Work areas – what current trainees have to say

You can work in many different areas at Leadec and choose your specialization according to your interests and skills. To give you a small glimpse of the possibilities, we have asked three of our trainees to describe their activities.

Safety engineering

“In the field of safety engineering, we are responsible for maintenance work and troubleshooting. I find it exciting to come across a fault that no one has ever seen before and having to find out what caused it. It could be, for example, that a wire break has occurred because a tradesman from another company had to assemble something and caught our detector or wire in the process. When our system then reports a wire break, we look on site in the production facility to see which wire is affected and repair the damage. Working in safety engineering means having a lot of responsibility. You have to understand electrical engineering and be able to figure out solutions.”

Ivan,  3rd year of training

Control cabinet fabrication

“In the Leadec workshop, we build large control cabinets for our customers. This sometimes means working with 2-3 people on one control cabinet because the control cabinets are very complex. There are new requirements for each project. The project always begins with the order that is received by our head of department. We discuss the order within the team, plan the execution and prepare the parts. It’s then time to build the control cabinet, which means attaching fuses and control systems, doing the wiring and testing. This requires manual dexterity and care because every detail is crucial. At Leadec, all apprentices are assigned to a qualified coworker who they work with at all times and can ask anything. Without control cabinets, nothing would be supplied with electricity. With our work, we are therefore laying an important foundation for our customers.”

Gregor, 3rd year of training


“Even though I haven’t been with the company for long, I have already worked in a wide variety of locations. We work in offices, at small and large companies – one day we might be working on the roof and another day, in the cellar. There, we install lamps, lights and sockets, lay and connect cables or attach new brackets, for example. You learn most quickly if you can try things yourself. At Leadec, I can be on site from the very beginning and I am shown how everything at the construction site works. My colleagues are happy to help me when I don’t know exactly how something works or if I want to know something.”

Leon, 1st year of training

Good combination of theory and practice

“I can definitely apply everything I learn in the vocational school in my training. Measurements, for example, are an important part of electrical engineering but even if colleagues explain something to you in your first year of training, you may not understand it as well as you would like to. But if you then have it explained to you at school and at work, you will quickly get the hang of it. I sometimes have a real sense of accomplishment when I learn something new in school that I can then implement at work and see that it works.”
