Winter-Spring 2026 Co-Op - GMU CMC Purification Process Development

Job Title:  Winter-Spring 2026 Co-Op-Intern - GMU CMC Purification Process Development

About the Job

Are you ready to shape the future of medicine? The race is on to speed up drug discovery and development to find answers for patients and their families. Your skills could be critical in helping our teams accelerate Progress. 

The Genomic Medicine Unit within Sanofi is responsible for the design and optimization of viral vector manufacturing processes and platforms. We chase the miracles of science through exploration of novel technologies to enable better characterization of our next-generation production platforms and to enable high-dose gene therapy programs.

This 6-month position centers on viral vector purification processes but will interface with a broader team of vector and cell line engineering, upstream process development, analytics, and clinical manufacturing support.

A successful candidate in this role will be engaged in actively learning new techniques, independently performing experiments, analyzing and presenting results, and collaborating with different functions to understand the cross-functional nature of decision-making.

Experience in protein characterization, high-throughput, engineering and data analysis, analytical techniques, and/or viral vector purification is preferred. Project topic will be commensurate with level of previous experience. 

We are an innovative global healthcare company with one purpose: to chase the miracles of science to improve people’s lives. We’re also a company where you can flourish and grow your career, with countless opportunities to explore, make connections with people, and stretch the limits of what you thought was possible. Ready to get started?

Main Responsibilities:

• Design, execute, and analyze viral vector purification experiments.

• Perform analytical characterization of samples and analyze results.

• Work with cross-functional team for feedback and present findings.

• Contribute to technical reports and/or external publications if appropriate to project topic and level of experience.

About You

Must be permanently authorized to work in the U.S. and not require sponsorship of an employment visa (e.g., H-1B or green card) at the time of application or in the future. Students currently on CPT, OPT, or STEM OPT usually require future sponsorship for long term employment and do not meet the requirements for this program unless eligible for an alternative long-term status that does not require company sponsorship

Basic Qualifications:

• Currently pursuing a PhD, MS, or BS degree in biological sciences, biophysics, chemical engineering or related field at an accredit college or University with the expectation that you will complete your current degree by the Spring of 2028.

• Must be able to relocate to our Waltham office location and work 40hrs/week for the full duration of the Co-op/Internship.

• Understanding of cell engineering, molecular biology, virology and immunology concepts.

• Knowledge and understanding of technologies and operations such as Chromatography, tangential flow filtration, normal flow filtration, and/or viral clearance and inactivation.

Preferred Qualifications:

• Advanced analytical tools to characterize protein and viral vector.

• Ability to work in Biosafety Level 2, follow safe lab procedures, and maintain good laboratory practices (GLPs) including detail-oriented laboratory notebook documentation.

• Experience with viral vector purification and characterization.

• Experience with SEC-HPLC, DLS, ddPCR/qPCR, Western blot, ELISA, FACS, immunoassays, spectroscopic and bioassay techniques.

• Experience with AKTA automated chromatography instruments, high-throughput liquid handlers, and automated filtration instruments.

• Experience with protein sequences and tools such as NanoSight 3000, Caliper LabChip GXII, Multi-Angle DLS (MADLS), ForteBio Octet, or similar instruments.

• Basic understanding of the principles of Quality by Design and ability to apply DOE to downstream development.

• Excellent communication skills and ability to build cross-functional relationships.

• Work under minimal supervision and function within a collaborative, team-oriented environment.
  

Why Choose Us:

• Bring the miracles of science to life alongside a supportive, future-focused team. 

• Discover endless opportunities to grow your talent and drive your career, whether it’s through a promotion or lateral move, at home or internationally. 

• Enjoy a thoughtful, well-crafted rewards package that recognizes your contribution and amplifies your impact. 

• Exposure to cutting-edge technologies and research methodologies. 

• Networking opportunities within Sanofi and the broader biotech community.
