Manufacturing & Supply
When you think "pharmaceutical", you may picture scientists in labs creating or researchers doing clinical studies. Those scientists and researchers are an important part of the effort, but there's much more to the story. Medication, after all, needs to get safely to doctors and patients. We have a dedicated team all over the country, making breakthrough inventions a reality through manufacturing, packaging, and distribution. As part of this team, you'll be inspired by a supportive culture, encouraging your ideas and empowering you with the best collaborators and resources possible.

I started at Merck in 1988 as a Biotechnician at our West Point, PA manufacturing plant. Getting this job turned into an amazing career. My current position in Regulatory Affairs has allowed me to partner with R&D, Manufacturing, and Marketing, leading to approvals of our vaccines in all of the regions. I've also been able to travel the world to meet and greet people of all cultures - it really doesn't get any better than this.
