The successful candidate will work closely with a multidisciplinary team to optimize and execute purification workflows using tangential flow filtration (TFF) and chromatography-based methods. This internship provides hands-on experience in biologics processing and analytical evaluation, contributing directly to process development for therapeutic nanoparticles.Onsite at our Marlborough, MA site,\nIn the Research Intern role, you will serve as a critical contributor to the development and integration of Sartorius’ emerging technologies for characterization and purification of different types of nanoparticles such as extracellular vesicles and viral vectors. These leading-edge platforms will be utilized in basic research as well as the pharmaceutical and biotechnology industries.\nWhat you will accomplish together with us\nExecute Purification Protocols: Perform purification of EVs and viral vectors using TFF systems (hollow fiber and/or flat sheet) and various chromatography modalities (e.g., ion exchange, size exclusion, affinity). Optimize Unit Operations: Assist in the design and optimization of downstream steps to improve product yield, purity, and scalability.\nSystem Operation and Maintenance: Operate and maintain TFF and chromatography systems (e.g., AKTA or equivalent), including set-up, cleaning, and troubleshooting.\nSample Handling and Quantification: Prepare and process samples following SOPs. Quantify particles using orthogonal methods such as NTA, qPCR, protein assays, and total RNA analysis.\nProcess Monitoring and Data Recording: Monitor and document key parameters (e.g., transmembrane pressure, flux, recovery) during TFF runs. Maintain detailed lab notebooks and process logs.\nAnalytical Support: Support integration of downstream data with analytical assays (e.g., flow cytometry, SEC-MALS, SDS-PAGE) for process characterization.\nCollaborative Work: Interact regularly with upstream, analytical, and formulation teams to align on process goals and transfer knowledge.\nSafety and Compliance: Follow laboratory safety protocols and ensure compliance with quality standards and experimental reproducibility.\n\nWhat will convince us\nEducation:\nPhD candidate in Bioengineering, or closely related discipline with formal education and experience with extracellular vesicles characterization and purification.\nExperience:\nHands-on experience with TFF systems (lab or pilot scale) for nanoparticle or biologics concentration and diafiltration.\nPractical knowledge of chromatography techniques such as SEC, IEX, or affinity purification.\nFamiliarity with nanoparticle systems such as EVs, viral vectors (e.g., AAV, lentivirus), or LNPs.\nComfortable working in a wet lab environment with complex biological samples.\nStrong documentation and organizational skills; experience with SOPs and batch records is a plus.\nExperience with analytical tools (e.g., NTA, BCA, qPCR, HPLC, or SEC-MALS) is highly desirable\n\nIdentification with our core values: Sustainability, Openness, Enjoyment\nCompensation is up to $30 hr.\nWhat We Offer\nAs a growing global life science company, with our stock listed on the German DAX and TecDAX , Sartorius offers a wide range of benefits:\nPersonal and Professional Development: Mentoring, leadership programs, internal seminar offerings\nMaking an Impact Right from the Start: Comprehensive onboarding, including a virtual online platform\nWelcoming Culture: Mutual support, team spirit and international collaboration; communities on numerous topics such as “Coaching”, “Agile Working” and a “Businesswomen’s Network”\nIntelligent Working Environment: Working in smart buildings with the latest technology and equipment.\nSartorius is an equal opportunity employer and will consider all qualified applicants for employment without regard to race, color, religion, sex, national origin, age, protected veteran status, disability or based on status in any other protected group of class.\nPlease view equal employment opportunity posters provided by OFCCP here.\nE-Verify Participation Info\nE-Verify Workers Rights\nSartorius is part of the solution in the fight against cancer, dementia, and many other diseases.
