Career Stories at PTW

My name is Alena Treyer, I’m 24 years old, and I’m originally from Pfaffenweiler just outside Freiburg. I’ve been part of the PTW family since September 2019. I currently work in accounting and also assist with controlling.

My job is very varied and multifaceted. My primary focus is on accounts payable—I review, post, and pay the invoices we receive from our suppliers. At the end of each month, I also prepare various tasks for the monthly closing.

Another important area is employee time tracking. In addition to recording and correcting working hours, breaks, and absences, we provide time data for payroll and generate statistics for management, HR, and controlling. Currently, I’m also supporting the Controlling department, which makes my role even more diverse: I create reports and statistics and share responsibility for two of our subsidiaries.

I came to PTW through my brother, Jannic Treyer. He completed his apprenticeship as an industrial mechanic here—and as is often the case with older brothers, they tend to serve as role models.

So I, too, decided to pursue an apprenticeship as an industrial management assistant at PTW. After graduating in 2022, I initially worked in purchasing. I moved to accounting in 2023, and that’s where I still work today.

Thanks to various supervisors, it became clear to me early on that I could imagine a future as a manager. My goal is to later support and challenge employees in a similar manner to my own experience.

To ensure that I am well-prepared professionally, I decided to continue my education in 2023 to become a certified accountant. However, it was a major challenge to balance my training and my daily work. Thanks to the support of my colleagues, managers and PTW as a company, I successfully passed the exam in February 2026. I am very grateful for that. Now it’s time for me to put what I’ve learned into practice – because you never stop learning.

I particularly appreciate the flat hierarchies and the fact that we work as equals. Collaborating with other departments is enjoyable because mutual understanding and support are our top priorities.

My name is Zahra Azadi, and I work in production. As an electronics technician, I work with the testing team to ensure that all devices are tested before they are shipped to customers.

I work as a tester and am therefore responsible for testing all devices to ensure they function properly and are safe to use. If problems do arise, I analyze the causes and remedy the issues through targeted repairs.

When I came to Germany, I learned about the dual vocational training system and was immediately intrigued. I found the combination of theory and practice very exciting. I came across the company PTW through the Employment Agency’s website. I wanted to join a medical company as an electronics technician because that kind of work requires a high degree of precision and is directly related to people’s health. In addition, you work with a variety of different devices, ranging from small to large. At the same time, I find it fascinating that modern medical devices combine many different electronic components. During my apprenticeship, I got to know several departments in production. After completing my apprenticeship, I initially worked in assembly where I populated circuit boards before later moving to the test lab where I work today.

What I particularly like about working here is the supportive atmosphere. Everyone helps each other, and we really work as a team. On top of that, the tasks are varied, so it never gets boring.

My name is Jannic Treyer. I completed my apprenticeship as an industrial mechanic at PTW and I have been with the company for a total of 10 years now. I currently work at the company’s production site in Umkirch, where I operate large CNC machines.

We operate on a two-shift schedule, alternating weekly between the early and late shifts. I oversee a turning and milling centre where I manufacture components for PTW’s products. My responsibilities include setting up and running the CNC machines, as well a carefully measuring and inspecting the finished parts.

I first learned about PTW through a job advertisement in the newspaper. I then began a 3.5 year apprenticeship and was subsequently hired by the company. I have completed several internal training programs over time and I also work as a trainer for industrial mechanics today.

Currently, I’m operating the largest machine in our workshop, something that makes me especially happy. As well as being technically challenging, it requires a great deal of knowledge and experience.

I really enjoy my work at PTW because it’s so varied. What’s especially motivating is seeing what can be created from raw materials at the end of the day.
