Three questions for Markus:
Information Security and Quality Management Officer (QMB)—that sounds like a lot of responsibility. What does a typical workday look like for you?
„There’s really no such thing as a “typical” day, and that’s exactly what makes it so appealing. As a QMB, I ensure that our processes aren’t just on paper but are actually put into practice—always with the goal of exceeding our customers’ high standards. In information security, my focus is more on prevention: I analyze risks, raise my colleagues’ awareness of security issues, and ensure that our data—and that of our partners—remains confidential and secure.
Why do these two roles actually go so well together?
„Both areas aim to minimize risks and build trust. Quality management focuses on the excellence of our products and services; in information security, we protect the knowledge behind them. They are two sides of the same coin—at Holzer, we simply want to be reliable in every respect.”

Roles within the company
As a CAM programmer at the Holzer Group, Emran serves as the digital link between design and machinery. Emran creates virtual machining strategies on the computer for the production of complex components. Starting with a CAD model and a design drawing, he determines which tools, spindle speeds, and toolpaths a milling or turning machine will use to transform a blank into the finished component. He simulates the entire process in advance to avoid collisions and maximize efficiency.
Career at the Company: A Commitment to Information Security and Quality
Emran began his career with us in a traditional manufacturing role. As a CNC miller, he produced a wide variety of components on various 5-axis machines. After transitioning internally from milling to programming, he now works in the CAM department, bridging the gap between theory and practice. Thanks to his background as a trained machinist, Emran combines solid practical experience with modern software applications. He uses this valuable shop-floor knowledge strategically to optimize manufacturing processes right within the CAM system, refine machining strategies, and thus continuously improve quality and efficiency in production even before the first chip is cut.
Position: CAM Programmer (formerly a milling machine operator in production)
Category: Machining / Work Planning
Focus: Prototype Parts & Small-Batch Production for Motorsports and Aviation
Three questions for Emran:
Emran, you started out as a milling machine operator and have since moved up to the CAM department. What was that transition like for you?
“It was an exciting process. The great thing about Holzer is that internal promotion is truly a reality here. I was able to take the knowledge I gained from working on the machine—specifically, how the material behaves and how the tool cuts—and apply it directly to the computer. This transfer of knowledge is invaluable, because when I’m programming, I know exactly what’s happening out there on the shop floor.”
What makes working in machining at the Holzer Group so special?
“It’s clear: the complexity. We don’t manufacture mass-produced goods, but rather sophisticated parts for motorsports and the aerospace industry. Every prototype is a new challenge. Here, we work on projects that are at the cutting edge of technology. It’s a source of pride to see the finished part later on in a race car or an airplane.”
How do you find working with the team?
“Even though I spend a lot of time at the computer these days, I’m constantly in touch with my colleagues working at the machines. Their direct feedback is extremely important for optimizing the programs. We’re a great team where everyone learns from one another. It’s a continuous learning process—technology keeps evolving, and so do we.”
Roles within the company
For three decades, Jens Grün has been a mainstay of the Holzer Group. Where others shy away from complex assemblies, that’s when the fun really begins for him. As a certified welder, he is our specialist for anything that needs to be fast, precise, and technically demanding. As a welder in the motorsports sector, he works at the intersection of precision craftsmanship and engineering. Since components such as swing arms or control arms must withstand extreme loads while maintaining minimal weight, there is zero tolerance for error.
