Has the time come for you to roll up your sleeves at a company where sparks fly? At Sif – an international listed company – we make thick-walled steel construction piles (our XL monopiles weigh 1000 tons!) and other steel components for offshore wind turbines and jacket constructions. Wind farm developments are in full swing and present Sif with great opportunities. We grow with you and contribute to a sustainable future.


Sif has two locations: one in Roermond and one in Maasvlakte 2 (Rotterdam). We work together every day to create an impressive product that has to meet the highest quality standards. We work in an informal setting, but always with our shared goal in mind. We keep our promises, take responsibility, and help each other as a matter of course. Our organization is always evolving and gives you the freedom you need to grow and to work independently. Make it a success at Sif!
