The largest biotech
facility in Ireland

What’s it like working at one of the world’s most innovative biotech companies?

In 2013, we established the European Business office, built the biggest bulk biologics facility in Ireland, hired over 1,400 people in Dublin and Limerick and received EU and US regulatory approvals to manufacture our medicines for commercial sale. Fueled by our robust pipeline and inspired by a relentless focus on science, we are united in our quest to deliver life-transforming medicines for patients with serious diseases.

Regeneron is a company where employees get the opportunities of a start-up mentality, with the perks of working for one of the most established and best employers in healthcare. Find out what it means to be on a mission to turn science into medicine.

Why Mid-West?

We chose Limerick as the location for our first-ever overseas manufacturing site to accommodate rapid growth and an expanding pipeline of medicines. Its central location allows our employees to choose to live nearby or enjoy an easy commute.

We asked our colleagues why they like living in the Mid-West. This is what they told us:

“A vibrant and thriving city full of culture and with a strong sporting heritage. The shopping, nightlife, and proximity to the Wild Atlantic corridor are all attractions that make Limerick a great place to live and work.”
