Explore our expertise areas at Sanofi Geel

Manufacturing & Supply (M&S) is at the forefront of innovation, helping breakthrough medicines and vaccines reach patients faster than ever before. At Sanofi Geel, our teams across Engineering, Manufacturing, Quality, Science, and Supply Chain play a vital role in making that happen every day.

As this area of the business continues to evolve, so do the opportunities to grow, innovate, and shape the future of healthcare.

Technical Services

Behind every treatment, there's a site that delivers. That's where you come in.

In Technical Services, you're responsible for the maintenance and management of our entire site from process installations and utilities to buildings. You ensure everything runs safely, reliably, and efficiently in a highly regulated environment, so manufacturing never stops.

Manufacturing

In Manufacturing, you produce complex biological medicines designed to improve patients’ lives around the world. Using advanced bioprocessing technologies, you transform science into treatments people rely on every day.

On the production floor, you collaborate closely with teams from Quality and Technical Services in a continuous, fast-paced environment. You monitor processes, ensure compliance with cGMP standards, and adapt quickly to keep production running smoothly.

Quality Affairs (QA)

In Quality Affairs, you help ensure every product meets the highest standards of quality, safety, and compliance before reaching patients. Working independently from operational departments, you oversee and strengthen the site’s quality assurance system across the entire production process.

Manufacturing Sciences & Technology (MSAT)

The Manufacturing Sciences & Technology department (MSAT) connects science and manufacturing by transferring, optimizing, and qualifying processes and analytical methods, while supporting production and quality teams to ensure robust and reliable operations.

Supply Chain

Supply Chain connects the entire manufacturing process, from receiving raw materials to delivering finished medicines across the global network. You ensure materials are available where and when they are needed, enabling smooth and reliable operations across Manufacturing, Quality, and MSAT.

Behind this flow, teams manage storage, planning, logistics, and inventory, coordinating transport, materials, and data to keep the supply of medicines running seamlessly.
