Since 1961, we have delivered track, civil engineering and infrastructure projects across Germany and Switzerland – as a certified partner to Deutsche Bahn, to energy providers and to municipalities. Over 200 employees, our own fleet of machinery, our own material supply. One point of contact for every trade.
At Klefenz, you'll work for a family-run business that has been growing on the Upper Rhine since 1961 – with over 200 colleagues, a modern fleet of machinery and projects you'll still be proud to point to 30 years from now. From track construction for Deutsche Bahn to fibre-optic network expansion for your local community.
We offer fair pay, secure jobs and genuine career paths – from apprentice to foreman, from machine operator to site manager. What counts here is craftsmanship, reliability and the will to take on responsibility.

Through Fretus AG, Klefenz extends its network with a specialised partner based in Switzerland. The partnership combines experience, technical expertise and clearly defined core competencies – delivering additional know-how, strong specialist input and even greater reliability in execution.
Hier teilen wir, was bei uns passiert: Projekte, an denen wir gerade bauen. Menschen, die seit Jahren oder seit Wochen Teil unseres Teams sind. Investitionen und Entwicklungen im Unternehmen. Keine geschönten Erfolgsmeldungen, sondern konkrete Berichte aus dem Alltag.
Whether you are planning a demanding construction project or looking for a new career path – Klefenz stands for experience, reliable collaboration and a clear commitment to quality. If you want to realise a project with us or become part of our team, we look forward to starting the conversation and taking the next step together.
