Engineering & Maintenance Careers Engineer systems that make science real
Shaping science through smart engineering.
At Sanofi, you’ll work on complex, large-scale engineering challenges that directly impact patients around the world. This is where your expertise helps design, automate, maintain, and continuously improve the assets that turn breakthrough science into reliable, high-quality medicines and vaccines.
You don’t need a pharma background to thrive here. We welcome engineers from automotive, aerospace, robotics, energy, and advanced manufacturing – especially those comfortable with automation, digital systems, and fast-paced change. What matters most is curiosity, adaptability, and the drive to engineer better ways of working.
As part of our fully integrated Manufacturing & Supply network, you’ll see the full value chain – from facility design and commissioning to reliability, performance, and sustainability. With major investment in smart factories, AI-powered automation, and asset modernization, this is a moment to help shape how healthcare is made.
Here, you can grow your skills, move across technologies and geographies, and build a career that evolves with the science.
“I like that you see the impact of your work quickly – in performance, in reliability, and ultimately in patients getting what they need"
John Smith
Engineering Manager
