Joining BIOTRONIK: Onboarding at the Application Lab

How did you first learn about BIOTRONIK?

I was already very interested in the field of medical technology while I was at university. I’m particularly fascinated by the high technical standards required for the products and their manufacturing—that’s what makes the work so challenging and varied.

During my research, I quickly came across BIOTRONIK, partly because the company is known as one of the major medical technology manufacturers in Berlin. In addition, some of my friends have already worked here and recommended BIOTRONIK to me as an employer. These positive impressions encouraged me to apply.

What convinced you to join the company?

BIOTRONIK stands for progress, innovation, and the highest quality.  The high demands of development and production constantly present new technical challenges, and that's exactly what I find exciting.

I was particularly drawn to the opportunity to work in the field of additive manufacturing. This technology is currently evolving at a rapid pace. I was excited from the very beginning by the idea of combining innovative medical technology and modern manufacturing processes in a single role.

Was there a particular moment during the application process that stands out in your memory?

Yes, my second job interview really stands out in my memory. In total, I had two interviews—one online and one in person. During my very first interview, I had the opportunity to meet my current supervisor and a colleague from the HR department. I really appreciated that because it gave me the opportunity to demonstrate my professional skills right away. They also provided me with a lot of insight into my future role and were very transparent about the initial challenges of the position.

During the second in-person interview, however, we discussed my responsibilities in even greater detail. I met the team at the office and was shown around my future workplace, including the machines and parts of the Equipment Manufacturing department. I especially enjoyed the tour of the various areas of the large BIOTRONIK campus, as well as the pacemaker museum in the lobby. I was very impressed by the team's openness and enthusiasm. At that moment, I felt that BIOTRONIK was exactly the right place for me.

How did your first day go?

My first day was also a site-wide Welcome Day for all new employees. We received a warm welcome and had the chance to get to know one another. I especially appreciated that we talked openly about potential initial hurdles—that made a lot of things feel more tangible.

I also remember the icebreaker game “Two Truths and a Lie.” There was also a lot of practical information that made it easier to get started, such as how to report sick, where the cafeteria is, and how to access the meal plans. 

My team took great care of me right from the start: we had lunch together, I got my first glimpse into production, and I went through a structured onboarding process with a buddy and a training plan. That gave me a sense of direction and security.

What helped you the most during your orientation?

Definitely my coworkers. Everyone was very open, helpful, and took plenty of time to explain the technologies, equipment, and processes to me.

I familiarized myself thoroughly with the machines, programs, and tools used and learned what requirements the manufactured components must meet. It was particularly helpful that my colleagues openly addressed not only the strengths but also the challenges of the processes. Many of my questions were about the programs and tools used here. There are different systems for different needs—so it’s easy to get confused at first. In addition, some applications are not particularly intuitive, so training was sometimes necessary. And, of course, I had a lot of questions about the background and procedures: Why are certain processes or structures the way they are today? Often, the answer came with a smile: "That's just how it has historically developed." This transparency helped me quickly grasp the big picture.

Was there anything that pleasantly surprised you?

Yes, the wide range of activities beyond the daily work routine. In addition to sports groups like volleyball and rowing, there are many networks and opportunities for interaction.

I’ve already attended the Women’s Lunch for FLINTA networking, signed up for the internal BIO Networking Hub, and am currently planning to start a BIOTRONIK bouldering group with colleagues. From a professional standpoint, I also find initiatives like the Technology Board very exciting, as they showcase new technologies and provide insights into current and future developments.

Is there anything that particularly excites you, either at work or in your personal life?

At work, what excites me most is delving deeply into new technologies and developing solutions that are sustainable in the long term. I enjoy building and developing things.

In my free time, I enjoy playing sports and trying out new activities. Interacting with colleagues outside of work is a nice way for me to unwind and helps strengthen our sense of community.

What advice would you give to applicants who want to start at BIOTRONIK?

I recommend taking the time to thoroughly research BIOTRONIK, its technologies, and the underlying standards and values before applying. This helps you understand the responsibilities that come with working in the medical technology field—and makes both the application process and the transition into the role easier.
