Working at TILLEN

Our vacancies are exclusively aimed at candidates who wish to join us directly without involvement from staffing agencies and recruiters. We do not engage with freelancers either; acquisition based on these advertisements is not appreciated.

TILLEN was founded in 2007 by three enthusiastic engineers with a passion for heavy constructions and lifting equipment. The company designs and delivers customized solutions for the safe and efficient handling of heavy constructions, such as those for wind farms, contributing to the energy transition. The team comprises experts in mechanical engineering and structural engineering. By pooling these skills, tailored solutions are created, manufactured, and implemented for handling heavy and unwieldy loads. The expertise extends beyond heavy lifting, serving various markets. Designs range from specialized equipment to supporting structures and other handling devices with diverse applications. In addition to engineering, an increasing part of our activities involves manufacturing our designs, ultimately delivering complete solutions to customers. This process includes visiting the manufacturing workshop, devising and conducting tests, and participating in the final acceptance by the customer.

In addition to vacancies for Sales Engineers, Project Managers, and Structural Engineers, we are always looking for CAD Engineers, Design Engineers, and Project Managers. Please send your application to

Why work at TILLEN

Design Engineer

After completing my internship, I decided to stay on. The assignments are very diverse, so you never design the same thing for long. It's a smaller company, which means you have more direct contact with colleagues.
