Johnson & Johnson is a US-based multinational company that was founded in 1886 with the initial idea that wounds should be treated and dressed using sterile equipment. Over time it has grown to be one of the biggest healthcare companies in the world.

Johnson & Johnson operates three distinct divisions – medical devices (J&J MedTech), pharmaceuticals (Janssen), and consumer health (where it’s a leading name with brands such as Neutrogena, BandAid and Clean and Clear).

Products from these three divisions are marketed in 57 countries via almost 250 operating companies with global personnel of almost 156,000.

Johnson & Johnson in Ireland

Johnson & Johnson have had a presence in Ireland for over 80 years. Today, both the medical device and pharmaceutical divisions have manufacturing sites in the country and there are more than 5,000 people employed across sites in Cork, Galway and Limerick.

Since 2012, Johnson and Johnson have invested over $2 billion in their Irish operations.

The company is aiming for net-zero carbon emissions by 2030. As a step towards that, they announced that Irish operations were powered by 100% renewable energy in October 2021.

Johnson & Johnson in Cork

  • Employees in Cork: 2800
  • Activities: API Manufacturing, Biologics Manufacturing, Medical Device Manufacturing

There are three Johnson & Johnson manufacturing sites across Cork:

  • Janssen Little Island
  • Janssen Ringaskiddy
  • DePuy Ireland

Janssen Little Island

This Janssen Pharmaceutical manufacturing site has been operational since 1981. It is one of four within the company that make up the “small molecule cluster organisation”. The bulk active pharmaceutical ingredients that are manufactured here are used by other Janssen sites and third party companies around the world for use in tablets, creams and injectable dosage forms. Approximately 400 people are currently employed here.

Janssen Ringaskiddy

This Janssen Sciences site is responsible for biologics research, development and manufacturing. A €400m investment led to the opening of the site in 2005. It currently employs over 700 people and the 5 commercial products manufactured here are used in the treatment of cancer and immune related diseases.

The company describes this site as a “Global Centre of Excellence for Clinical Drug Substance and Drug Product Release and Stability Management”

In 2019, J&J invested €300m to expand the Ringaskiddy site and add 200 new jobs.

Then, in 2022, the company announced a €150m expansion that is expected to lead to another 180 jobs once completed.

“The strength of our people has been paramount to J&J’s success in Cork and Ireland.”

– Gary Hartnett, Site Lead at Janssen Sciences Ireland

DePuy Ireland, Ringaskiddy

DePuy Ireland is part of Johnson & Johnson MedTech. This medical device manufacturing facility produces orthopaedic and joint replacement products. It was opened in 1997 and is the now company’s largest manufacturing site for these products, which are then sold around the world. Approximately 1700 people are employed across a variety of roles here.

In 2015, DePuy Ireland’s Ringaskiddy site was awarded the Shingo Prize for operational excellence. It was then named as one of the top nine most advanced factories in the world by the World Economic Forum in 2018 for its use of Internet of Things (IoT) technology.

The company invested €36m in 2019 to establish additional R&D projects at the Depuy site. This investment led to the establishment of a 3D Printing Development & Launch Centre, as well as 30 additional jobs. As a result, the company was able to launch its “first commercial 3D printed knee product”.
