technical problems using scientific principles and data analysis. • Experience with tangential flow filtration (TFF) and other downstream protein processing techniques. • Experience in executing validation or qualification protocols is preferred. • Experience working within a Quality Management System; experience with ISO 9001 and/or GMP environments is strongly preferred.

Knowledge, Skills, and Abilities • Strong theoretical and practical understanding of protein chemistry, chromatography methods, and protein purification techniques. • Demonstrated scientific troubleshooting and problem-solving skills. • Ability to independently execute scientific procedures, analyze results, and identify opportunities for process improvement. • Results-oriented and data-driven with excellent attention to detail and documentation practices. • Proactive approach that anticipates needs and problems while developing effective solutions. • Strong collaborative and communication skills with the ability to provide technical guidance and influence others without direct authority. • Ability to manage multiple priorities effectively in a manufacturing environment. • Working knowledge of manufacturing-related computer software preferred. • Intermediate Excel skills.

Working Conditions • Works in a clean, controlled manufacturing laboratory environment with specialized equipment. • Regularly required to lift up to 20 pounds. May occasionally be required to lift 45 pounds or more with assistance and/or appropriate equipment. • May be required to stand for extended periods while performing duties. • Must be flexible to work varying schedules and hours as needed. • Must be able to work safely with chemicals and hazardous materials. • Must be able to work in a +4°C cold room.
