Marja Vilkman, Oura
"If I start to feel too comfortable and it feels like I know exactly what I'm doing, it's usually a sign that I'm ready for a new challenge."
What have you studied and what influenced this choice back in the day?
I originally planned to study biochemistry. However, once I began studying chemistry at the Helsinki University of Technology (now Aalto University), I realized how much I enjoyed the lectures on polymer technology, so I chose it as my major. Later, I learned about conducting polymers and fell in love with the subject. I chose physical chemistry as my minor and eventually pursued doctoral studies in the physics department, where I completed my PhD thesis on conducting polymers.
It is quite funny because I took only one physics class in high school—I thought physics was not for me. Yet I ended up earning a PhD in a physics department.
How did you end up in your current position?
I worked at VTT Technical Research Centre of Finland for more than 20 years, developing several flexible electronics applications. About ten years ago, I decided to focus on batteries, and that turned out to be a great choice. In 2025, an opportunity arose to join Oura as a Battery Technology Specialist. It was a chance to bring my experience in batteries and flexible electronics into industry—and once again, it turned out to be a great choice!
I have never had a detailed, long-term plan for my career. Instead, I have usually chosen something that sounded interesting and changed direction when it felt right. Looking back, it seems that all the choices I have made have guided me towards a position that fits me perfectly. Perhaps that is what happens when you follow your interests and have the patience and courage to learn new things—even when you initially feel that you have nothing useful to offer.
What is the best thing about your job?
I like the fast pace and the fact that I can see the impact of my work quickly. I have clear goals, I can focus on the things that matter, and I love solving complex problems. Most importantly, I am happy that I can use my expertise at Oura to have a positive impact on people’s well-being.
What have been the highlights and key lessons of your career?
I have learned that if I become too comfortable and feel that I know exactly what I am doing, it is usually a sign that I am ready for a new challenge. By keeping an open mind and staying curious, I have found new and interesting things to do. First at VTT, by taking on new responsibilities and exploring new research topics, and more recently by moving from the academic world into industry.
What are your plans and goals in the future?
The future of my role is exciting: there are always new innovations and ways of thinking to explore. I cannot share anything too specific, but I am excited about what the future holds.
What kind of person is suitable for your profession?
The beauty of this profession is that we work as a team, and teams need different kinds of people. For example, I am quite introverted and pay close attention to details. At the same time, I enjoy presenting my work to others because explaining it is also a good way to develop a deeper understanding of what is important.
If I had to name one important skill, it would be listening. Of course, that applies to many professions, but it is often overlooked.
Your greetings for young people in high school deliberating their future career?
First of all, do what feels right for you. If something interests you, go for it. You can always change direction later if your first choice no longer feels right.
It is never too late to learn new skills, but it is important to keep learning throughout your life. Learning comes naturally when you explore things that matter to you and align with your values.
