Get to know Stefan Mårtensson!

Our most camera‑shy colleague has finally agreed to step into the spotlight in a co‑worker interview, where we get a glimpse into his everyday life at Gammadata and what keeps him motivated after all these years.

Hi Stefan! Tell us about your role at Gammadata?
I work within the Radioactivity business area, with products and customers in several different industries – a real mix! A large part of my work is about staying in close contact with both customers and suppliers.

What is the best thing about your job?
The best part is that my knowledge is constantly being challenged, because the questions I get can be incredibly varied. On top of that, my tasks are very diverse, which is fun. One day it’s nuclear technology questions, another it’s about accrediting a dosimetry service, and the next it’s administering a website.

How would you describe a typical workday for you?
A typical workday involves a lot of emails – that’s just part of the job. I always try to start the day with a plan for what I want to get done, but quite often things happen that send the day in a different direction. So even if the calendar looks structured in the morning, there’s usually quite a bit of improvisation as the day goes on.

How has your role changed since you started, and what have you learned?
Even if my formal role is more or less the same as when I started at Gammadata, a lot happens in 17 years – both with the company and with me as a person. Over the years, I’ve built up experience and become much more confident in my professional role. Today, there are some very practical tools available – read: AI – and the days of leafing through old textbooks from my student days are over.

Which task or project are you most proud of having completed?
One project that really stuck with me was when we developed a personnel screening system and accompanying software in a fairly short time in connection with an assignment. It was time-critical, technically challenging and required very close internal collaboration. It’s the kind of project you look back on and feel: “We really did a good job there.”

What is the most challenging part of your role, and how do you handle it?
The most challenging part is the strategic questions: what should we do in one or five years to ensure our business is still in demand, and how do we make the best use of our internal resources? There are no obvious answers, and the world around us is changing quickly. To handle this, I try to stay up to date scientifically, listen to our customers, and dare to question old truths. It’s about balancing short-term needs with long-term goals.

What makes you enjoy working at our company in particular?
I enjoy it because the work tasks are fun and because there is a relaxed company culture where you can be yourself. The atmosphere is open, but still professional.

Is there anything about your job that people often don’t understand, but that you wish they did?
Not really to any great extent. Most people have a pretty good understanding of both what I can do and where my limitations are. If anything, it might be that behind a “simple” answer to a customer there’s often quite a lot of analysis, trade-offs and experience. But overall, I think people understand my role quite well.

How did you end up working in this industry?
It was actually quite a coincidence! The plan was clear: after my basic studies in physics, I was going to choose meteorology as my specialization. But the presenter for the Radiation Physics track said one sentence that felt very important at the time and stuck with me: “Everyone who studies Radiation Physics gets a job straight away.” That comment made me rethink. I chose radiation physics, which eventually led me onto the path I’m on today. So a fairly spontaneous decision back then has shaped my entire career.

What is the best thing about our company culture?
The best thing is freedom with responsibility. You get a lot of room to organize your own work and take responsibility for your tasks, while knowing that colleagues and the organization are there for support. It’s a culture built on engagement, where the important thing is that things get done and that customers are satisfied – not that every minute is controlled in detail.

What is your favorite memory from your time at the company?
One memory that stands out is the amazing welcome I received when I started, especially from Stefan Isaksson, who unfortunately is no longer with us. It made me feel welcome from day one and set the tone for how I still view the company today.

How would you describe the atmosphere in your team?
The atmosphere in the team is very friendly, with a strong sense of loyalty to one another. If you need help, you get help, period. There’s low prestige, lots of humor, and a strong willingness to solve things together.

Why would you recommend someone to apply for a job here?
I would recommend Gammadata because it’s a fun workplace where you get to work with tasks and products you won’t find in many other places. You also get to work in an environment where there is knowledge, commitment and humor, which makes a big difference in everyday life.

How do you celebrate small wins at work?
If I’m honest: far too poorly. We’re often quick to move on to the next task or project as soon as something is finished. Sometimes there’s a fika, a high five, or a quick “good job” in passing, but we could probably get better at pausing and actually celebrating the small wins a bit more.

What hobbies or interests do you have outside of work?
I enjoy an active lifestyle with lots of outdoor activities. Skiing and fishing are my two main interests, and I try to get out as often as possible, regardless of the season. Lately, golf has also snuck into my life, which is really fun!

How do you unwind after a hectic workday?
After an intense day, it’s pretty simple: ice cream and YouTube.

What is a fun fact about you that not many people know?
A fun fact is that I really don’t like being in photos. I much prefer to be behind the camera rather than in front of it. If there’s an opportunity to slip away when someone wants to take a group photo, I often take it.
