What defines us

We live by The Regeneron Way  values that define who we are, what we do and how we do our work.

Lead with science

Science drives our business and passion drives our science. Whether you're doing science, supporting science or delivering science. It's what we do.

Take on big ideas

We take the long view and tackle the big ideas, the unsolvable problems, and the bottlenecks that get in the way. We pursue ideas with passion and courage, to make a real difference.

Make it happen

It may not always be easy, but we figure it out and get it done. We have a little appetite for unnecessary bureaucracy that can get in the way of innovation or quality.

Be great together

While others talk about teamwork, we actually do it. When you work with smart, fun people, you bring out the best in each other and can do the extraordinary.

Do what's right

We do well by doing good. We act with integrity and pride ourselves on doing the right thing — by each other, our communities, our patients and the world around us.

What inspires us

We are inspired by the personal stories of patients and the impact diseases have on their lives and their families. We are motivated by our colleagues who are heroes, volunteers, scientists and more. 

Our employees are at the center of our discoveries and solutions we deliver to patients. We invest in their futures by building a high-engagement culture that recognizes their unique contributions and backgrounds and supports their development. 

Changing the world from the inside out

Ensuring the health and well-being of our people and their families is just as important to us as the patients our life-transforming medicines serve. That's because we know caring for people around the globe should start with supporting our employees and their families.

From wellness-at-work benefits, perks and sports clubs to community volunteering initiatives, onsite celebrations and employee interest groups, our employees not only share science, they share a passion for doing well by doing good. Learn more.

Word from the top

When Regeneron hired our first Irish employee in 2014, we set out to build a very different kind of company, one driven by science and an unwavering commitment to our patients, our people and the broader Mid-West region. At the time, Limerick was just emerging from some bleak years, and we were honoured to bring high-end specialist jobs to the region. Today, Regeneron is a leading biotechnology employer in Ireland and a Great Place to Work®.

With the support of the IDA, local universities and community leaders, we’ve created more than 1,400 direct jobs in Limerick and even more indirect jobs across multiple industries. We attribute our success to our exceptional people and the unique culture we work hard to sustain - one rooted in a shared vision, innovation, teamwork and a deep commitment to taking care of each other. We are committed to helping the Mid-West grow and thrive. We will continue to leverage our mission, people and culture to strengthen an increasingly vibrant Limerick.

Application tips

The candidate fit – finding people who fit our culture

Regeneron is a select team of dedicated people from all walks of life who work together to achieve our goals. Developing new medicines is a long-term effort, and we approach talent and recruitment with that same long-term view, starting from the very first candidate interaction. Our success over three decades is directly linked to our unique science-driven culture. Our hiring process emphasizes the company, rather than on a specific job that needs filling. We look for candidates that embody The Regeneron Way – the values that we stand for and the basis for who we are and how we operate – during interviews. That way both parties have an opportunity to get to know each other and decide if there’s a good fit. We believe this approach helps candidates self-select for cultural fit — and our frontend emphasis on culture helps ensure better long-term success.

Our great workplace

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

Since 2013, we have built the largest bulk biologics facility in Ireland, hired over 1,400+ people and received EU and U.S. regulatory approvals to manufacture our medicines for commercial sale. Fuelled by our robust pipeline and inspired by a relentless focus on science, we are united in our quest to deliver life-transforming medicines for serious diseases.

This 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. Learn what it means to be on a mission to turn science into medicine.
