We currently employ approximately 2,500 employees, across five sites in Ballydine, Co Tipperary, Brinny, Co Cork, Carlow and Dublin and, in addition, operate substantial Human Health and Animal Health businesses. Our new biotechnology facility MSD Biotech, Dublin, is currently under construction and will be completed in 2021 and we are also constructing a second manufacturing facility at our existing site in Carlow with the creation of 170 new jobs.

Our Irish sites manufacture approximately half of MSD’s top twenty products, saving and enhancing lives in over sixty countries around the world.

At MSD, we have and always will be…Inventing for Life. These three powerful words reflect our commitment to inventing new medicines and vaccines that save lives by preventing and fighting disease. MSD has dedicated researchers trained in many different scientific disciplines who work tirelessly to find cures for significant diseases that still afflict millions around the world and we will continue on this path. We offer employees hugely ambitious and exciting career paths, working at the cutting edge of science and technology, creating new treatments and products that save and enhance lives, playing a significant role in addressing the world’s most vital, unmet needs.

At MSD Ireland we firmly believe that the most important thing we make is a difference – to patients, to our employees, to our communities and to the Irish healthcare landscape generally. MSD Ireland is 100% committed to putting the patient at the heart of everything we do and we are also firmly focused on giving back to the communities that we operate in and bringing real value to the Irish healthcare landscape generally. Over the last five years we have consistently been ranked as one of the top five business contributors in Ireland and over that period our employees have volunteered over 1400 hours to a host of projects. In fact, our employees have helped and supported over 500 local projects and have contributed over €5.8 million to a range of worthy causes and projects.
