The new jobs will be in the areas of design engineering, commercial, and administration – recruitment for which has already commenced.

SEPAM, founded in 1976, is a global engineering and project management company with operations in Europe, the US, the Middle East, and Asia.

Company chairman Gus Kearney said: “SEPAM are delighted to be expanding our work force in Clonmel as we have a long and successful history working in Ireland and this new investment is a great vote of confidence in the workforce here. This is a win-win situation for Clonmel and will be a very positive benefit for all our customers.”

The company said the new jobs will help to further establish Ireland as a “centre for excellence” in engineering.

Commenting on the news, Taoiseach Leo Varadkar said: “I am very pleased to join the SEPAM team for their announcement of the creation of 100 new high-quality jobs - a welcome development for Clonmel and the Mid-West region.

“I love to see an Irish-owned business like SEPAM go from strength-to-strength, growing both at home and internationally. This is a great example of an Irish company achieving big things on the global stage.

“Today’s expansion is testament to SEPAM’s ambition and vision, and I wish them continued success.”
